Different types of Faults

Interactions of an object with another object can be explained and predicted using the concept of forces, which can cause a change in motion of one or both of the interacting objects. An individual force acts on one particular object and is described by its strength and direction. The strengths of forces can be measured and their values compared. What happens when a force is applied to an object depends not only on that force but also on all the other forces acting on that object. A static object typically has multiple forces acting on it, but they sum to zero. If the total vector sum force on an object is not zero, however, its motion will change. Sometimes forces on an object can also change its shape or orientation. But at speeds close to the speed of light, the second law is not applicable without modification.

In the nineteenth and twentieth centuries physicalism emerged as a major unifying feature of the philosophy of science as physics provides fundamental explanations for every observed natural phenomenon. New ideas in physics often explain the fundamental mechanisms of other sciences, while opening to new research areas in mathematics and philosophy. Chemistry and Outline of chemistry Chemistry the etymology of the word has been much disputed [10] is the science of matter and the changes it undergoes.

The science of matter is also addressed by physics , but while physics takes a more general and fundamental approach, chemistry is more specialized, being concerned by the composition, behavior or reaction , structure, and properties of matter , as well as the changes it undergoes during chemical reactions.

Many more specialized disciplines have emerged in recent years, e. Earth science and Outline of earth science Earth science also known as geoscience, the geosciences or the Earth sciences is an all-embracing term for the sciences related to the planet Earth. There are both reductionist and holistic approaches to Earth sciences. The formal discipline of Earth sciences may include the study of the atmosphere, hydrosphere, oceans and biosphere, as well as the solid earth.

Typically Earth scientists will use tools from physics , chemistry , biology , geography , chronology and mathematics to build a quantitative understanding of how the Earth system works, and how it evolved to its current state. Ecology and Outline of ecology Ecology from Greek: Topics of interest to ecologists include the composition, distribution, amount biomass , number, and changing states of organisms within and among ecosystems.

What a bottle was used for is referred to on this website as a “bottle type” or “type of bottle”, i. The process of ascertaining what a bottle was used for is termed typology or simply “typing” and is the subject of this webpage and the many connected sub-pages. Since it was the contents of a bottle that guided the consumer in making a selection, not the bottle itself, contents are the most important consideration in establishing categories for bottle classification Herskovitz Glass containers are engineered along very specific design principles.

Container size, orifice diameter, neck length, and other attributes as well as the rations between such morphological characteristics are determined largely by such basic principles as frequency of access, amount of contents removed with each access, and the type of content bulk solid, liquid, semi-liquid, etc. Most bottle shapes were closely associated and identified with a certain product or products as “form follows function” to a large degree in bottle shapes and styles.

The three types of rocks. It’s the first thing you learn in a geology class — very briefly the three types of rocks are. Igneous — they form from the cooling of magma deep inside the earth.

A phenotypic characteristic, acquired during growth and development, that is not genetically based and therefore cannot be passed on to the next generation for example, the large muscles of a weightlifter. Any heritable characteristic of an organism that improves its ability to survive and reproduce in its environment. Also used to describe the process of genetic change within a population, as influenced by natural selection.

A graph of the average fitness of a population in relation to the frequencies of genotypes in it. Peaks on the landscape correspond to genotypic frequencies at which the average fitness is high, valleys to genotypic frequencies at which the average fitness is low. Also called a fitness surface. A behavior has adaptive logic if it tends to increase the number of offspring that an individual contributes to the next and following generations. If such a behavior is even partly genetically determined, it will tend to become widespread in the population.

Then, even if circumstances change such that it no longer provides any survival or reproductive advantage, the behavior will still tend to be exhibited — unless it becomes positively disadvantageous in the new environment. The diversification, over evolutionary time, of a species or group of species into several different species or subspecies that are typically adapted to different ecological niches for example, Darwin’s finches. The term can also be applied to larger groups of organisms, as in “the adaptive radiation of mammals.

A mode of coping with competition or environmental conditions on an evolutionary time scale.

How To Date By Personality: The 16 Personality Types And Dating For The Perfect Match

See Article History Dating, in geology , determining a chronology or calendar of events in the history of Earth , using to a large degree the evidence of organic evolution in the sedimentary rocks accumulated through geologic time in marine and continental environments. To date past events, processes, formations, and fossil organisms, geologists employ a variety of techniques. These include some that establish a relative chronology in which occurrences can be placed in the correct sequence relative to one another or to some known succession of events.

Radiometric dating and certain other approaches are used to provide absolute chronologies in terms of years before the present. The two approaches are often complementary, as when a sequence of occurrences in one context can be correlated with an absolute chronlogy elsewhere.

In the midth century, researchers claimed they could tell the sex of an individual just by looking at their disembodied brain. But a new study finds that human brains do not fit neatly into.

Computer Hardware Guide Software is the language of a computer. And like human language, there are many different computer languages. Essentially, computer software can be divided into three main groups depending on their use and application. These are system software or operating system referred simply as the OS, application software and programming languages.

Usually most of us interact with a computer using application software. System software or operating system is the software used by the computer to translate inputs from various sources into a language which a machine can understand. Basically, the OS coordinates the different hardware components of a computer.

There are many OS in the market. The most popular Os are from the stable of Microsoft. We have all heard, used and wondered at the Windows software, which is an OS.

See Article History Measurement system, any of the systems used in the process of associating numbers with physical quantities and phenomena. Although the concept of weights and measures today includes such factors as temperature, luminosity, pressure, and electric current , it once consisted of only four basic measurements: The last three are, of course, closely related. Basic to the whole idea of weights and measures are the concepts of uniformity, units , and standards.

Uniformity, the essence of any system of weights and measures, requires accurate, reliable standards of mass and length and agreed-on units. A unit is the name of a quantity, such as kilogram or pound.

Scientific method[ change change source ] Today, “science” usually refers to a way of pursuing knowledge , not just the knowledge itself. It is mainly about the phenomena of the material world. And over the course of the 19th century, the word “science” became increasingly associated with the scientific method itself, as a way to study the natural world, including physics , chemistry , geology and biology.

It was in the 19th century also that the term scientist was created by William Whewell. He meant it to distinguish those who sought knowledge on nature from those who sought other types of knowledge. The main features of the scientific method are: Scientists identify a question or a problem about nature. Some problems are simple, such as “how many legs do flies have? They work at it, collecting facts.

About the Different Types of Flirting By: Erickson – Updated April 27, For many people, flirting is not a science to be studied, but a basic practice everyone engages in when dealing with an object of attraction. Perhaps the flirting is innocent and subtle, with few intentions beyond enhancing your likability. However, flirting can also bridge the gap between a casual encounter and the admittance of desire. Often the variety of mannerisms and behaviors engaged during the flirtation demonstrates what type of relationship each person craves.

Acknowledgements Introduction his document discusses the way radiometric dating and stratigraphic principles are used to establish the conventional geological time scale. It is not about the theory behind radiometric dating methods, it is about their application, and it therefore assumes the reader has some familiarity with the technique already refer to “Other Sources” for more information.

As an example of how they are used, radiometric dates from geologically simple, fossiliferous Cretaceous rocks in western North America are compared to the geological time scale. To get to that point, there is also a historical discussion and description of non-radiometric dating methods. A common form of criticism is to cite geologically complicated situations where the application of radiometric dating is very challenging.

Potassium-argon dating, Argon-argon dating, Carbon (or Radiocarbon), and Uranium series. All of these methods measure the amount of radioactive decay of chemical elements; the decay occurs in a consistent manner, like a clock, over long periods of time.

No one quite knows how the sleek feline made its way to American shores during the late 19th century. However, thanks to its sociable nature, lithe body, and dark-tipped creamy coat, the Siamese became one of the country’s most beloved cat breeds. Currently, it is the 12th most popular kitty in the U. Curious to learn more? Impress ailurophiles with these 13 bits of trivia about the blue-eyed beauties.

Some people say the cats were the pets of royalty, while others believe they were raised by Buddhist monks. This suggests that the Siamese is a very old breed—even if we don’t quite know where it came from. Cat lovers brought the Siamese to America in the late 19th century, but there are mixed reports about when—and how—it traveled across the pond.

Some say the Siamese first appeared in the U.

How do scientists find the age of planets date samples or planetary time relative age and absolute age? We have rocks from the Moon brought back , meteorites, and rocks that we know came from Mars. We can then use radioactive age dating in order to date the ages of the surfaces when the rocks first formed, i.

We also have meteorites from asteroids and can date them, too. These are the surfaces that we can get absolute ages for.

Search Share Researchers have identified several structural differences between the brains of men and women, but it’s impossible to tell the sex of an individual based solely on MRI images of the brain like the one above. Indeed, all of our brains seem to share a patchwork of forms; some that are more common in males, others that are more common in females, and some that are common to both. The findings could change how scientists study the brain and even how society defines gender.

Some modest disparities have been reported: On average, for example, men tend to have a larger amygdala, a region associated with emotion. So in the new study, researchers led by Daphna Joel, a behavioral neuroscientist at Tel Aviv University in Israel, tried to be as comprehensive as possible. Using existing sets of MRI brain images, they measured the volume of gray matter the dark, knobby tissue that contains the core of nerve cells and white matter the bundles of nerve fibers that transmit signals around the nervous system in the brains of more than individuals.

They also studied data from diffusion tensor imaging, which shows how tracts of white matter extend throughout the brain, connecting different regions. The team found a few structural differences between men and women. The left hippocampus, for example, an area of the brain associated with memory, was usually larger in men than in women. In each region, however, there was significant overlap between males and females; some women had a larger or more male-typical left hippocampus, for example, while the hippocampus of some men was smaller than that of the average female.

The male end zone contained features more typical of males, and the female end zone contained the version of the same structures more often seen in females. Then, the team scored every individual region-by-region to find out where they fell on that male-to-female continuum. So how to explain the idea that males and females seem to behave differently?
