Earthquakes generate compressional waves (p-waves) and shear waves (s-waves). Compared to the speed of shear waves in a given earth material, the speed of compressional waves is the fastest.
Because of this the compressional waves are the first waves to arrive on a complete record of ground shaking. They are also called P waves, which derives from this fact - P is an abbreviation for primary, first wave to arrive.<span>They typically travel at speeds between ~1 and ~14 km/sec.</span>
Answer:
The best answer to the question: The greenhouse effect is driven by the fact that greenhouse gases are:___, would be: Good absorbers of radiation at all wavelengths.
Explanation:
Under normal circumstances, the Earth receives energy from the sun and also produces a bit of its own energy. The energy that arrives from the sun is usually known as shortwave radiation, while the energy that is both absorbed by the Earth´s atmosphere, and the energy produced by Earth itself, becomes part of what is known as the longwave radiation. Greenhouse gases, like water vapor, carbon dioxide and methane trap both longwave and shortwave radiation, which should usually be expelled to a certain extent towards space, and maintain them trapped inside the atmosphere. This bouncing effect between the shield created by the gases and the lower atmosphere, should normally be controlled by the amount of atoms of gases in the higher atmosphere. However, in the greenhouse effect, what is happening is that the amount of gases is too high, and therefore they are trapping most of the radiation, both longwave and shortwave, and keeping it in, allowing the climate to warm up.
Answer:
C. One particular good or service
Explanation:
Specialization, along with the complementary concept of the division of labor, occurs when the innate inequalities of human productive output are intensified along different skills. An individual becomes economically specialized when he focuses his productive efforts on an increasingly narrow range of tasks.
Answer:The quality or state of being volcanic; volcanic activity. ... The level of power of a volcano.
Explanation:
As a result of the hot spot volcanoes of Iceland and Hawaii producing a huge amount of basalt, the nearby beaches are made of <u>black sand.</u>
<u></u>
<h3>What is the effect of Basalt on sand?</h3>
Basalt is a black volcanic rock that is commonly found around volcanoes. It has this coloration and appearance as a result of a high concentration of augite and other dark minerals.
Areas with a high concentration of basalts, such as beaches in Iceland and Hawaii, will reflect this dark hue coloration by generating black sand when combined with basalt.
