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>
Explanation:
Stomata are small pores found on the leaves of plants, through them occur an exchange of water and gases and <em>when moisture leaves the plants, a process called transpiration happens, this leads to a process similar to the evaporation.</em> Additionally, <em>plants release water vapor as a product of photosynthesis and help to prevent soil erosion by elevating groundwater.</em>

Explanation:
D. The European Union has a great influence on the world market.
I think the correct answer from the choices listed above is option D. The metamorphic rock that would most likely have formed at the highest temperatures and pressures would be phyllite. It <span>is a type of foliated metamorphic rock created from slate that is further metamorphosed so that very fine grained white mica achieves a preferred orientation. </span>
