Answer:
Option (4)
Explanation:
Seismic P and S waves are generated during an earthquake that has the potential to propagate through the interior of the earth. P waves are also known as the primary waves and they move in a compression and extension way in their direction of propagation. S waves are shear waves. This P waves travel faster than the S waves and can travel in both solid as well as in liquid. Whereas the S wave can travel only through solids. They get absorbed when they reach the core-mantle boundary. These two waves are helpful in determining the epicenter of an earthquake by recording the arrival of these waves.
Hence, the correct answer is option (4).
There are 8 vertices in a rectangular prism. An easy way to remember that is the number of vertices on the 2 end squares when combined, as they are shared with the side faces<span />
Answer:
It is asking what type of environment was the rock formed in. For example, metamorphic rock and sedimentary rocks are formed at different levels of temperature and pressure. To solve the problem start off with trying to identify the type of rock (igneous,metamorphic, sedimentary,etc.) and then figure out what conditions those rocks form in. I hope this helps! Good luck!
