First off, let's look into how an earthquake happens:
As the plate move apart or collide given the convection current of magma, stress is built up with continuous plate movements. The pressure is then greater than the elastic strength of the rock. Rock breaks, the pressure of energy is released in the form of seismic waves. Ground vibrates, resulting in earthquake.
How it provide evidence about the layers of Earth, is that the lower the layer, the hotter it is, which then cause the convection current of magma to happen,hence affecting the lithosphere.
Hope it helps!
Tectonic plates are the surface of each and every thing on earth. all land forms rest upon them. When the plates shift, so does everything above it. But one thing is that you can barely notice it, approx. 1 inch year
TRUE. Irrigation can lead to deforestation.
The major impact for the population to inhabit those areas most likely experience high water temperatures, steam coming from the ground, and occasional shakes from the ground. Hope this helps :)
