Answer:
Each layer has a unique chemical composition, physical state, and can impact life on Earth's surface. ... Movement in the mantle caused by variations in heat from the core, cause the plates to shift, which can cause earthquakes and volcanic eruptions.
By mid point equation, x = 2, y = 0.5, the answer is 0.5
The coolest layer is the crust. The crust is on the surface of the earth (where we are) . Inner Core
