Question

How fast does the crust layer move usually?

What is a fault? How big are they?

What happens when too much pressure builds up at a fault?

Answer 1

1 = 0.6 inches a year
2= A fault is a fracture or zone of fractures between two blocks of rock. Faults allow the blocks to move relative to each other. ... Earth scientists use the angle of the fault with respect to the surface (known as the dip) and the direction of slip along the fault to classify faults. And Faults may range in length from a few millimeters to thousands of kilometers
3= When too much pressure builds, massive chunks of the Earth move and release intense energy. This results in waves that travel through the Earth's outer crust to cause the shaking during an earthquake

Answer 2

A fault is a place in between two tectonic plates they are as big as the edge between two continents The crust layer moves at 0.6 inches per year if there is too much pressure at a fault i believe a volcano will appear

Step-by-step explanation:

The crust moves due to the convection currents in the earth
