Fault.
The fracture along blocks of crust (tectonic plates) is called a "fault" or "fault line".
Cracks in rocks of the crust are known broadly as discontinuities. If there is relative movement of the rocks on the two sides of the crack, then it is known as a fault. If there is not then it is known as a joint.
A fault-block mountain is formed by blocks of the Earth's crust moving along a fault.
What are large blocks of rock under the earth's crust?
earth crust displacement
The fracture along blocks of crust (tectonic plates) is called a "fault" or "fault line".
A fault
That's called a 'fault line'.
what are mountains formed by blocks of crust moving along a fault
normal fault
Large blocks of Earth's crust that drops down relative to other blocks, will form a rift valley (trench). The Great Rift Valley in Africa is one example.
fault block
A place where two tectonic plates meet is a fracture in the Earth.
faulting causes large blocks of the Earth's crust to drop down relative to other blocks
It is a fault.
They are called fault lines.
