A break or crack in the Earth’s crust is called a ____
A
plate
B
fault
C
fold
D
crack
Explanation: 

Detailed explanation-1: -Faults are cracks in the earth’s crust along which there is movement. These can be massive (the boundaries between the tectonic plates themselves) or very small. If tension builds up along a fault and then is suddenly released, the result is an earthquake.

Detailed explanation-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. This movement may occur rapidly, in the form of an earthquake-or may occur slowly, in the form of creep.

Detailed explanation-3: -A fault is a fracture in the Earth’s crust along which two blocks of the crust have slipped with respect to each other. Faults are divided into three main groups, depending on how they move. Normal faults occur in response to pulling or tension; the overlying block moves down the dip of the fault plane.

Detailed explanation-4: -A fault is formed in the Earth’s crust as a brittle response to stress. Generally, the movement of the tectonic plates provides the stress, and rocks at the surface break in response to this. Faults have no particular length scale.

Detailed explanation-5: -They found that while there was global cooling in Earth’s early years, the outer shell was warming at the same time, which is the most likely cause behind our planet’s crust breaking apart.
