3 Types of Faults: Normal, Reverse and Strike-Slip - Earth How
WEBNormal faults occur when two plates, one on top of the other, slide past each other and create the fault. Reverse faults occur when one plate slides under the other, creating a vertical offset. Strike-slip faults happen when two plates move horizontally past each other.

WEBSep 9, 2024 · A normal fault is a type of fault in which lengthening, or extension, of a portion of Earth’s crust causes a block of rock above the fault to move downward relative to the block below.
What is a fault and what are the different types?
WEBnormal fault - a dip-slip fault in which the block above the fault has moved downward relative to the block below. This type of faulting occurs in response to extension and is often observed in the Western United States Basin and …
