Which statements explain reasons why unconformities occur? check all that apply. rocks along a fault break and move. igneous rock forms at earth’s surface. rocks erode and sediment is deposited. no sediment is deposited over a long time. igneous rock forms between sedimentary layers

Rocks erode and sediment is deposited, and No sediment is deposited over a long time.

Explanation:

The most common reason for the formation of uncomformity is erosion. The times of formation of the rocks above and below the uncomformity are different when no sediment is deposited over a long time.

The rock above the uncomformity are younger than the rocks below the uncomformity. Types of uncomformity are angular uncomformity, discomformity and non comformity.

In angular discomformity  horizontal sedimentary rock layers are formed above sedimentary rock layers that are in tilted position. Discomformity lies between two horizontal sedimentary rock layers. Non comformity lies between sedimentary and igneous rock layers or metamorphic rocks.

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

community
