40 points which characteristic is shared by extrusions, intrusions, and faults? only one all are cracks. all are igneous rocks. all cause gaps in the geologic record. all are younger than surrounding rocks.

The correct answer is - All are younger than surrounding rocks.

The intrusions, extrusions, and faults all tend to be younger in comparison to the surrounding rocks. The intrusions and extrusions are practically igneous rocks formed from the cooling magma into the ground (intrusions), and cooling lava on the surface (extrusions). They are newer layers of rocks than the one around them, as they appeared as a result of volcanic activity in areas where there were already preexisting rocks. The faults form at places that are close to a plate boundary, and they run parallel to the plate boundary. They are basically cracks on the crust, and they are features that have formed in preexisting rocks, thus being younger than them.
