Which characteristic is shared by extrusions, intrusions, and faults?

Answer 1

Intrusions, extrusions of igneous rocks, and faults and gaps all share a common feature, that is, they help geologists and scientists in determining the relative age of rocks. Igneous rock is produced when the lava or magma hardens

Answer 2

All are younger than the surrounding rocks.

Explanation:

• The features extrusion, intrusion and faults are the features of the surrounding rocks.
• The extrusion and intrusions are the features of the igneous rocks. The intrusion is formed when the magma is cooled down the earth surface whereas the extrusion is formed when the lava that emit out after the volcanic activity get cooled down on the surface of earth.
• The faults are formed closed to the boundary of the plate that run parallel to the boundaries of the plate. The faults are cracks that are formed on the crust these are formed on the preexisting rocks.
