Which feature forms at earth's surface from the cooling of lava? Extrusion fault intrusion unconformity

The correct answer is: extrusion.

There are three types of rocks that form when lava cools:

• Extrusive or volcanic rocks-form at the crust's surface as a result of volcanic activity,

• Intrusive, or plutonic rocks-form underneath the Earth's surface (magma flows into underground tunnels),

• Hypabassal, or subvolcanic rock - from magma that has solidified at a shallow depth of the volcano.
