extension
Earth science; Geology
In geology, the process of stretching the Earth's crust. Usually cracks (faults) form, and some blocks sink, forming sedimentary basins.
extrusive
Earth science; Geology
Igneous rocks that cool and solidify rapidly at or very near the Earth's surface. Also known as volcanic rocks.
fan
Earth science; Geology
A fan-shaped sedimentary deposit that forms where rapidly flowing water enters a relatively open, flat area. As water slows down, it deposits sediment and gradually builds a fan. See alluvial fan.
fault
