The solid layer of rock beneath the soil

Smaller earthquakes that follow a major earthquake.

Mining which involves miners removing pillars in a specific order to allow the least stress on the walls and ceiling of the mine

Rock formed from cooled magma or lava solidifies

Volcano ejecta is lava harden to form either a smooth surface or a ropy surface

The term describes the way a mineral reflects light from its surface

The logic error in which someone assumes a change in one factor caused the change in another factor only because the second change occurred after the first
