a force that builds up mountains and landmasses on Earth's surface; any natural process that builds up Earth's surface
The breaking down of rocks and other materials on the Earth's surface.
Processes by which rock, sand, and soil are broken down and carried away by wind, water, or other natural agents.
the sliding down of a mass of earth or rock from a mountain or cliff.
A landform made of sediment that is deposited where a river flows into an ocean or lake
Shaking and vibration at the surface of the earth resulting from underground movement along a fault plane of from volcanic activity
when wind moves sand, dust and soil from one place to another; caused the Dust Bowl;can be limited by planting trees and other plants

A type of rock that forms when particles from other rocks or the remains of plants and animals are pressed and cemented together
a type of rock that forms from the cooling of molten rock at or below the surface
A type of rock that forms from an existing rock that is changed by heat, pressure, or chemical reactions.
Sections of the Earth's crust that move due to convection currents.
a break or crack in Earth's surface. Caused by shifting and moving plates.
two plates are moving away from each other and new crust is forming from magma that rises to the Earth's surface between the two plates; example: mid-ocean ridge in the Atlantic
when plate tectonics push up against each other, forming a mountain chain
hills of sand shaped by the wind
Formed by two continental plates colliding and forcing each other upwards.
an opening in the Earth's crust caused by converging and diverging plate boundaries through which molten lava, ash, and gases are ejected.
Process in which sediment (or broken rock and sand) is laid down in new locations.
