Exogenic/Endogenic Processes

Breakdown of rock material at and near Earth’s surface is known as

Gravity Induced downslope movement of rock material is known as

A process which disintegrates rocks, breaking larger blocks or outcrops of rock into smaller clasts/rocks

Decomposes rock through chemical reactions that remove ions from the original rock-forming minerals.

Decomposition and disintegration of rock matter accomplished in ways influenced by organisms is sometimes referred to as

The successive removal of outer rock sheets

is a process of erosion that happens in cold areas where ice forms. A crack in a rock can fill with water which then freezes as the temperature drops. As the ice expands, it pushes the crack apart, making it larger.

Water molecules attach to the crystalline structure of a mineral without causing a permanent change in that mineral’s composition.

Water containing dissolved salts accumulates in these spaces. when the water evaporates, the salts stay behind growing into crystals, which will wedge pieces of rocks apart.

The element releases its bond with the mineral leaving behind a substance with an altered chemical formula. This chemical union of oxygen atoms with another substance to create a new product is called ___

Materials expand or contract when subjected to changes in temperature

is the removal of great weights of rock or ice that lie on the surface.

5 types of Physical Weathering

A chemical reaction that causes mineral forming ions to dissociate and the separated ions are carried away in the water.

Common type of solution that involves carbon dioxide and water molecules reacting with, and thereby decomposing, rock material.

the breakdown of rock by acidic water to produce clay and soluble salts.

the motion of this could be witnessed directly by people.

We can only measure the movement and observe its effects over long periods of time.

The slow downslope movement of water-saturated soil

The gradual downslope motion primarily affecting a relatively thin surface layer of weathered rock particles.

Mass wasting events that consist of earth materials plummeting downward freely through the air

A type of mass movement in which much of the involved material is pulverized, and flows rapidly as an airborne density current along the Earth’s Surface.

A cohesive/semi cohesive unit of the earth material slips downslope in continuous contact with the land surface.

Are rotational slides where earth moves along a concave, curved surface.
