EXOGENIC PROCESSES

Are the processes that take place at near the earth surface. They are responsible for degradation and sculpting the earth surface.

Exogenic processes

Is the process of breaking rocks into smaller pieces. It happens in the same place where the rock is found.

Weathering

Rocks break but do not change what they are made of. Caused by heat, cold, water freezing, and plant roots.

Physical/mechanical weathering

Rocks expand and are fractured when exposed to high temperature.

Temperature

When water accumulates in the crack and that point freezes, the ice expand and breaks the rock apart.

Frost wedging

The breakdown of rocks is caused by impact and friction.

Abrasion

The roots grow causing penetration into the crack

Organic activity

Is the process of breaking down rock through chemical change.

Chemical weathering

It occurs in specific minerals which are dissolve in water.

Dissolution

Rock forming mineral react with water and form different clay mineral.

Hydrolysis

It is the response of oxygen with minerals

Oxidation

Rocks cracking when water freezes insde

Mechanical weathering

Limestone dissolving in rainwater

Chemical weathering

It is the process of moving broken rocks and soil from one place to another. Those rock particles are carried away by the wind, water, ice, and gravity.

Erosion

It is the movement of sediment downslope under the influence of gravity

Mass wasting

A sudden, rapid, and destructive downward movement of detached rock fragments or boulders plunging from a steep cliff or slope due to gravity.

Rocks falls

Is the movement of rock, soil, or debris down a slope due to gravity

Landslide

is a moving mass of loose mud, sand, soil, rock, and water that travels down a slope under the influence of gravity.

Debris and mud flow

Is the process in which the weathered materials carried out by erosion settle down in a particular position

Deposition
