EXOGENIC PROCESSES

Include geological phenomena and processes that originate externally to the Earth's surface.

• Exogenic Processes

• Endogenic Processes

NGSS.MS-ESS3-1

NGSS.MS-ESS3-2

Caused by the effects of changing temperature on rocks, causing the rock to break apart. The process is sometimes assisted by water.

• Chemical Weathering

• Mechanical Weathering

• Biotic Weathering

• Mass Wasting

Occurs when water continually seeps into cracks, freezes and expands, eventually breaking the rock apart. The processes induced by stresses created by the freezing of water into ice.

• Freeze-thaw

• Block disintegration

• Exfoliation

NGSS.MS-ESS2-4

Occurs as cracks develop parallel to the land surface a consequence of the reduction in pressure during uplift and erosion.

• Freeze-thaw

• Exfoliation

• Block disintegration

Tags

NGSS.MS-ESS2-2

Caused by rain water reacting with the mineral grains in rocks to form new minerals (clay) and soluble salts. These reactions occur particularly when the water is slightly acidic.

• Physical Weathering

• Chemical weathering

• Soil Erosion

• None of the above

Removal of rock in solution by acidic rainwater.

• Hydrolysis

• Solution

• Oxidation

• Carbonation

Tags

NGSS.HS-ESS2-5

The breakdown of rock by oxygen and water, often giving iron-rich rocks a rusty-coloured weathered surface.

• Oxidation

• Carbonation

• Hydrolysis

• Solution

Tags

NGSS.MS-ESS2-2

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

• Hydrolysis

• Solution

• Oxidation

• Carbonation

Tags

NGSS.MS-ESS2-2

It is the weathering or disintegration of rocks caused by living organisms.

• Biotic Weathering

• Biological Weathering

• All of the above

Also known as slope movement or mass movement, is the geomorphic process by which soil, sand, regolith, and rock move downslope typically as a solid, continuous or discontinuous mass, largely under the force of gravity, frequently with characteristics of a flow as in debris flows and mudflows.

• Mass Wasting

• Soil Erosion
