Exogenic Processes

Which of the following is not a type of Mass Wasting?

• Slides

• Falls

• Solutions

• Flows

These are external processes that occur at or near the surface of the Earth.

• Rock Cycle

• Endogenic Processes

• Biogeochemical cycles

• Exogenic Processes

Which of the following is considered as a degradation process? Choose all that applies.

• Weathering

• Deposition

• Mass Wasting

• Erosion

What are the two types/processes of weathering?

• Mechanical Weathering

• Material Weathering

• Chemical Weathering

• Surface weathering

The physical breakdown and/or chemical alteration of rocks.

• Mass Wasting

• Deposition

• Weathering

• Transportation

The breaking up of large rocks into smaller fragments without changing the rock's mineral composition.

• Mechanical weathering

• Surface weathering

• Material Weathering

• Chemical weathering

This occurs in regions where temperature fluctuates above and below freezing point, resulting in a freeze-thaw cycle. Water that enters through the cracks and empty spaces of rocks expands when it freezes due to the outward force by ice.

• Unloading

• Insolation

• Frost Wedging

• Pressure release

It results from the expansion and contraction of rocks caused by the the temperature changes.

• Thermal Stress

• Frost Wedging

• Unloading

• Pressure Release

This process decomposes rocks through chemical change.

• Chemical Weathering

• Surface Weathering

• Material Weathering

• Mechanical Weathering

The process where reddish-brown rust will appear on the surface of iron-rich minerals which easily crumbles and weakens the rock.

• Carbonation

• Oxidation

• Hydrolysis

• Transporation
