Answer 1

Exogenic Processes

Question 2

Types of Exogenic Processes

Answer 2

1. Weathering (break down of rocks)
2. Erosion and Transit (removal of rocks due to natural agents)
3. Deposition (settling or depositing to a landform)

Question 3

Types of Natural Agents

Answer 3

Gravity
Human Activity
Water
Wind

Question 4

Types of Weathering

Answer 4

Mechanical (Physical change only)
Chemical (Physical and chemical change)
Biological (Can be both)

Question 5

Types of Mechanical Weathering

Answer 5

1. Exfoliation (stripping away of rock outer layers)
2. Frost Wedging (freezing of water in cracks)
3. Root Wedging (roots grow in cracks)
4. Sand Wedging (growth of salt crystals in cracks)
5. Abrasion (scraping or wearing away)
6. Thermal Expansion (heated : expanded, cooled : contracted)

Question 6

Types of Chemical Weathering

Answer 6

1. Dissolution (dissolving)
2. Oxidation (oxygen combines with other substances, creating oxides)
3. Carbonation (carbon dioxide in contact with carbonated rocks)
4. Hydrolisis (water reacts with rock)
5. Hydration (absorption of water)
