weathering

Question 1

the physical breakdown (disintegration) and the chemical alteration (decomposition) of rocks

Answer 1

weathering

Question 2

the physical breakdown or disintegration of rocks at or near the surface

Answer 2

mechanical weathering

Question 3

the chemical breakdown or decomposition of rocks at or near the surface

Answer 3

chemical weathering

Question 4

5 types of physical weathering

Answer 4

1. frost wedging
2. salt crystal growth
3. sheeting or unloading
4. biological actions
5. intrusions

Question 5

the freeze-thaw action of water trapped within fractures of rocks that cause the expansion and contraction which would eventually disintegrate rocks

Answer 5

frost wedging

Question 6

a mode of weathering near coastlines where salt from seawater accumulate and grow through cracks of rocks and fracture them while growing

Answer 6

salt crystal growth

Question 7

rocks that are originally covered and are exposed are relieved from pressure causing an unloading action and expansion

Answer 7

sheeting or unloading

Question 8

organisms such as plants can burrow their roots through cracks which breaks down the rocks into pieces

Answer 8

biological actions

Question 9

the intrusions from beneath the surface induce pressure from below fracturing the rock mass on the surface

Answer 9

intrusions

Question 10

what are the 3 types of chemical weathering

Answer 10

1. solution
2. hydrolisis
3. oxidation

Question 11

a solution mixture of reactive components specific to rocks

Answer 11

solution

Question 12

chemical breakdown of minerals in rocks due to addition of water

Answer 12

hydrolysis

Question 13

chemical breakdown of minerals in rocks due to exposure to oxygen

Answer 13

oxidation
