- Q1
It is also known as the Mechanical Weathering.
Chemical Weathering
Physical Weathering
Biological Weathering
30s - Q2
The removal of rock in solution by acidic water.
Oxidation
Hydrolysis
Freeze-thaw
Solution
30s - Q3
The breakdown of rock by oxygen and water, often giving iron-rich rocks rusty-colored weather surface.
Oxidation
Freeze-thaw
Hydrolysis
Solution
30s - Q4
The breakdown of rock by acidic water to produce clay and soluble salts.
Hydrolysis
Freeze-thaw
Solution
Oxidation
30s - Q5
The penetration of the roots of the trees in the joints or cracks of the rocks in order to find moisture.
Chemical Weathering
Mechanical Weathering
Biological Weathering
Physical Weathering
30s - Q6
It occurs when water continually seeps into cracks, freezes, and expands eventually breaking the rock apart.
Solution
Expoliation
Freeze-thaw
Hydrolysis
30s - Q7
It occurs as cracks develop parallel to the land surface a consequence of the reduction in pressure during uplift and erosion.
Solution
Hydrolysis
Exfoliation
Freeze-thaw
30s - Q8
Bacteria, algae and lichens produce chemicals that help break down the rock on which they live, so they can get the nutrients that they need.

30s - Q9
This process occur more rapidly at higher temperature, so warm, damp climates are best.
