Match the term in column 1 to the characteristics in column 2. Column 1:
Mass wasting
Heating and cooling
Dust bowl
Oxidation

Column 2:
Severe farmland erosion
Type of physical weathering
Type of chemical weathering
Landslides or other collapses

a) Mass wasting  - 4) Landslides or other collapses

b) Heating and cooling - 2) Type of physical weathering

c) Dust bowl  - 1) Severe farmland erosion

d) Oxidation - 3) Type of chemical weathering

Explanation:

a) Mass wasting is defined as the slope movement which causes the downslope of soil, sand, and rock under the influence of the force of gravity. So, mass wasting causes landslides and other collapses due to slope movement.

b) Heating and cooling or temperature changes is a type of physical weathering. Rocks expand at high temperatures (Hot) and contracts at lower temperature (Cool).

c) Dust bowl : When grasses in farmlands are not tightly rooted, the eroding soil led to massive dust bowl and blow the grasses in the farmlands.

d) Oxidation is a type of chemical weathering. Oxidation is defined as the reaction of a substance with oxygen, when oxygen reacts with rocks and soil, it forms oxides which result in weathering.      

Hence, the correct answer is:

a) Mass wasting  - 4) Landslides or other collapses

b) Heating and cooling - 2) Type of physical weathering

c) Dust bowl  - 1) Severe farmland erosion

d) Oxidation - 3) Type of chemical weathering
