Weathering of Rocks

It is the process of breaking rocks into pieces.

• erosion

• flooding

• runoff

• weathering

The following are agents of weathering EXCEPT:

• plants and animals

• humans

• sunlight

• water, wind, temperature

The rocks in this picture are exposed to a higher temperature (with heat). What do you think will happen to the rocks?

• contracts

• evaporates

• expands

• sinks

What are the two main types of weathering?

• physical and electrical

• Physical and chemical

• chemical and electrical

• physical and mechanical

A type of physical weathering that takes place when water seeps through breaks and cracks, which then freezes and expands, thus eventually leading to the breaking of the rock

• Wet and dry cycles

• Root expansion

• Exfoliation

• Freeze-thaw

Chemical Weathering breaks down the rock by changing its chemical composition. Which of the following is NOT an example of chemical weathering?

• Carbonation

• Oxidation

• Abrasion

• Hydrolysis

Which is true about soil formation?

• Soil is made up only of decayed organic matter.

• The climate of a place do not affect the formation of soil.

• The process of soil formation takes about three days.

• The mixture of weathered rock and decayed organic matter, mineral fragments, and water forms soil.

• Dig burrows through the rock (e.g. rabbit, snakes, worms, etc.)

• Through waves it can carry rocks and make it break

• Can grow on rocks and cause it to break into pieces

• Blow bits of sand and small rocks that scratches the rock's surface

• Carries activities like mining, quarrying deforestation may weathered rocks
