Lesson 2: Weathering

Two types of weathering are:

The break down of rock material by chemical and physical process is called

• chemical weathering.

• weathering.

• mechanical weathering.

• physical weathering.

Another word for physical weathering is

• chemical weathering.

• weathering.

• mechanical weathering.

The process that causes chemical weathering is called:

• construction

• oxidation

Look the picture and choose the best answer for the picture.

• abrasion

• acid precipitation

• oxidation

What caused the changes in this rock?

• Chemical Weathering

• Physical Weathering

• Erosion

• Deposition

Stalactites and stalagmites form because of disolved rock from acid grownd water.

• true

• false

An example of chemical weathering is -

• Ice wedging

• Oxidation

• Animals burrowing

• Crashing waves
