Weathering of Rocks

This refers to the process of breaking down or changing of a rock at its location.

• Erosion

• Weathering

• Deposition

• Rock cycle

What type of weathering occurs when water interacts with calcites in caves, creating stalagmites and stalactites?

• Mechanical weathering

• Chemical weathering

• Biological weathering

• Erosion

This type of weathering is caused by living things such as plants, animals and microbes.

• Mechanical Weathering

• Chemical Weathering

• Biological Weathering

• Erosion

Which is situation is an example of mechanical weathering?

• Water comes in contact with feldspar, forming clay minerals.

• Water interacts with calcites in caves, creating stalagmites and stalactites

• Water repeatedly hits rock surface causing a part of it to break down.

• Animals break apart rocks as they burrow underground.

Repeated freezing and thawing of water forces rocks to split in a process called ___________.

• frost wedging

• frost rooting

• frost abrasion

• frost oxidation

It is the type of weathering wherein new particles with different chemical compositions are formed from rocks.

• Mechanical weathering

• Chemical weathering

• Biological weathering

• Erosion

This type of weathering changes the shape and size of rock without affecting its original composition.

• Mechanical weathering

• Chemical weathering

• Biological weathering

• Erosion

A rock reacts with oxygen and forms rust in a process called ____________.

• abrasion

• frost wedging

• oxidation

• deposition

• All of the above

Which situation is an example of biological weathering?

• Tree roots growing in between the cracks of the rock

• Animals break apart rocks as they burrow underground.
