Introduction to Physical Geology - Chapter 15

Weathering is the process of -

• Moving sediment from one place to another

• Dropping or leaving sediment in a location

• Breaking down rocks into sediment

An example of chemical weathering is -

• Ice wedging

• Oxidation

• Animals burrowing

• Crashing waves

Ice wedging is an example of -

• Physical weathering

• Chemical weathering

• Both physical AND chemical weathering

Which type of climate would cause the greatest rate of weathering?

• Cold and dry

• Warm and humid (wet)

• Cold and humid (wet)

• Warm and dry

What is likely to cause cracks on the sidewalk?

• ice wedging

• tree roots or plant roots growing bigger

• oxidation

• exfoliation

Which of the following is the most important agent of chemical weathering to form this cave?

• water - It can carry acid and dissolve rock

• wind - It displaces rocks

• exfoliation - New cracks give chemical reactions the chance to operate

• Erosion - Moves the rocks from one place to another

What are the two factors that affect the rate at which weathering occurs?

• climate and mass of rock

• climate and size of rock

• type of rock and size of rock

• type of rock and climate
