Chemical and physical weathering

During chemical weathering, what can happen to the type of rock that has undergone chemical weathering?

• a new rock is produced that is larger than the original rock
• a new rock is produced that is the same as the original rock
• a new rock is produced that is different from the original rock 
• no new rock is created - it is just smaller in size

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

Rust that forms on rocks or metal because of extended exposure to oxygen is what example of chemical weathering?

• carbon dioxide (carbonic acid)
• acid rain
• oxidation
• lichens

Which type of climate will have faster chemical weathering?

• Hot and Wet
• Cold and Dry
• Hot and Cold
• Cold and Wet

What is the relationship between surface area and the rate of weathering?

• As surface area increases, the rate of weathering decreases
• As surface area increases, the rate of weathering increases
• As surface area decreases, the rate of weathering increases
• There is no relationship

What does it mean when a rock's surface area increases?

• There are more surfaces available to be weathered on the rock
• There are less surfaces available to be weathered on the rock
• The rock has weathered completely
• Surface area has nothing to do with rocks

Which of the following is an example of chemical weathering?

• Acid rain dissolving limestone
• roots breaking into concrete
• paper being ripped
• Water running over rocks

All of the following are causes of physical weathering except...

• plant growth
• wind
• acid rain
• running water

How does freezing water cause the weathering of rocks?  The freezing water—

• keeps the rocks in place
• makes the rocks last longer
• expands cracks and breaks rocks
• causes rocks to fall in landslides
