Which event is an example of chemical weathering?

• a) rocks falling off the face of a steep cliff

• b) feldspar in granite being crushed into clay-sized particles

• c) water freezing in cracks in a roadside outcrop

• d) acid rain reacting with limestone bedrock

The two photographs below show dates on tombstones found in a cemetery in St. Remy, New York. The tombstones were 5 meters apart and both faced north. Tombstone A had dates cut into the rock in 1922 . Tombstone B had dates cut into the rock in 1892. Which statement best explains why the dates are more difficult to read on tombstone A than on tombstone B?

• Tombstone A is composed of minerals less resistant to weathering than tombstone B

• Tombstone A has undergone a longer period of weathering than tombstone B

• Tombstone A experienced cooler temperatures than tombstone B

• Tombstone A was exposed to less acid rain than tombstone B.

The diagram above shows four magnified block-shaped sandstone samples labeled A, B, C and D. Each sandstone sample contains quartz grains of different sizes and shapes. The quartz grains are held together by hematite cement. In which sample did the quartz grains undergo the most abrasion during erosional transport?

• A

• B

• C

• D

Which characteristic would most likely remain constant when a limestone cobble is subjected to extensive abrasion?

• shape

• mass

• volume

• composition

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.
