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.

What is weathering?

• occurs when the eroded materials are dropped or laid down

• fragments of weathering rocks

• the process by which rock materials are broken down by the action of physical and chemical process

• the process by which wind, water, ice or gravity transport weathered materials from one location to another

What geologic process is happening to the rock in this picture?

• The rock is being physically weathered by the tree roots

• The rock is being chemically weathered by the tree roots

• The rock is being eroded by the tree roots

• The rock is being deposited by the tree roots

What geologic process happens when a delta forms as a river is emptied into the ocean?

• the sediment's composition is being changed by oxidation

• the sediment is being eroded by the river and deposited into the ocean
