frost wedging splitting a rock apart
Which of these terms describes the process of acid rain wearing out limestone?
deposition
chemical weathering
physical weathering
erosion
Which of these is an example of erosion?

wind blowing away sediment
rain breaking down rock
all options are correct
In the pictures below, choose a picture that shows chemical weathering of rock.
In the pictures below, choose a picture that shows biological weathering of rock.
The formation of a cave as water mixed with carbon dioxide creates carbonic acid, which dissolves away the rock, is an example of:
mechanical weathering
chemical weathering
Sand settles on the beach after waves dropped it there. This is an example of...
weathering
erosion
deposition
the part of the erosion process in which sediment travels to a new location and is laid down or DROPPED OFF
