Question

fragments lodged in the base of a moving glacier

1. glaciers erode (move) rock and ice, and then deposit it

downhill

• can move rocks of any _______(big boulders down to miniscule silt)
• usually happens _______over many years

1. eventually the glacier deposits (drops) its rocks

• can make glacial _________
• different rock type than what’s around them
• sometimes a big boulder in a field!

1. melting glaciers deposit all the bits of rocky material

they are carrying in a pile.

• these unsorted deposits of rock are glacial

Explanation:

For the first blank (36 first bullet): The phrase "big boulders down to miniscule silt" describes the size of rocks, so the word should be "size" (to indicate any size of rocks). For the second blank (36 second bullet): Glacial erosion and movement is a slow process, so "slowly" fits as it happens slowly over many years. For the blank in 37: Glaciers deposit rocks that can form glacial "erratics" (glacial erratics are rocks transported by glaciers and deposited in different locations, often with different rock types than the surrounding area, and can be boulders in fields).

Answer:

1. First blank: size; Second blank: slowly
2. Blank: erratics
