Question

different sized rocks, pebbles, sand, clay, and other material left behind after a glacier melts is called
a morraine
till
an erete
rewatch

Explanation:

To solve this, we recall glacial geology terms:

• A moraine is a ridge of till (not the unstratified material itself).
• Till is unsorted sediment (rocks, pebbles, sand, clay) deposited directly by a melting glacier.
• An arete is a sharp mountain ridge formed by glacial erosion, not sediment.

So the material left by glacier melt is till.

Answer:

B. till (assuming the options are labeled as A. a moraine, B. till, C. an arete for clarity)
