Which option defines Moraine?

Which option defines Moraine?

• A. A glacier created by wind erosion
• B. Edge of a glacier
• C. A lake formed by melted ice
• D. A river channel formed by runoff

Answer: (B)

A moraine is a ridge or bump of rock, gravel, and dirt carried and deposited by a moving glacier. It forms along the edges and at the ends of a glacier as the ice pushes material along and then melts, leaving the debris behind. That edge-of-glacier location is what defines a moraine, since it marks where the glacier has been and what it has left behind. This stands in contrast to features formed by wind (like dunes), by melted ice creating a lake, or by running water creating a river channel.
