Definition
The toll deposited at the edges of a glacier from a ridge.
Term
FLOOD PLAINS
Definition
This is formed by rivers through erosion. They are a wide flat area covered by waters during floods

WIND
Definition
This transfers energy to ocean waves as it moves across its surface
Term
DELTA
Definition
A landform made of sediment that is deposited where a river flows into an ocean or lake

MEANDERS
Definition
A river that flows across a wide flood plain and begins to form looplike bends
Term
WATERFALL
Definition
