We learned about landforms created by deposition. These landforms are flat and low-lying, such as mountain streams that reach the gentle slopes of wide, flat valleys or plains at the bottom of slopes that form alluvial fans. Deposition occurs when water slows down or loses energy. Deposition also occurs as glaciers melt leaving behind piles of sediment and rock called eskers or moraines. Next we played a game where we answered questions on types of rock.
