1. Glaciers & erosion
Glaciers can leave behind large boulders known as erratic.
Glaciers can move lots of sediments that can carve striations or grooves into rocks.

2. Glaciers & Erosion
Drift or till is all sediment that is deposited by glacial activity
Moraine: ridge or pile of boulders, gravel, sand left at the end of a glacier
Esker: sediment carried by water in channels of a glacier (outwash)

4. Running Water & Erosion
Rivers with lots of energy can move lots of sediment and even large boulders.
Fast water, large discharge, & a steep slope = high erosion
Slow water, low discharge, & gentle slope = low erosion

6. Running Water & Erosion
River meanders or bends in the river, shows how mature a river is.

7. Mass Movement & Erosion
Mass movement is the downward transportation of weathered materials by gravity.
