Waves - When waves wash up onto the sand and wash back down again, they rub against rocks. Overtime, these rocks break down and turn into pebbles called sand. The sand is dragged back down into the water when the waves wash back in. This form of erosion carries sand and rock fragments different places

Glaciers - As glaciers move gradually across the land they pick up loose materials and rocks. These rocks grind mountain walls and valleys, since they are wedged in between the glacier and ground. This form of erosion moves rocks and material to different places. This process takes lots of time

This is a weathered down rock. It was weathered down by a natural force such as wind

Running water is flowing down a hill. It is carrying sediments which is erosion

This plant is growing into the rock. It is breaking it up gradually which is a form of weathering

This stream is carrying sediments to different places which a form of erosion
