Erosion
There are many forces that cause sediment to break down (weathering) and move (erosion). We'll go over the top 4.
1. Running Water
2. Glaciers
3. Wind
4. Waves

Running Water
Quickly moving water is the most powerful form of erosion.
Sediments get moved a pushed into each other constantly in rivers, streams, eddies and currents.
Rivers carve out "V" shaped valleys.
They can cut steep canyons like slot canyons or just regular canyons like the Grand Canyon.
Rivers are also responsible for flood plains and deltas.

Glaciers
Glaciers are permanent bodies of snow and ice that "migrate" as they melt and freeze down a mountain. As they move they can carve a trail into the mountain known as a moraine.

They can move huge boulders

Wind
Wind moves small sand grains and sometimes pebbles but has to leave behind bigger rocks. Wind also causes sand dunes to migrate.
Waves
Waves cause beaches to erode and sometimes migrate down the coast. That is called Long Shore Drift. The water is pushed at the beach at an angle. Gravity pulls the water down perpendicular to the beach. This moves the sand down the beach.
