A U-shaped valley, also known as a glacial trough, is a large valley with steep sides, and with a wide, flat valley floor. It is formed, as the alternative name suggests, by glacial activity in the area (i.e. it was formed by a glacier).
A valley itself cannot cause erosion, but can be hugely affected by erosion. Usually Valley erosion is caused by glaciers, a common agent of erosion.

Piles of sediment
Some things that cause erosion is water and unsupported soil. If you are facing erosion, you can put up a retaining wall to protect your soil.
Ice, as glaciers during the ice-ages, scoured mountains and formed 'U' shaped valleys.

One characteristic that all agents of erosion have in common is movement. Water, wind, ice, and waves all cause erosion by creating friction from movement against the materials that become eroded.
1 is that gravity can push water downhill (rivers) and make valleys or canyons.
Rain, wind and sea. basically all of the eliments.
No. Wind can cause some erosion, but it cannot form valleys. Yosemite valley was formed by glaciers.
Ice, as glaciers during the ice-ages, scoured mountains and formed 'U' shaped valleys.
Through erosion a river creates valleys, waterfalls, floodplains, meanders, and ox bow lakes.
Gravity is an agent of erosion... I'm not quite sure if it is erosion. In the science textbook I have right in front of me it says and I quote, "Gravity, running water, waves, wind and glaciers are all causes, or agents, of erosion. Although it says it's an agent of erosion it doesn't say it is erosion. An agent is a "cause" of something.
