wind is an agent of erosion which causes sheet erosion
Wind is the erosional force that forms sand dunes.

The force of winds shapes sand dunes.

The force that causes the formation of the solar system is primarily gravity. Gravity pulls particles and gases together, forming a spinning disk that eventually condenses into the Sun and planets. Other forces such as electromagnetic and nuclear forces also play a role in the formation process.
Electrostatic force is responsible for both the formation of ionic bonds and static cling. In ionic bonds, this force attracts oppositely charged ions together to form a bond. In static cling, the force causes objects with opposite electrical charges to be attracted to each other.
Gravitational force is what causes protostars to form. Gravity pulls together gas and dust in a molecular cloud, causing it to clump and collapse, eventually leading to the formation of a protostar.
Gravity doesn't just "affect" the formation of stars; it's just about the only force that CAUSES the stars to form in the first place.
It is called aeolian erosion
Sand dunes are formed by wind, which is one kind of erosion.
