What external forces affect the topography of our planet?

As you know, there is a very scorching sun in the choirs. It is incredibly cold at night, you can sunbathe during the day. Snow begins to melt, melt water falls into gorges or cracks, at night the ice expands, and the mountain simply cracks. Plants, animals. It is the roots of plants that act mechanically, from animals the products of their vital activity, an example of sea corals from the skeletons of inhabitants. Wind and hurricanes form dunes and hills, which then harden. A person looking for minerals takes an indirect part in the formation of reliefs.
