Cover ground is a term used to describe the process of preparing an area of land for use. This can be done in a variety of ways, such as paving, roving, and sodding. Paving involves laying down a flat surface, such as asphalt or concrete, to create a hard, durable surface. Roving involves spreading a layer of gravel or other material over the ground to create a more even surface. Sodding involves laying down a layer of grass or other vegetation to create a softer, more natural surface. All of these processes are used to cover ground and make it suitable for use.
