Ground may refer to the Earth's surface or the Soil, a mixture of clay, sand and organic matter present on the surface of the Earth and serving as substrate for plant growth and micro-organisms development.

In the environmental context, "ground" typically refers to the solid surface of the Earth that is covered by soil, rocks, and other materials. Here are some examples:

1. Soil: This is the layer of material that covers the ground and is composed of minerals, organic matter, and microorganisms. It is essential for plant growth and supports a wide range of life.

2. Bedrock: This is the solid rock that forms the underlying structure of the Earth's crust. It is typically found below the soil and other loose materials.

3. Sediment: This is a mixture of small particles of rock, soil, and organic matter that has been eroded and transported by wind, water, or ice. It can accumulate on the ground and form features such as beaches and deltas.

4. Regolith: This is the layer of loose material that covers solid rock on the ground. It includes materials such as sand, gravel, and clay.

Other terms that are similar to "ground" in the environmental context include:

1. Subsurface: This refers to the layer of material beneath the ground surface, including soil, rock, and groundwater.

2. Geology: This is the study of the Earth's physical structure, including its rocks, minerals, and other materials that make up the ground.

3. Topography: This refers to the shape and elevation of the ground surface, including features such as hills, valleys, and mountains.

4. Pedosphere: This is the outermost layer of the Earth's crust that is affected by soil-forming processes, including both the solid ground and the soil that covers it.
