Land

Land is made up of stones, soil, and large rocks, but it isn’t the same everywhere. In some areas, it is flat, while in others it is hilly. All land-dwelling animals, including humans, live on land. Some animals dig burrows into the ground for shelter, using the land for their needs. People also rely on land for farming, building houses, and constructing roads. Additionally, plants and animals in forests that grow on land are used for various purposes.

• Land provides valuable resources like minerals, crude oil, and natural gas, making it an important resource for human life.
• To understand what land is made of, one can observe the layers of soil and rock when pits are dug, such as when a pipeline is being laid.
• Decomposing dead plants and animals results in the formation of humus, the top layer of mature soil. This layer is most commonly found in dense forests.
• Beneath this, the land contains sand, small stones, soil, and living creatures like worms and insects. Below this layer lies immature soil, along with pieces of bedrock.
• As one digs deeper, the amount of soil decreases, and more rock appears. This bottom layer is called bedrock, and it is from these rocks that the minerals in the soil come.
• Because of this, the soil in different regions can vary in colour and texture, depending on the type of bedrock underneath.
