The four basic components of the physical environment are?

The four basic components of the physical environment are: atmosphere, lithosphere, hydrosphere, and biosphere. 1. Atmosphere: It refers to the layer of gases that surround the Earth. It contains oxygen, nitrogen, carbon dioxide, and other gases that support life on Earth. The atmosphere also protects us from harmful solar radiation. 2. Lithosphere: It refers to the solid outermost layer of the Earth, which includes the crust and uppermost part of the mantle. It contains rocks, minerals, and soil that support plant and animal life. 3. Hydrosphere: It refers to all the water on Earth, including oceans, rivers, lakes, and groundwater. The hydrosphere provides a habitat for aquatic plants and animals and is an important source of food and water for humans. 4. Biosphere: It refers to all living organisms on Earth, including plants, animals, and microorganisms. The biosphere interacts with the other three components of the physical environment, as living organisms depend on the atmosphere, lithosphere, and hydrosphere for survival.
