The Earth’s Spheres

• Biosphere
• Hydrosphere
• Lithosphere
• Atmosphere

The biosphere is Earth’s sphere that contains all living things. Inside Earth’s biosphere, there are many biomes. Biomes are the places that the living things live. This is where the carbon cycle mostly takes place.

The hydrosphere is Earths sphere that contains all of Earth’s water in all forms. From the water in lakes and oceans to the water you drank this morning! Its all apart of earth’s hydrosphere. This is where the water cycle happens.

The lithosphere is Earth’s sphere that contains rock, soil, and sediments. The lithosphere can also be known as the geosphere. Mountains, plains, and valleys are all included in this sphere. This is where the phosphorous cycle takes place.

Finally the atmosphere. The atmosphere is simply all of the gases that surround Earth. It protects from the Sun’s radiation. This is also the sphere in which Earth’s weather occurs. This is where the nitrogen cycle mostly takes place.

In the image below, the carbon cycle is shown in all of the spheres. Factories emit carbon dioxide into the atmosphere. Plants and trees convert carbon dioxide into oxygen, which is part of the biosphere. Decomposers eat plants and animals that contain carbon dioxide and release it back into the air. This step associates the carbon cycle to the lithosphere. “Carbon can leave the soil through respiration which can carry it into rivers or the ocean, where it then enters the hydrosphere.”
