The four components of Earth are the atmosphere, hydrosphere, lithosphere, and biosphere.
1. Atmosphere: The atmosphere is the layer of gases that surrounds Earth. It is composed of nitrogen (78%), oxygen (21%), and trace amounts of other gases such as carbon dioxide, water vapor, and argon. The atmosphere plays a crucial role in regulating Earth's temperature, protecting the planet from harmful radiation, and providing the air we breathe.
2. Hydrosphere: The hydrosphere includes all of Earth's water in the form of oceans, rivers, lakes, glaciers, and groundwater. Water is essential for all forms of life on Earth and plays a key role in shaping the planet's surface through erosion and weathering processes.
3. Lithosphere: The lithosphere is the solid outer layer of Earth that includes the crust and upper mantle. It is divided into tectonic plates that float on the semi-fluid asthenosphere below. The lithosphere is where most geological processes, such as earthquakes, volcanic eruptions, and mountain building, occur.
4. Biosphere: The biosphere is the layer of Earth where life exists. It includes all living organisms, from microscopic bacteria to plants and animals. The biosphere interacts with the other components of Earth, shaping the environment and influencing the planet's climate and ecosystems.

1. Atmosphere: The atmosphere is the layer of gases that surrounds the Earth. It is composed of 78% nitrogen, 21% oxygen, and 1% other gases. The atmosphere protects the Earth from harmful solar radiation and helps to regulate the planet's temperature.
2. Hydrosphere: The hydrosphere is the part of the Earth that is covered by water. It includes the oceans, seas, lakes, rivers, and groundwater. The hydrosphere covers about 71% of the Earth's surface. Water is essential for life, and it plays a major role in the Earth's climate.
3. Geosphere: The geosphere is the solid part of the Earth. It is composed of the crust, the mantle, and the core. The crust is the outermost layer of the geosphere, and it is made up of rocks and minerals. The mantle is the layer of the geosphere that lies beneath the crust. It is made up of hot, molten rock. The core is the innermost layer of the geosphere. It is made up of solid iron and nickel.
4. Biosphere: The biosphere is the part of the Earth that is inhabited by living organisms. It includes the land, the oceans, and the atmosphere. The biosphere is a thin layer that surrounds the Earth, and it is only about 20 kilometers thick. The biosphere is essential for life, and it is home to a wide variety of plants, animals, and microorganisms.
