Earth science is the study of the Earth and its processes. It includes various sub-disciplines such as geology, meteorology, oceanography, and environmental science.
The Earth is composed of several layers:
Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle. This movement causes earthquakes, volcanic activity, and the formation of mountains.
The Earth's atmosphere is composed of several layers:
The hydrosphere includes all the water on Earth, including oceans, lakes, rivers, and groundwater. It plays a crucial role in shaping the Earth's surface through processes such as erosion and deposition.
Environmental science focuses on the study of the environment and the impact of human activities on the Earth. It encompasses concepts such as conservation, pollution, and sustainable development.
