Earth science encompasses the study of the Earth, its composition, structure, processes, and history. It's a vast field that includes disciplines like:

* Geology: The study of the Earth's solid, non-living components, including rocks, minerals, landforms, and the processes that shape them.

* Oceanography: The study of the oceans, their physical properties, chemical composition, and biological life.

* Meteorology: The study of the atmosphere, weather, and climate.

* Climatology: The study of long-term weather patterns and climate change.

* Hydrology: The study of water on Earth, including its distribution, movement, and quality.

* Soil Science: The study of soils, their properties, and their role in supporting plant life.

So, while geology is its own specific discipline, it's part of the larger field of Earth science.
