Study Notes
Earth's Structure
- Earth's outer layer is composed of gases like air, carbon dioxide, and nitrogen, forming the atmosphere.
- The geosphere contains the solid inner core, the liquid outer core, and the surrounding mantle.
- The hydrosphere encompasses all water on Earth, including rain, lakes, seas, and water vapor.
- The cryosphere represents the frozen portion of the hydrosphere, consisting of ice and snow.
- The biosphere encompasses all living organisms on Earth.
Systems and Energy
- A system is comprised of interconnected parts that work together.
- The Earth's system includes the atmosphere, hydrosphere, geosphere, biosphere, and cryosphere.
- Energy refers to the ability to do work.
Land and Water
- Topography describes the shape of the land.
- Major landforms include mountains, plains, and rivers.
- Groundwater is water found underground.
- Salinity refers to the total amount of salt in a body of water.
Freshwater Uses
- Freshwater is used for drinking, cleaning, and watering plants.
Coastline
