Study Notes
Earth's Subsystems
- Earth is a complex system of interrelating physical, chemical, and biological processes.
- It is comprised of four major smaller systems known as subsystems: atmosphere, geosphere, hydrosphere, and biosphere.
Atmosphere
- Serves as the Earth's blanket.
- Composed of gases in varying amounts.
- Its relative abundance is also crucial in different parts of the Earth.
Geosphere
- Comprises of landforms like mountains and hills.
- Important because it provides the environment for all living things to live in and survive.
Hydrosphere
- Covers almost the entire Earth's surface.
- Contributes to Earth's habitable condition by absorbing and redistributing solar radiation.
- Interacts with the atmosphere during events like pouring rain and evaporating water.
Biosphere
- Interacts with the geosphere when plants draw water and nutrients from the soil.
- Interacts with the atmosphere and hydrosphere during photosynthesis.
Interactions between Subsystems
- Taal Volcano spewing gases and ashes into the air affects the atmosphere by affecting the amount of gases in the atmosphere.
- Flood is a part of geosphere and interacts with hydrosphere, while soil is a component of biosphere.
- Water availability impacts the growth of animals like cows who depend on plants for food, involving the hydrosphere and biosphere.
- Rocks undergoing weathering due to flood show an interaction between geosphere and hydrosphere.
Importance of Subsystems
- Geosphere is important because it provides the environment for all living things to live in and survive.
- Atmosphere is essential to life because it provides the gases essential to life and for organisms to perform bodily processes.
