Earth works like one big system that breaks up into subsystems. These systems include:
1. Lithosphere – contains all cold hard soil of the planet.2. Hydrosphere – all liquid and gaseous water on the planet.3. Biosphere – Contains all of the earths living objects.4. Atmosphere- All of the air in the earth systems.5. Cryosphere- All of the earth glaciers, icecaps, and icebergs.
Earth as a System
Each system of the earth works together to make the planet habitable.
Examples: Water from the hydrosphere heats to create clouds put into the atmosphere.
The atmosphere and hydrosphere makes it possible for the animals on land and in water to survive.
How They Work Together?
Each system has a group of science that goes with that system .
Biosphere has all living life so they have sciences like biology.
Lithosphere has sciences like geology. Etc.
Sciences in each system.
All living objects would die due to the lack of oxygen. Which would also kill the plants that need CO2 for photosynthesis. This would cause a domino effect on the rest of the planet.
What would happen if the earth’s systems didn’t work together?
Geoscience
● Geoscience- The study of earth.● This field of science focuses on the
atmosphere, biosphere, and other systems.
Astronomy
● Astronomy- The study of space● Astronomers study matter in outer space,
especially the positions, dimensions, distribution, motion, composition, energy, and evolution of celestial bodies and phenomena.
Cosmology
● Cosmology- The study of the universe● This field of science studies where the
universe came from and how it developed.
Meteorology
● Meteorology- Study of the atmosphere● Meteorologists study climate, weather, and
weather forecast.
Oceanography
● Oceanography- Study of the ocean.● This field of science studies the physical
and biological properties and phenomena of the sea.

subsystemsThere is 5 different subsystems. people usually are only familiar with 4 of them but there is a total of 5. each of these layers has a key role in how we live our lives. lets explore them
BiosphereBiosphere is anything to do with life, anything that is living has to interact with this subsystem.
GeosphereGeosphere is physical earth, the formation of rocks and how magma flows is all apart of Geosphere

Connection between hydrosphere and biosphere
• The connection can be seen in all ecosystems such as swamps or coral reefs!
• Amphibious animals rely on both the hydrosphere and biosphere for food and shelter
