Earth Systems Flashcards
Atmosphere
The gases that are surrounding the earth.
Abiotic
The non-living things in a ecosystem
What are gases that make up the earths atmosphere
78% nitrogen
21% oxygen
0.94% argon
0.04% greenhouse gases
Layers of the atmosphere
- Troposphere
- Stratosphere
- Mesosphere
- Thermosphere
What is Troposphere composed of
Nitrogen, Oxygen, Argon and carbon dioxide
What is the Stratosphere composed of
Composed of ozone
What is the mesosphere composed of
where metors are found
What is the thermosphere composed of
where satellites and space shuttles are found.
What is Salinty
Rate/amount of salt
What is ground water
Water present underneath earth’s surface in rock and soil pore spaces and in the fractures of rock formations
Water vapour
- Gas form of water
- Most visible as clouds and fog
- Most abundant greenhouse gas in the atmosphere
Liquid water
- 4 billion years ago, Earths temperature decreased
- Decrease in temperature caused water vapour in atmosphere to become liquid – forming oceans on earths surface.
- Can be freshwater or saltwater (marine)
- Found as oceans, rivers, lakes and groundwater
Ice
- Solid form of water
- Has its own name – The Cryosphere
- Includes glaciers, ice caps and icebergs.
- Literally anything made from ice
Abiotic factors in the hydrosphere
- Dissolved oxygen concentration
- pH level
- Water temperature
- Turbidity (particles in water)
- Availability of sunlight.
- Nutrient concentration
- Rate of water flow
- Salinity (Rate/amount of salt)
The Biosphere
Sum of all ecosystems on Earth
Made up of the parts of earth where life exists
Can be found within all other Earth spheres
