Earth has 4 spheres that must work together to support life.
These spheres are the lithosphere (land), hydrosphere (water), atmosphere (air), and biosphere (living things) that interact and sustain ecosystems.
Atmosphere
A layer of gases(air)surrounding Earth, held in place by gravity
Troposphere(6-12km)
the lowest layer of the atmosphere where weather occurs and contains most of the atmosphere's mass.
Stratosphere(12-50km)
The second layer of the atmosphere above the troposphere. contains the ozone layer and protects us from harmful UV rays.
Mesosphere(50-80km)
The third layer of the atmosphere, located above the stratosphere. It burns up meteors and dust.
Thermosphere(80-40km)
The fourth layer of the atmosphere, located above the mesosphere. It absorbs lots of harmful UV rays.
Exosphere(480+km)
The outermost layer of the atmosphere, extending from the thermosphere to about 10,000 km above the Earth's surface. It’s where the atmosphere exist into space.
Biosphere
All living organisms and their interactions with their environment, including ecosystems and biomes.
Sustainability
The ability to maintain the earth’s resources so that future generations can meet their needs too.
Carbon footprint
The amount of greenhouse gases produced by human actions.
Lithosphere
Rigid outer layer of the earths crust and upper mantel compses of rock and soil.
Three types of rock
Sedimentary
Igneous
Metamorphic
Sedimentary rock
Formed from layers of sediment
Igneous rock
Formed from cooled magma or lava
Metamorphic rock
Formed form existing rock changed by heat and pressure
Hydrosphere
All the water on earth in solid, liquid or gas form
The Hydrosphere drives the water cycle
Evaporation, condensation,precipitation, collection
Transpiration
Process where plant release water vapor into thr air through their leaves
