Earth's Spheres
What is the atmosphere?
The sphere that includes all of the layers of gasses that surround the Earth
What is one process that takes place in the rock cycle?
Weathering, erosion, melting, cooling, compaction, cementation, heat, or pressure.
How does the hydrosphere and atmosphere interact?
Once water from the hydrosphere gets heated by the sun, it evaporates up into the atmosphere forming clouds. Once clouds become too full of water vapor and the temperature decreases, they will condense which brings precipitation down back to the hydrosphere
Physical change in matter from a liquid to a gas in the water cycle
Evaporation
What is the lithosphere?
The sphere that includes all non-living things (rocks, minerals, sediments ,etc.)
Which layer of the lithosphere do we live on?
Crust, Upper Mantle, Lower Mantle, Outer Core, or Inner Core
The Crust
What are the products of combustion?
carbon dioxide and water
How does the lithosphere & hydrosphere interact?
The lithosphere depends on water to break down rocks into soil through the processes of weathering and erosion.
Physical change in matter from a gas to a liquid in the water cycle.
Condensation
What is the hydrosphere?
The sphere that includes all of the water on, under or above Earth
What is the most abundant gas in the atmosphere?
Nitrogen
What is in the soil that changes nitrogen from the air into a form that plants can use?
Bacteria
How might the biosphere be affected if a harmful substance entered the lithosphere?
The biosphere may be affected because plants live in the soil which is apart of the geosphere. Plants can die due to the harmful substance in the soil. Animals can also eat organisms that live in the soil or use the soil as their habitat.
Water that falls to the earth in a solid (snow, hail) or liquid (rain) form.
Precipitation
What is the biosphere?
The sphere that includes all living things. (plants, animals, humans)
How does the movement of tectonic plates shape the surface of the earth?
They create volcanoes, earthquakes and mountains
How are human activities impacting the carbon cycle?
Burning fossil fuels puts carbon dioxide into the atmosphere.
How does the lithosphere & biosphere interact?
Geosphere is a habitat for animals, geosphere is home to plants (soil). We live on the geosphere.
The sun and gravity play a huge role in the water cycle. True or False?
True
Name one of the spheres and how people depend on it.
Geosphere- we live on the geosphere
Biosphere- friends, family, plants & animals that we eat.
Atmosphere- We breathe air in the atmosphere, protect from UV rays, protect from meteors
Hydrosphere- water we use to drink, shower, swim in.
When a volcano erupts how does the ash from the eruption interact with the hydrosphere, atmosphere and biosphere?
When the ash goes into the atmosphere, it can block sunlight from reaching Earth's surface. No sunlight means that plants can't make their own food - which affects the biosphere. Ash can also go into the water cycle through rain or falling into streams or rivers.
How are photosynthesis and cellular respiration related?
They depend on each other because one uses the products of the other.
How does Earth's atmosphere protect us? What would happen if we didn't have an atmosphere?
Our atmosphere contains the air that we breathe, our atmosphere (ozone layer) protects us from the suns harmful rays, atmosphere protects us from meteors coming to Earth's surface.
Loss of water from plant leaves through their pores and ascends up into the atmosphere
Transpiration
