Earth's Spheres
This sphere includes the crust, mantle, and core, and is defined as all the rock material from the outer surface to Earth's center.
What is the Geosphere?
The transfer of energy as light through space or transparent objects.
What is radiation?
The atmosphere makes the sky appear blue by doing this to sunlight.
What is scattering sunlight?
This hot, middle rock layer is about 2,900 km thick and made of molten rock called magma.
What is the mantle?
This is the main energy source for organisms and ecosystems.
What is the sun (or sunlight)?
This sphere includes all the water on, above, and below the surface of the Earth, including oceans, lakes, and water vapor.
What is the Hydrosphere?
The transfer of energy between objects that are touching. (Direct contact)
What is conduction?
The Mesosphere protects Earth by doing this.
What is burning up most meteors?
This innermost layer of the geosphere is made of liquid iron and nickel in the outer part, and solid iron in the inner part.
What is the core?
As energy moves from one organism to another in a food web, the amount of energy does this.
What is decrease (or gets less)?
This system includes all living things, such as plants and animals.
What is the Biosphere?
The transfer of energy caused by the circulation of matter due to differences in density.
What is convection?
This gas makes up 78% of Earth's atmosphere.
What is nitrogen?
This layer is Earth's thin, cool, and rigid outermost rock layer.
What is the crust?
This type of organism, like plants, uses sunlight to make food.
What is a producer?
This sphere is described as the planet's gaseous blanket, being about 100 kilometers thick.
What is the Atmosphere?
Energy flows within the Geosphere in this direction.
What is from the hot rock at the core toward the crust?
This layer of the atmosphere, closest to Earth, is the densest and where most weather happens.
What is the Troposphere?
This is where most of Earth's freshwater is found.
Where are glaciers?
Energy and matter in the biosphere are cycled from one organism to another through this.
What are food chains (or food webs)?
Interactions between water in the hydrosphere, gases in the atmosphere, and energy transferred from the sun create these on Earth.
What are weather patterns?
The global circulation of water in the oceans is driven by radiation from the sun, convection, and ____.
What is Earth's gravity?
This vital layer, found in the stratosphere, absorbs harmful UV radiation and heats that layer.
What is the ozone layer?
This percentage of the water in the hydrosphere is freshwater.
What is 3%?
Scientists use this controlled environment to observe how energy flows and matter cycles between the spheres.
What is Biosphere 2?
