Spheres
What is the Geosphere?
All the rock and solid parts of Earth, like the crust, mantle, and core.
A landform with high elevation and steep sides.
Polar ice caps are part of what sphere?
Cryosphere
Darker soils and rocks absorb more heat during the day. At night, they give off this heat, keeping the area warm.
Geosphere and Atmosphere
97% of the Earths water is what kind of water?
Salt Water
What is the Hydrosphere?
All the water on Earth, including oceans, rivers, lakes, groundwater, and ice.
The boundary where the land meets the ocean or sea.
The Coastline
When a plant extracts nutrients from the soil, which two spheres are working together?
Geosphere and Biosphere
If a big volcano erupts, it can pollute the air for a very long time.
Geosphere and Atmosphere
1/3 of the Earths fresh water is where?
Underground
What is the Biosphere?
The part of Earth that supports life, including all living things like plants, animals, and microbes, and their environments.
What is the definition of a dune?

The land that supplies water to a river system is called what?
Watershed
What is the Atmosphere?
The layer of gases surrounding a planet, held in place by gravity, that provides air to breathe, weather, and protection from harmful radiation.
What is a large, flowing body of water that moves across the land?
A river.
What role do plants play in the water cycle?
Transpiration
A canyon is formed when rivers weather and erode the rocky surface over many years.
Geosphere and Hydrosphere
Below the surface, are layers of rock that hold water. These are called what?
Aquifers
What is the Cryosphere?
All water found in snow and ice around the world.
A landform made from sediment deposited at the mouth of a river.
Delta
All spheres are driven by what two things?
The Sun and the Earths Internal Heat.
As a cloud moves up a mountain slope, it cools and releases condensed water as rain or snow.
Scientist have discovered that deep ocean waters hide what?
Mountains, canyons, and trenches.
