Spheres
Which sphere includes all living things on Earth?
Which layer of Earth is the thin, solid outermost layer where we live?
Crust
What type of rock forms when molten rock (magma or lava) cools and hardens?
Igneous Rock
Identify which sphere a fish living in an ocean belongs to.
Hydrosphere
Name the sphere that contains all of Earth's water, including oceans, lakes, rivers, and groundwater.
Hydrosphere
Which layer is liquid and surrounds the inner core?
Outer Core
What type of rock forms when existing rock is changed by heat and pressure but does not melt?
Metamorphic Rock
Identify which sphere weather (like rain and wind) happens mostly in.
Atmosphere
Which sphere is the atmosphere?
The sphere that includes the layer of gases that surrounds Earth and includes oxygen and nitrogen.
Which layer is the very center of the Earth and is solid due to immense pressure?
Inner Core
What type of rock forms from pieces of other rocks, minerals, or organic material that are pressed and cemented together?
Sedimentary Rock
If a tree dies and becomes buried in mud, later forming part of a sedimentary rock, which spheres were involved in that process?
Geosphere
What is the geosphere? Give one example of something that is part of the geosphere.
Geosphere is the rocks, minerals, and landforms. Examples: varies
Which layer is the thick, solid but flowing layer between the crust and the outer core?
Mantle
What is the difference between magma and lava?
They are both melted rock, magma is found below the surface and lava is on top of the surface.
Which layer of Earth would you find magma?
Magma could be found in the mantle or the crust. Once it is on top of the crust, it then becomes lava.
Give one component (example) for each sphere: biosphere, hydrosphere, atmosphere, and geosphere.
Biosphere: plants/animals; Hydrosphere: ocean/river; Atmosphere: air/gases; Geosphere: rocks/soil.
What happens to the temperature and pressure as you go deeper into the Earth?
Temperature and pressuure increases and gets hotter
Explain briefly how a sedimentary rock can become a metamorphic rock.
Sedimentary rock gets pushed deeper into the Earth and is under extreme heat and pressure to change form.
Explain which type of the rock cycle can help the Biosphere?
Rock can be weathered into sediment and become part of the soil. Soil helps plants grow and can provide habitats for animals.
