Earth Sciences: Earth's Spheres

Earth is made up of four distinct yet connect spheres. In this video lesson, you will learn about where each sphere is found on Earth, as well as some features commonly found in each.

Earth’s Spheres (Systems)

• Geosphere (lithosphere): Solid, rocky part of Earth

• Atmosphere: Gaseous part of Earth about 10 km of the surface to hundreds of kilometers higher

• Hydrosphere: All of the water (liquid, solid, gaseous) on and within the geosphere

• Biosphere: All the areas in the geosphere, atmosphere, and hydrosphere that are inhabited by and support life

​What belongs in the Biosphere?

• ​plants

• animals

• bacteria

• fungi

• all living things

• clouds

• ​fog

• ​oxygen

• ​all the gasses

​What belongs in the Atmosphere?

​What belongs in the Geosphere?

• ​rocks

• ​soil

• ​crystals

• ​mountains

• ​magma and lava

• lakes

• ​rivers

• ​oceans

• ​rain

• ​groundwater

​What belongs in the Hydrosphere?

​What belongs in the Cryosphere?

• ​ice

• snow

• glaciers

• icebergs

• all the ice on Earth

• Earth is made of four layers.

  • Crust

  • Mantle
