Each sentence describes an interaction between two of Earth’s spheres. Match each sentence with the spheres that are interacting

galina1969 [7]

The answers would be the following:

Geosphere and hydrosphere - water vapor condenses on a glass.

Hydrosphere and biosphere - Grady swims in the ocean.

Biosphere and atmosphere - Lena takes a deep breath

Atmosphere and geosphere - gusty winds weather sandstone in the desert.

If you'd like to know why:

Geosphere involves the solid part of the Earth, so that would mean it involves the rocks, land, and the like.

Hydrosphere involves water, your clue there would be hydro, which means water.

Atmosphere involves the air around us, which includes winds.

Biosphere refers to the biotic components. Bio means life, so we consider living things here.

Now all those spheres interact with each other, and it is through this interactions that our world is formed and how our Earth is able to sustain life.

Taking into consideration the features of each sphere, you can see that Grady is a living organism and the ocean is made up of water.

Hence, hydrosphere and biosphere are interacting.

Lena is a living organism, and she is breathing in air.

Hence, biosphere and atmosphere are interacting.

Water vapor is made up of water, and glass is a solid found on Earth. (Not really a good example of interaction between these two spheres)

Hence, hydrosphere and geosphere are interacting. 

Lastly, gusty winds is part of the atmosphere and sandstone is a type of rock.

Hence, Geosphere and atmosphere are interacting.
