Everything on Earth can be catagorized into a major system. In Earth Science, these systems are called spheres. These larger spheres can be further broken down into sub-spheres and those can be broken down to more specific systems. The major spheres are the  biosphere, geosphere (lithosphere), atmosphere, hydrosphere and cryosphere.

HS-ESS2-2

The spheres are closely connected and a change in one can often result in a change in one or more of the other spheres. These are called interactions. 

HS-ESS2-2

Today we also learned about feedback loops, these are loops that either build upon themselves, or loops that self correct. These loops can have drastic impacts on the systems of the Earth.

Select two of the spheres (Bio, Geo, Hydro, Cryo and Atmo), and tell me an interaction that occurs between these two spheres. (An interaction is where one affects the other).

Describe how the interaction you picked above occurs (in detail).

Give an example of a positive feedback loop and explain how it fits the definition of a positive feedback loop.

Match the sphere to what occurs within it.

Which of the folowing is an example of the biosphere and the hydrosphere interacting?

Select two of the spheres (Bio, Geo, Hydro, Cryo and Atmo), and tell me an interaction that occurs between these two spheres. (An interaction is where one affects the other).

Describe how the interaction you picked above occurs (in detail).

Which type of feedback loop causes change to continue and builds off of itself?

Give an example of a positive feedback loop and explain how it fits the definition of a positive feedback loop.
