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.

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.

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

Rain causing erosion of a hillside.

A flower absording water through it's roots.

A bird flying through the air

water seeping into rocks and freezing, causing it to expand and break the rock apart.

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.

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

Negative Feedback Loops

Positive Feedback Loops

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

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.

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).
