Unit D: Energy Flow in Global Systems

How will arctic ice melt from climate change affect exploration, scientific research and geopolitics?

The water in the oceans has travelled vast distances. It has even time spent deep below the surface of the Earth, trapped inside the mineral ringwoodite.

Did you know that too much carbon dioxide in the classroom can affect your body, and even your grades?

Humidity is an important part of life on Earth and life in space. This backgrounder explains what humidity is, how it is measured and how it affects us both mentally and physically.
