Energy source
Resource distribution
Resource of raw material
Protection from solar radiation
What form of energy is transferred out of the earth system?

Electrical Energy
Terrestrial Energy
Mechanical Energy
Suppose there is a tree deeply rooted in soil. What exchanges can be distributed by the soil to the tree?
Nutrients and Moisture
Carbon Dioxide and Nutrients
Moisture and Carbon Dioxide
Moisture, Nutrients, and Carbon Dioxide
If the heat on the molten core of a planet was exhausted, the planet is:
not habitable because it will turn water into ice in the surface
not habitable because the raw materials cannot be processed in the system
habitable because there can be another energy source than geothermal energy
habitable because the magnetic field is still present even if the heat was dissipated
If a planet has a thick atmosphere and is composed mostly of carbon dioxide, the planet cannot be habitable. Why is that so?
Air circulation is much slower
The atmospheric pressure is intolerable
Water will not form due to excessive heat
Most of life forms will suffocate in carbon dioxide
