Question 1: At present, glacial ice covers about.% of the Earth's surface but has covered as
much as about.% during the last Ice Age.
Question 2: Deep ocean circulation is driven primarly by.
Answer: Difference in water density.
Some models suggest that the arctic sea ice could disappear within the next
decade. If this should happen discuss some of the changes that might occur and

We recognize that the Earth system consists of several subsystems
(hydro- and cryosphere, biosphere, atmosphere and geosphere) and
that they are all connected. We also recognize that water is a unique
component of the Earth system.
Now that you have been introduced to the Earth System,
biogeochemical cycles, and the Theory of Plate Tectonics, where do
you think the salt in the salty ocean comes from? And can you explain
how the oceans salinity has remained vi
