MasteringMeteorology: Assignment 6 - Modules 7 & 8

What percentage of the Earth's surface is composed of water?

Approximately 70 percent of the Earth's surface is composed of water.

Most of the world's water is found in two locations. The first is the world's oceans. Where is the second location, the one with most of the world's freshwater?

Most of the world's freshwater is locked in the ice at the poles.

Despite the general stability of the Thermohaline Conveyor at present, future climate changes could alter the temperature and salinity dynamics of the world's oceans amidst rising sea levels, thereby leading to more extreme weather events. What do most scientists point to as the cause for the projected rise in sea level and extreme weather?

Scientists have projected higher sea levels and increases in extreme weather in the coming decades as a result of estimated future global emissions of greenhouse gases, primarily CO2.

There is one master ocean current that is also the drive belt of our weather systems. What is this current called?

The master ocean current is called the Thermohaline Conveyor.
