Describe how changes in the amount of ice covering Earth's surface can affect Earth's temperature.

• more ice, more reflection, cooler temperature
• more ice, less reflection, cooler temperature
• more ice, more absorption, cooler temperature
• more ice, less absorption, warmer temperature

Suppose there is a drought in this area. The level of the river drops because of it.
What else could happen here?

• The river will immediately rise again.
• The water table will rise. 
• The water table will fall. 
• A new aquifer will form.

A possible result of pumping large amounts of water from an aquifer is that……

• Farms produce fewer crops
• The aquifer cannot be recharged fast enough
• The recharge zone shrinks
• Groundwater stops being collected

As the Earth's temperature rises, the polar ice caps melt and shrink. This exposes more ocean which has low reflectivity. So more of the Sun's energy is abosorbed and the Earth's temperature goes up even more. This is an example of what?

• Positve feedback loop

• Negative feedback loop

• Equilibrium

Higher temperatures cause more evaporation which leads to more water vapor in the atmosphere. Water vapor is a greenhouse gas so will trap more heat so the atmosphere will warm more.

• Positive Feedback

• Negative Feedback

How can global warming cause sea levels to rise? Choose the best answer.

• by causing it to rain more often
• by melting glaciers and ice caps
• by increasing the number of undersea volcanic eruptions
• by creating bigger and more powerful hurricanes
