Describe the motion of the earth around the sun.
Speed increases the closer Earth is to the sun and decreases the farther it is from the sun.
What happens if it's summer in the northern hemisphere?
It is winter in the southern hemisphere due to the tilt of earths axis.

Large quantities of sand can be added to the beach to stabilize the shoreline. Which describes the disadvantage of this process?
It is a short-term solution.
Which is an advantage of simply using uranium as an energy source rather than using coal?
Uranium produces energy without polluting the atmosphere, while burning coal can increase the CO2 in the atmosphere.

It could cause an increase in cases of waterborne diseases.
A local government is considering whether to build a dam. Which is an advantage of building this structure?
It can create a storage place for water
Which results from unequal heating of the ocean water of earth?
Changes in the ocean current patterns
Why are ocean currents important to coastal regions?

Which statement describes the general movement of air masses?
They move from areas of high pressure to areas of low pressure.
Which most likely occurs when a fast-moving cold air mass moves into a region of warmer, moist air?
It causes heavy precipitation for short period of time
Which contributes to the formation of hurricanes during the late summer?

It could decrease the amount of possible infiltration in the area
Which can lead to the depletion of the ozone layer of Earth?
Aerosols
How is climate different from weather?
Climate is based on observations made for a reason over several years, whereas weather is based on day today observations made for a region.
Local government voted against the large-scale development of buildings and roads in the area. What could have been the motive behind their decision?
It could lead to the formation of heat islands, which may impact the microclimate in the area.
A company has several factories around the world and has decided to transition from burning fossil fuels to using alternate energy resources. How can a decrease in burning fossil fuels impact the atmosphere?
It could decrease the carbon dioxide levels of the atmosphere.
Some factories can increase the amount of thermal pollution by jumping heated water into lakes and rivers. How can this type of pollution affect aquatic environments?
It can reduce the number of aquatic species in the environment.
