3rd Nine Weeks Review

A person changes the oil in his car and discards the old oil into a hole in the ground. What is one possible effect of this action?

• The small amount of oil will create a barrier between it and the groundwater.

• The small amount of oil will remain sealed in the hole and will not affect groundwater.

• The small amount of oil will seep through the layers of soil contaminating the groundwater.

• The small amount of oil will stop when it reaches a harder layer of soil thus not contaminating the groundwater.

Which action would MOST LIKELY reverse the trend shown in the table?

• Increasing the total weight of fish that each ship can remove from the ocean each day

• Requiring ships to return non-adult fish to the ocean so that they can grow and reproduce

• Decreasing the number of policing ships in order to lessen capacity restrictions and regulations

Humans depend upon food that comes from the ocean. Some human activities negatively impact these food supplies. Which statement provides the best evidence that human activities contribute to this impact?

• Human visitors to coral reef systems break corals growing on rocks.

• Humans catch marine fish at a faster rate than the fish are able to reproduce.

• Humans raise fish in a hatchery for commercial sale.

• Humans construct artificial reefs to attract tourists.

Which of these human activities is most likely to cause the excessive growth of phytoplankton in the world’s oceans?

• The use of chemical fertilizers that are carried by runoff into rivers

• The logging of old-growth forests, which results in erosion

• The spraying of chemical herbicides that reduce carbon dioxide in the air

• The mining of fossil fuels, which requires digging underground tunnels

Which of the following are examples of surface water pollution?

• Sewage discharged into a river.

• Trash swept into a stream from a storm drain.

• Oil leaking from a boat.

• All of the above.

Select ALL the ways humans interact with ocean systems.

• Tourism and recreation activities take place in or near the oceans.

• Oceans are a source of food.

• Goods and raw materials are transported across oceans.

• Water from oceans is used for crops.

• The oceans hold all of the United States Gold Reserve.

Select ALL the ways that humans impact the ocean.

• The moon's gravity causes earth's tidal forces.

• Human activities contribute to a warmer climate, increasing ice cap melting.

• Mermaids and humans are at war for control.

• Fish populations are impacted by human food needs.

• Boats and cruise ships create ocean currents.

Point source pollution is when the pollutants come from a single location that is easily identifiable, like a factory dumping chemicals into a river.

• True

• False

What is nonpoint source pollution?

• A type of pollution that isn't real.

• A type of pollution that only comes from animals.

• When pollutants are introduced into the environment over a large, widespread area and the source is not easily identifiable.

• When pollutants come from a single location and is easily identifiable.

These facts most closely correlate to which Scientific Theory? - Fossils of the plant Glossopteris were found across the Southern continents - Glacial deposits were found in tropical areas - Modern continents have a "jig-saw puzzle" appearance as if they could fit together in many instances

• Seafloor Spreading as proposed by Harry Hess

• Continental Drift as proposed by Alfred Wegener

• Plate Tectonics as proposed by John Nash
