What is one effect of upwelling in the ocean?

• Offshore oil rigs pumping oil to the surface displaces ocean water with carbon dioxide during the fracking process.

• Nutrient rich deep ocean water is brought to the surface.

• Freshwater underneath the ocean floor is brought to the surface.

• Shells and fossilized coral appears on the beach.

To represent the distribution of water on earth, a teacher filled a two liter bottle with 2000mL of water. She then made a mark at the 1944 mL point. What should be written at the 1944 mL level to distinguish the type of water at that point?

• water from glaciers and icebergs

• groundwater

• ocean water

• water from ponds, rivers, lakes and streams

How are estuaries connected to oceanic organisms?

• estuaries provide a nursery grounds for oceanic organisms

• estuaries provide sunlight for oceanic organisms

• estuaries provide primary food for oceanic organisms

• estuaries provide excess dissolved oxygen for oceanic organisms

Which best describes the characteristics of a river basin?

• the land drained by a river and its tributaries

• the land formed when rivers create estuaries and marshes

• the land at the mouth of the river where water flows into the ocean

• the land formed as a result of a river flooding

How does groundwater help to keep surface waters full?

• Groundwater is stored in aquifers where it slowly moves into riverbeds.

• Groundwater supplies are always plentiful and never disappear.

• Groundwater is taken from the ground by humans and put into lakes and rivers.

• Groundwater flows as runoff on the surface and into lakes and rivers.
