GMS6 (MMS6) Watersheds Review

David is planning a kayaking trip and wants to follow the Potomac River all the way to where it drains. Into what body of water will David end his journey?

• The Chesapeake Bay

• The Gulf of Mexico

• Lake Michigan

• The Atlantic Ocean

How does the increasing slope impact the speed of water flow within the watershed?

• Increasing the slope increases the speed of water flow.

• Increasing the slope decreases the speed of water flow.

• The slope has no effect on the speed of water flow.

• The speed of water flow is only affected by rainfall, not slope.

Suppose Luna lives in the mountains far away from any water. How could chemicals in her yard harm the bay or ocean?

• Chemicals can travel through rivers and streams to reach the bay or ocean.

• Chemicals will stay in your yard and not move anywhere.

• Chemicals will evaporate and disappear.

• Chemicals will only affect the local plants.

Emma is curious about why the ocean is salty. She learns that the ocean gets its salt content from (select two):

• Rainwater dissolving minerals from rocks and carrying them to the sea

• Salt being directly produced in the ocean

• Underwater vents adding dissolved salts at mid-ocean ridges.

• Plants adding salt to the ocean

Nora is researching how much of the Earth’s water is actually available for people to drink (not frozen). What percent of the Earth’s water can be readily used for drinking?

• 1%

• 10%

• 25%

• 50%

What % of the Earth’s water is found in rivers and lakes?

• 1% of 2%

• 10% of 2%

• 50% of 2%

• 0.01% of 2%

Harper is studying blue crabs in a coastal estuary. She notices that the blue crabs only lay eggs in certain areas of the estuary. Which statement best connects salinity and the blue crab?

• The blue crab will only lay eggs in certain salinities.

• The blue crab is a species found in many aquatic environments.

• Density is a property of water that changes with temperature.

• Salinity is measured in parts per thousand.

Scarlett is studying the Chesapeake Bay and notices that the salinity levels are changing. How could this affect the plants and animals that live there?

• Changing the types of species that can survive in the water.

• Increasing the amount of sunlight in the water.

• Making the water colder.

• Reducing the amount of oxygen in the air.

Liam is studying the blue crab population in the Chesapeake Bay. He observes that the salinity of the bay has recently decreased. Based on this change, what effect would Liam most likely expect on the blue crab population?

• Increase the population

• Decrease the population

• Have no effect on the population

• Cause the population to migrate
