Hydrology Test (T3) Make-Up/ RETAKE

What causes ocean acidification?

• CO2 (carbon dioxide) dissolved in the ocean, which lowers the pH.

• CO2 (carbon dioxide) filters out of the ocean, which lowers the pH.

• CO2 (carbon dioxide dissolves in the ocean which raises the pH.

• CO2 (carbon dioxide) filters out of the ocean, which raises the pH.

What property of water at different temperatures plays the biggest role in moving water up and down in the ocean?

• density

• viscosity

• turbidity

• acidity

Cleveland Ohio is farther south than London England, but London has warmer average temperatures. Which statement best explains why London has warmer temperatures than Cleveland?

• The cold air above the Gulf Stream gets blown toward Cleveland.

• The warm air above the Labrador Current gets blown towards England.

• The cool air above the Labrador Current gets blown towards Cleveland.

• The warm air above the Gulf Stream gets blown towards the shores of England.

Which statement about the relationship between the ocean and the atmosphere in MOST accurate?

• Ocean currents do not affect the atmosphere.

• The atmosphere stores more heat than the oceans.

• The oceans can hold heat better than the air.

• Ocean currents move faster than air or wind currents.

Which statement describes MOST groundwater?

• Groundwater is found in underground lakes, rivers, and streams.

• Groundwater is found in the spaces (pores) between rocks, gravel, and sand.

• Groundwater is seperate from surface water and moves in its own cycle.

• Groundwater is left below the surface for years or decades at the time.

A rural (out in the country), forested area receives a lot of rain in a short amount of time. What would most likely cause potential flooding in the area?

• If the area has a large dried out aquifer beneath it.

• If the water level in the area is below the Zone of Saturation.

• If the ground of the area is already saturated with water.

• If the ground of the area is mostly sandy soil.

When rainwater reaches the Earth's surface, it can run off the surface to water bodies or infiltrate (soak in) soil to become groundwater. Which of these surfaces would allow the MOST RUNOFF and LEAST INFILTRATION of rainwater?

• gravel

• cement

• sand

• grass

Which is MOST responsible for distributing heat energy throughout ocean waters?

• currents in ocean waters

• movement of tectonic plates beneath the ocean

• thermal vents on the ocean floor

• changes in landscape (topography) along the ocean floor

What is an important result of major ocean currents?

• transfer of heat away from the equator

• change in wind direction

• increase in ocean salinity (salt)

• increase in tectonic plate movement

How do oceans moderate (level out) global temperatures?

• Ocean currents carry warmer water away from the equator to the polar regions.

• Ocean currents carry warmer water towards the equator.

• Deep ocean water cools water at the polar regions.

• Deep ocean water warms surface water.
