A
True or False: Cold, salty water is usually denser and sinks, helping drive deep ocean circulation.
True
Multiple choice: What is the main cause of large-scale movement of air and surface water around Earth?
B- uneven heating from the sun
What causes a sea breeze during the daytime?
A. Cooler ocean air moves toward warmer land because the land heats faster.
B. Cooler land air moves toward warmer ocean because the ocean heats faster.
C. The Coriolis effect pushes air from sea to land.
D. The Moon’s gravity pulls air toward the ocean.
A. Cooler ocean air moves toward warmer land because the land heats faster.
Multiple choice: In the oceans, colder water sinks into deep basins while warmer water stays at the surface. This movement causes:
C- ocean currents
Name two factors that affect water density and therefore deep ocean current
Temperature and Salinity
Multiple choice: What is one way global wind patterns affect Earth's climate?
Multiple choice In North America, winds tend to move from the ______ due to Coriolis effect and Earth's rotation.
D- West
Multiple choice: Which two processes primarily start surface ocean currents?
A- wind on the surface and variation in water temperature and density
Describe how forming sea ice near the poles can change the salinity and density of surrounding seawater.
When sea ice forms, salt is left behind in the unfrozen water, increasing salinity and density so that water sinks (leading to deep water formation).
Which TWO pieces of evidence that supports the claim that unequal heating affects climate? (Pick two)
1. Higher temperatures near the equator
2. Earth rotates once per day
3. Ocean water contains salt
4. Cooler temperatures near the poles
5. Continents have different shapes
1. Higher temperatures near the equator
4. Cooler temperatures near the poles.
When does a land breeze typically occur?
A. Midday when land is hottest
B. Nighttime when land cools faster than the ocean
C. During a full moon only
D. Only near the equator
B. Nighttime when land cools faster than the ocean
A- Coriolis effect
Define a convection current in the ocean in one sentence.
A circulation pattern in fluids where warmer, less dense material rises and cooler, denser material sinks, producing a flow that transfers heat.
If Earth did not rotate, winds would move mainly north or south. Because Earth rotates, moving air is deflected. What is the name of this effect?
Coriolis Effect
Multiple choice: A student’s model shows the Sun heating the equator more than the poles. Which result best matches this model?
When sea ice forms near the poles, what happens to the remaining water that helps drive density currents?
