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?

  • A) The shape of continents
  • B) Uneven heating from the Sun
  • C) Moon's gravity
  • D) Earth's tilt only

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:

  • A) tidal waves
  • B) wind drifts
  • C) ocean currents
  • D) plate tectonics

C- ocean currents

Name two factors that affect water density and therefore deep ocean current

Temperature and Salinity

200

Multiple choice: What is one way global wind patterns affect Earth's climate?

  • A) Keep temperatures the same
  • B) Move heat from the equator toward the poles
  • C) Stop clouds from forming near the ocean
  • D) Blow air into space
B- move heat from the equator toward the poles
200

Multiple choice In North America, winds tend to move from the ______ due to Coriolis effect and Earth's rotation.

  • A) east
  • B) north
  • C) south
  • D) west

D- West

Multiple choice: Which two processes primarily start surface ocean currents?

  • A) Wind on the surface and variation in water temperature and density
  • B) Tides and continental drift
  • C) Plate movement and earthquakes
  • D) Moon phases and solar flares

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).

300

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.

300

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

  1. What causes prevailing winds to curve to the right in the Northern Hemisphere and to the left in the Southern Hemisphere?
  • A Coriolis effect
  • B law of gravity
  • C ionosphere
  • D polar air masses

A- Coriolis effect

400

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.

400

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

  1.  Multiple choice: A student’s model shows the Sun heating the equator more than the poles. Which result best matches this model?

  • A Warm air and water rise and move away from the equator, creating wind and ocean currents.
  • B Cold water moves from the equator to the poles, creating latitudinal lines.
  • C Heat moves evenly across the Earth, creating longitudinal lines.
  • D Ocean currents stop when the weather changes.
  • A Warm air and water rise and move away from the equator, creating wind and ocean currents.
400

When sea ice forms near the poles, what happens to the remaining water that helps drive density currents?

  • A It becomes less salty and rises.
  • B It leaves salt behind and becomes saltier and denser.
  • C It evaporates immediately.
  • D It turns into freshwater.
  • B It leaves salt behind and becomes saltier and denser.
