Which answer below does NOT describe a cause of surface ocean currents?

• Continental deflection is when a current meets land and changes direction

• Global winds cause currents to flow in different directions

• Density causes cold water to rise to the surface in the ocean

• Coriolis effect causes the ocean currents to curve due to Earth’s rotation

Which answer choice correctly describes global heat convection?

• Cold air rises from the equator towards the poles, because warm air rises and cold air sinks

• Warm air rises from the equator towards the poles, because warm air rises and cold air sinks

• Cold air rises from the equator towards the poles, because cold air rises and warm air sinks

• Warm air rises from the equator towards the poles, because cold air rises and warm air sinks

• Warm currents carry warm water from the tropics toward the poles.

• Warm currents carry cold water from the tropics toward the poles.

Which argument supports the evidence from Step 3 of the investigation?

• Freshwater is rising because it has a higher albedo.

• Freshwater is rising because it is colder.

• Saltwater is sinking because its volume is increasing.

• Saltwater is sinking because it is more dense.
