Wind moves from _____-pressure areas toward _____-pressure areas?

High/Low

100

What type of current, driven mainly by wind, sits at the top 10% of ocean water?

Surface Current

100

What process turns liquid water into water vapor and adds it to the atmosphere?

Evaporation.

200

Name the process by which warm air rises and cool air sinks, creating circulation in the atmosphere.

Convection Currents

200

Besides temperature, what property of seawater affects its density and helps drive deep ocean currents?

Salinity (amount of salt in water)

200

Name the process where water vapor cools and changes back into liquid droplets forming clouds.

Condensation

300

What is the main cause of wind patterns around the globe?

The uneven heating of Earth's surface

300

Describe surface currents near the equator.

Surface currents along the equator run parallel (east-to-west) due to the Trade Winds and the absence of the Coriolis force at 0° latitude.

300

Explain how the Sun and gravity drive the movement of water from the ocean to the land and back. (One or two sentences.)

The Sun heats ocean water so it evaporates; gravity causes precipitation and runoff that return water to oceans.

400

What name is given to the steady wind that blows from the ocean toward the land during the day because land heats faster than water?

Sea breeze

400

Describe (in one or two sentences) how warm surface water and cold deep water interact in a convection current.

Warm water rises at the surface and colder water sinks below; this vertical movement helps drive circulating currents.

400

Explain runoff as it relates to the water cycle

The movement of water across the land surface into streams, rivers, and lakes, eventually back to the ocean. 

500

Explain how the Coriolis effect influences wind direction on Earth

Earth's rotation causes moving air to curve (right in NH, left in SH), altering wind direction.

500

Explain how differences in salinity and temperature combine to form the global conveyor‑belt.. Include the roles of density, sinking, and rising water.

Differences in temperature and salinity change water density; cold, salty water becomes dense and sinks, pulling surface water along and creating a global circulation (thermohaline conveyor) that moves water and heat around the planet.

500

Explain the similarities and differences between transpiration and evaporation. 

Transpiration and evaporation both transfer liquid water into atmospheric vapor. Transpiration occurs in living plants, while evaporation happens from open bodies of water.
