This ancient civilization kept the earliest written records of ocean voyages. It is origin of the famous ancient story The "Odyssey"! 

Who were the Greeks?

100

Earth’s rigid outer layer, broken into plates, is called this.

What is the lithosphere?

100

The layer where temperature drops rapidly with depth.

What is the thermocline?

100

Winds blow from high-pressure to low-pressure areas because of differences in this.

What is density?

100

This dissolved gas is essential for respiration but has low solubility in warm water.

What is oxygen?

200

This explorer led the first expedition to circumnavigate the globe.

Who was Ferdinand Magellan?

200

New seafloor is created at this type of boundary.

What is a divergent boundary?

200

The total amount of dissolved salts in water.

What is salinity?

200

This effect causes moving air and water to curve due to Earth’s rotation.

What is the Coriolis effect?

200

Sediments originating from land are called this.

What are terrigenous sediments?

300

This 19th-century expedition is considered the foundation of modern oceanography.

What is the Challenger Expedition?

300

The process where one plate sinks beneath another.

What is subduction?

300

The three major density layers of the ocean are surface, pycnocline, and this one.

What is the deep zone?

300

The rising of deep, cold, nutrient-rich water to the surface.

What is upwelling?

300

Microscopic shells are collectively known as this.

What is ooze?

400

This technology, developed during WWII, revolutionized the mapping of the seafloor.

What is sonar?

400

This hypothesis, proposed by Alfred Wegener, suggested continents once formed a supercontinent.

What is continental drift?

400

Water is called the “universal solvent” because of this molecular property.

What is polarity?

400

Three major atmospheric circulation cells exist in each hemisphere: Hadley, Ferrel, and this one.

What is the Polar cell?

400

This process decreases seawater salinity by adding freshwater from ice melt or rainfall.

What is dilution?

500

He is known as the “Father of Physical Oceanography.”

Who is Matthew Maury?

500

This asthenosphere process drives plate movement.

What are convection currents?

500

This process increases salinity in surface waters.

What is evaporation?

500

This boundary between two air masses of different temperatures and densities often drives storm formation and influences global wind patterns.

What is a front?

500

When CO₂ dissolves in seawater, it forms this compound that can lower pH.

What is carbonic acid?
