100

This ocean is the largest on Earth, containing 80% of all ocean water.

What is the Pacific Ocean?

100

These are vast, flat, or gently sloping areas of the deep ocean floor.

What are abyssal plains?

100

This common chemical compound, also known as table salt, is the primary salt found in seawater.

What is NaCl (Sodium Chloride)?

100

These are fast-moving, large, and destructive waves usually triggered by undersea events.

What are tsunamis?

100

Tides are the rise and fall of sea levels caused by the gravitational pull of these two celestial bodies.

What are the moon and the sun?

200

This ocean gets its name from the Greek "Sea of Atlas" and has the largest drainage area from major rivers.

What is the Atlantic Ocean?

200

This shallow, submerged edge of a continent is where most coastal activity occurs.

What is the continental shelf?

200

Seawater is a dilute solution of salts caused by these two processes acting on continental rocks.

What are weathering and erosion?

200

This term describes a current that moves in a circular fashion, influenced by wind and the Coriolis effect.

What is a gyre?

200

This type of tide occurs when the Moon, Earth, and Sun are all in a line with each other.

What is a spring tide?

300

Known as the youngest ocean, it features four distinct climate zones, including monsoon and trade wind zones.

What is the Indian Ocean?

300

This 40,000-mile long mountain range is formed by plate tectonics.

What is the mid-ocean ridge?

300

While 96.5% of seawater is pure water, this percentage represents the amount of salt present.

What is 2.5%?

300

Surface currents are caused by the Earth's rotation and these types of winds.

What are prevailing winds?

300

 During a spring tide, the ocean experiences this, characterized by higher highs and lower lows.

What is the maximum tidal range?

400

This ocean surrounds Antarctica and contains the 600-mile wide Drake Passage.

What is the Southern Ocean?

400

This specific deep, narrow canyon is the deepest point in the world's oceans.

What is the Mariana Trench?

400

To make a liquid thinner or weaker by adding a solvent like water is to do this to it.

What is dilute?

400

The high point of a wave is the crest; this is the name for the low point.

What is the trough?

400

This type of tide occurs during the 1st and 3rd quarter moon phases.

What is a neap tide?

500

Both the Southern and this smallest ocean experience the "midnight sun" in summer and continual darkness in winter.

What is the Arctic Ocean?

500

The oceanic crust is primarily made of this type of volcanic rock, which is then covered by layers of sediment.

What is basalt?

500

Besides rock particles and marine organisms, the sediment on the ocean floor includes materials formed by these.

What are chemical reactions?

500

This effect, caused by Earth's rotation, is what makes water move in a circular motion.

What is the Coriolis effect?

500

A neap tide results in a minimum tidal range because of this specific factor between the sun and moon.

What is the angle of the sun and moon?
