Unit 1: Oceanography

Front

What are spring tides?

Back

Spring tides are the tides with the biggest difference between high tide and low tide, occurring when the sun, moon, and Earth are aligned.

Front

Which ocean is closest to Antarctica?

Back

The Southern Ocean is the major ocean closest to the continent of Antarctica.

Front

Why is seawater denser than freshwater?

Back

Seawater is typically denser than freshwater due to its higher salinity.

Front

Where do warm water currents begin and travel to?

Back

Warm water currents begin near the Equator and travel to the Poles.

Front

What is the average salinity of seawater?

Back

The average salinity of seawater is approximately 35 parts per thousand (ppt).

Front

Define oceanography.

Back

Oceanography is the study of the ocean, including its ecosystems, currents, and geology.

Front

What causes tides?

Back

Tides are caused by the gravitational pull of the moon and the sun on Earth's oceans.

Front

What are neap tides?

Back

Neap tides are tides with the smallest difference between high tide and low tide, occurring when the sun and moon are at right angles to each other.

Front

What is salinity?

Back

Salinity is the measure of the amount of salt in water, typically expressed in parts per thousand (ppt).

Front

What is the role of ocean currents?

Back

Ocean currents play a crucial role in regulating climate, distributing heat, and supporting marine life.
