MB 1st Semester (Oceanography) Review Practice Test

Front

What are tsunamis considered in terms of wave classification?

Back

Tsunamis are considered shallow water waves because they have long wavelengths.

Front

What forces primarily cause surface currents in the ocean?

Back

Surface currents are primarily caused by wind and the Coriolis effect.

Front

What is an ROV in oceanography?

Back

An ROV (Remotely Operated Vehicle) is a type of submersible research vessel that is unmanned but has a connection to the surface.

Front

What type of tide occurs with 1 high tide and 1 low tide per day?

Back

This type of tide is called a Diurnal tide.

Front

What type of sediment is typically found near land?

Back

Neritic sediment is typically found near land.

Front

Define the term 'fetch' in oceanography.

Back

Fetch refers to the distance over water that the wind blows in a single direction, influencing wave formation.

Front

What is the Coriolis effect?

Back

The Coriolis effect is the deflection of moving objects, such as air and water, caused by the rotation of the Earth.

Front

What is the difference between oceanic and neritic zones?

Back

The oceanic zone is the open ocean, while the neritic zone is the coastal area where sunlight penetrates, supporting more life.

Front

What is a semidiurnal tide?

Back

A semidiurnal tide is characterized by two high tides and two low tides each day.

Front

What is the role of gravity in ocean currents?

Back

Gravity helps to pull water downwards, influencing the movement of ocean currents and tides.
