waves, tides, currents

Front

What is a wave?

Back

A wave is a disturbance that transfers energy through space or matter, typically characterized by oscillations or vibrations.

Front

What are tides?

Back

Tides are the daily changes in ocean water levels caused by the gravitational pull of the moon and the sun.

Front

What causes ocean currents?

Back

Ocean currents are caused by wind, the Earth's rotation, and differences in water temperature and salinity.

Front

What is a spring tide?

Back

A spring tide is a tide that occurs when the Earth, moon, and sun are aligned, resulting in higher high tides and lower low tides.

Front

What is a neap tide?

Back

A neap tide is a tide that occurs when the Earth, moon, and sun form a right angle, resulting in lower high tides and higher low tides.

Front

How often do tides occur?

Back

Tides typically occur twice a day, with two high tides and two low tides.

Front

What is the role of the moon in tides?

Back

The moon's gravitational pull is the primary force that causes tides on Earth.

Front

What percentage of the Earth's surface is covered by oceans?

Back

About 70% of the Earth's surface is covered by oceans.

Front

What is the difference between high tide and low tide?

Back

High tide is the maximum level of the ocean at a given location, while low tide is the minimum level.

Front

What is the Coriolis effect?

Back

The Coriolis effect is the deflection of moving objects, such as ocean currents, caused by the rotation of the Earth.
