Front

What is the perigee-apogee cycle?

Back

The perigee-apogee cycle refers to the periodic variation in the distance between the Earth and the Moon, occurring approximately every 27.5 days.

Front

What causes tidal amplification?

Back

Tidal amplification occurs due to standing waves, which can increase the tidal range in certain areas.

Front

Define high slack water.

Back

High slack water is the peak of each high tide when there is no current motion.

Front

What is a reversing current?

Back

A reversing current is characterized by alternating flow, where water rushes up a bay or river with the incoming tide and drains out as the tide goes out.

Front

Where was the first Asian tidal power plant built?

Back

The first Asian tidal power plant was built in South Korea.

Front

What is a tidal bore?

Back

A tidal bore is a phenomenon where the incoming tide forms a wave that travels up a river or estuary against the current.

Front

Explain cotidal lines.

Back

Cotidal lines are lines on a map that connect points experiencing high tide at the same time.

Front

What is the significance of the tidal range?

Back

The tidal range is the vertical difference between high tide and low tide, which affects coastal ecosystems and human activities.

Front

How do the Moon's phases affect tides?

Back

The Moon's phases influence the gravitational pull on Earth, affecting the height and timing of tides.

Front

What is the role of the Sun in tidal patterns?

Back

The Sun's gravitational pull also affects tides, leading to spring tides (higher) and neap tides (lower) depending on its alignment with the Moon.
