Tides

Front

What are spring tides and when do they occur?

Back

Spring tides occur during the new moon and full moon phases, resulting in the highest high tides and the lowest low tides.

Front

How many high tides and low tides occur every 24 hours?

Back

There are 2 high tides and 2 low tides every 24 hours.

What is a neap tide and when does it occur?

Back

A neap tide creates the smallest difference between high tide and low tide and occurs during the 1st quarter and 3rd quarter moon phases.

Front

What is the difference between spring tides and neap tides?

Back

Spring tides have the greatest difference between high and low tides, occurring during new and full moons, while neap tides have the smallest difference, occurring during the 1st and 3rd quarters.

Front

How often do tides rise and fall?

Back

Tides rise and fall approximately every 12 hours due to the rotation of the Earth.

Front

What causes tides on Earth?

Back

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

Front

What is the role of the moon in tidal movements?

Back

The moon's gravitational pull creates bulges in the Earth's oceans, leading to high tides in the areas facing the moon.

Front

How does the sun affect tides?

Back

The sun also exerts a gravitational pull on Earth's oceans, contributing to tidal movements, but its effect is less than that of the moon.

Front

What is the tidal cycle?

Back

The tidal cycle refers to the regular rise and fall of sea levels, typically occurring twice a day, influenced by the positions of the moon and sun.

Front

What is the significance of the tidal range?

Back

The tidal range is the difference in height between high tide and low tide, which can vary based on the alignment of the Earth, moon, and sun.
