Tides

Front

What is a tide?

Back

A tide is the regular rise and fall of sea levels caused by the gravitational forces exerted by the moon and the sun on Earth.

Front

What causes tides?

Back

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

Front

What are spring tides?

Back

Spring tides are the highest tides that occur when the Earth, moon, and sun are aligned during the new moon and full moon phases.

Front

What are neap tides?

Back

Neap tides are the lowest tides that occur when the moon is in the first or third quarter phase, resulting in less difference between high and low tides.

Front

When do spring tides occur?

Back

Spring tides occur during the new moon and full moon phases.

Front

When do neap tides occur?

Back

Neap tides occur during the first and third quarter phases of the moon.

Front

What is the difference between spring and neap tides?

Back

Spring tides are higher than normal, occurring when the sun and moon are aligned, while neap tides are lower, occurring when the sun and moon are at right angles to each other.

Front

What is the gravitational effect of the moon on tides?

Back

The moon's gravitational pull causes the water on the side of Earth facing the moon to bulge, creating a high tide.

Front

What is the gravitational effect of the sun on tides?

Back

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

How do tides affect coastal ecosystems?

Back

Tides play a crucial role in coastal ecosystems by influencing the distribution of nutrients, habitats for marine life, and the breeding cycles of various species.
