Tides

Front

What are the two types of tides experienced by most coastlines on Earth?

Back

Two high tides and two low tides.

Front

What celestial body primarily influences the tides on Earth?

Back

The Moon.

Front

How does the Earth's rotation affect tides?

Back

As the Earth rotates, different regions are pulled into the bulge created by the Moon's gravitational pull, resulting in high and low tides.

Front

What causes high tides?

Back

High tides are caused by the gravitational pull of the Moon, which creates a bulge of water on the side of the Earth facing the Moon.

Front

What is a tidal bulge?

Back

A tidal bulge is the increase in water level caused by the gravitational pull of the Moon and the Sun.

Front

How often do most coastlines experience high and low tides?

Back

Most coastlines experience high and low tides approximately every 12 hours.

Front

What is the difference between spring tides and neap tides?

Back

Spring tides occur when the Earth, Moon, and Sun are aligned, resulting in higher high tides and lower low tides. Neap tides occur when the Moon is at a right angle to the Earth-Sun line, resulting in lower high tides and higher low tides.

Front

What role does the Sun play in tidal movements?

Back

The Sun's gravitational pull also affects tides, but its influence is less than that of the Moon. It contributes to the variation in tidal heights.

Front

What is the term for the highest point of a tide?

Back

High tide.

Front

What is the term for the lowest point of a tide?

Back

Low tide.
