Moon Phases, Eclipses and Tides Summative

Front

What is a lunar eclipse?

Back

A lunar eclipse occurs when the Earth comes directly between the Sun and the Moon, blocking sunlight from reaching the Moon.

Front

What causes tides on Earth?

Back

The Moon is mainly responsible for the tides on Earth because it is much closer than the Sun.

What happens to tides during a new or full moon?

Back

The difference between high and low tides is greatest during a new or full moon.

Front

What is a spring tide?

Back

A spring tide is a tide that occurs when the gravitational forces of the Moon and Sun align, 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 Moon is at a right angle to the Sun, resulting in lower high tides and higher low tides.

Front

What is the position of the Earth during a full moon?

Back

During a full moon, the Earth is positioned between the Sun and the Moon.

Front

What is the effect of the Moon's gravitational pull on Earth?

Back

The Moon's gravitational pull causes the water in the oceans to bulge out, creating high tides.

Front

What is the difference between high tide and low tide?

Back

High tide is the maximum level of water, while low tide is the minimum level of water in the ocean.

Front

How often do tides occur?

Back

Tides occur approximately every 6 hours, resulting in two high tides and two low tides each day.

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 Moon's phase.
