Retest Unit 7: Tides and Seasons

Front

What are Neap Tides?

Back

Neap tides are tides that are weaker than normal, occurring when the Moon is at the 1st or last quarter phase, and the gravitational forces of the Sun and Moon interfere with each other.

Front

When do Neap Tides occur?

Back

Neap tides occur when the Moon is in positions B and D (1st or last quarter phase).

Front

What causes tides on Earth?

Back

Tides are caused by the gravitational pull of the Moon and the Sun on Earth's oceans.

Front

What season is experienced in the southern hemisphere during position C?

Back

Winter.

Front

What is the axis of rotation?

Back

The axis of rotation is an imaginary line that passes through the North and South Poles of the Earth, around which the Earth rotates.

Front

What does the rotation of the Earth create?

Back

The rotation of the Earth creates a day.

Front

What are Spring Tides?

Back

Spring tides are tides that are stronger than normal, occurring during the full moon and new moon phases when the Sun, Moon, and Earth are aligned.

Front

What is the difference between Neap Tides and Spring Tides?

Back

Neap tides are weaker and occur during the 1st and last quarter phases of the Moon, while Spring tides are stronger and occur during the full and new moon phases.

Front

How often do tides occur?

Back

Tides typically occur twice a day, with two high tides and two low tides.

Front

What is the role of the Sun in tides?

Back

The Sun's gravitational pull also affects tides, but its effect is less than that of the Moon.
