8.7A Rotation & Revolution

Front

What is rotation?

Back

Rotation is the spinning of the Earth on its axis, which takes approximately 24 hours to complete and causes day and night.

Front

What is revolution?

Back

Revolution is the movement of the Earth around the Sun, taking about 365.25 days to complete one full orbit, which results in the changing seasons.

Front

Why does the Equator receive more direct sunlight than other parts of the Earth?

Back

The Equator receives more direct sunlight because it is positioned at 0 degrees latitude, where sunlight strikes the Earth most directly throughout the year.

Front

What causes day and night on Earth?

Back

Day and night are caused by the rotation of the Earth on its axis, as different parts of the Earth are exposed to sunlight or are in shadow.

Front

What is the significance of the Earth's tilt?

Back

The Earth's tilt of approximately 23.5 degrees is significant because it affects the intensity and distribution of sunlight, leading to the seasons.

Front

What season occurs in the Northern Hemisphere when it is summer in the Southern Hemisphere?

Back

When it is summer in the Southern Hemisphere, it is winter in the Northern Hemisphere.

Front

What is the position of the Earth during the summer solstice in the Northern Hemisphere?

Back

During the summer solstice, the Northern Hemisphere is tilted towards the Sun, resulting in the longest day of the year.

Front

What is the position of the Earth during the winter solstice in the Northern Hemisphere?

Back

During the winter solstice, the Northern Hemisphere is tilted away from the Sun, resulting in the shortest day of the year.

Front

How do the seasons change throughout the year?

Back

Seasons change as the Earth revolves around the Sun and its axial tilt causes different areas to receive varying amounts of sunlight.

Front

What is the difference between the equinox and solstice?

Back

Equinoxes occur when day and night are approximately equal in length, while solstices mark the longest and shortest days of the year.
