Earth's Rotation, Revolution and Seasons

Front

What is Earth's rotation?

Back

Earth's rotation is the spinning of the Earth on its axis, which takes approximately 24 hours to complete, resulting in day and night.

Front

What is Earth's revolution?

Back

Earth's revolution is the movement of the Earth around the Sun, which takes about 365 days to complete, resulting in a year.

Front

What causes the seasons on Earth?

Back

The tilt of Earth's axis and its revolution around the Sun cause the seasons. When one hemisphere is tilted toward the Sun, it experiences summer, while the opposite hemisphere experiences winter.

Front

What season does the Southern Hemisphere experience when the Northern Hemisphere is in winter?

Back

The Southern Hemisphere experiences summer when the Northern Hemisphere is in winter.

Front

How long does it take for Earth to complete one revolution around the Sun?

Back

It takes approximately 365 days for Earth to complete one revolution around the Sun.

Front

What is the effect of Earth's rotation on the length of a day?

Back

Earth's rotation causes day and night, with one complete rotation taking about 24 hours.

Front

What happens to the seasons when the Northern Hemisphere is tilted toward the Sun?

Back

When the Northern Hemisphere is tilted toward the Sun, it experiences summer, while the Southern Hemisphere experiences winter.

Front

What is the relationship between Earth's tilt and the intensity of sunlight received?

Back

The tilt of Earth affects the angle at which sunlight hits the surface, influencing the intensity of sunlight and thus the temperature, leading to different seasons.

Front

What is the equator?

Back

The equator is an imaginary line that divides the Earth into the Northern and Southern Hemispheres, located equidistant from the poles.

Front

What is the significance of the solstices?

Back

Solstices mark the points in the year when the Sun is at its highest or lowest point in the sky at noon, leading to the longest and shortest days of the year.
