Earth's Movements and Effects Flashcard (Rotation, Revolution, Tilt)

Front

What causes the change of seasons on Earth?

Back

The tilt of the Earth's axis causes different parts of the Earth to receive varying amounts of sunlight throughout the year, leading to the change of seasons.

Front

What did ancient astronomers believe about the Earth's position in the solar system?

Back

Ancient astronomers believed that the Earth was at the center of the solar system.

Front

What shape is Earth's orbit around the sun?

Back

Earth's orbit around the sun is elliptical.

Front

What season is experienced in the Northern Hemisphere when it is tilted towards the sun?

Back

Summer.

Front

What is the longest day of the year in the Northern Hemisphere called?

Back

Summer Solstice.

Front

What is the Earth's rotation?

Back

The Earth's rotation is the spinning of the Earth on its axis, which takes approximately 24 hours to complete.

Front

What is the Earth's revolution?

Back

The Earth's revolution is the movement of the Earth around the sun, which takes about 365.25 days to complete.

Front

What is the significance of the Earth's axial tilt?

Back

The Earth's axial tilt is significant because it affects the intensity and duration of sunlight received at different latitudes, influencing climate and seasons.

Front

What happens during the Winter Solstice?

Back

During the Winter Solstice, the Northern Hemisphere is tilted away from the sun, resulting in the shortest day and longest night of the year.

Front

What is an equinox?

Back

An equinox occurs when day and night are approximately equal in length, happening twice a year during spring and autumn.
