8.7A Revolution Mini Flashcard #4

Front

What causes the seasons on Earth?

Back

The tilt of Earth's axis (23.5 degrees) and its orbit around the sun cause the seasons.

Front

Why does autumn start in different months in North America and South America?

Back

Autumn starts in different months due to Earth's axial tilt and its position in orbit around the sun.

Front

What is the significance of Earth's axial tilt?

Back

Earth's axial tilt affects the angle of sunlight received, leading to seasonal changes.

Front

What happens during the equinox?

Back

During the equinox, day and night are approximately equal in length, and Earth's axis is not tilted toward or away from the sun.

Front

What is the position of Earth during the Northern Hemisphere's spring?

Back

The Northern Hemisphere experiences spring when Earth is in Position 3 in its orbit.

Front

How does the tilt of Earth affect daylight hours?

Back

The tilt of Earth causes variations in daylight hours; locations tilted toward the sun experience longer days.

Front

What is the relationship between Earth's position and seasons?

Back

Earth's position in its orbit relative to the sun determines the seasons experienced in different hemispheres.

Front

What occurs at Position 1 in Earth's orbit?

Back

At Position 1, the Northern Hemisphere has the fewest hours of daylight, and the North Pole is tilted away from the sun.

Front

What is the effect of Earth's tilt on winter in North America?

Back

In winter, North America is tilted away from the sun, resulting in shorter days and less direct sunlight.

Front

What is the difference between day and night caused by?

Back

Day and night are caused by Earth's rotation on its axis.
