Seasons

Which of the following best explains why the tilt of Earth on its axis creates the seasons?

• The amount of time it takes for the light to reach Earth changes a little throughout the year.

• The surface area of Earth is not constant throughout its orbit.

• The angle of sunlight varies on different parts of Earth at different times.

• The North Pole will always be pointed away from the Sun, making it cooler.

Which of the following combinations of factors is responsible for the changing seasons on Earth?

• Orbit of Earth around the Sun + rotation of Earth

• Orbit of Earth around the Sun + rotation of the Sun

• Rotation of Earth + Rotation of the Sun

• Tilt of the axis of Earth + orbit of Earth around the Sun

Which of the following would cause the seasons on Earth to change more gradually?

• Increasing the amount of time it takes Earth to orbit the Sun.

• Increasing the number of times Earth rotates on its axis.

• Decreasing the speed of the moon's orbit around the Sun.

• Decreasing the amount of energy the Sun emits per year.

The amount of sunlight that Mississippi receives each day changes throughout the year. What factors cause these changes?

• The distance between the Sun and the Earth.

• The percent of clouds in the sky throughout the year.

• The location of Earth's axis in relation to the Sun.

• The Sun's energy output and Earth's temperature over time.

The left side of the diagram illustrates the current tilt of Earth on its axis as it rotates.

If the axis of rotation of Earth were no longer tilted (shown on the right side of the diagram), what change would result?

• There would be many more days in a year.

• The Sun would no longer rise in the East.

• There would no longer be seasonal weather changes.

• The Sun would no longer set in the West.

• 23.5 degrees

• 25.3 degrees

• 32.5 degrees

• 52.3 degrees
