8.7A Rotation and Revolution (Pre)

The warmer weather of summer in many parts of the Northern Hemisphere is caused by the fact that during this period -

• This area receives more solar radiation 
• thid area is closer to the Sun than at other times
• The SUn emits the greatest aount of energy 
• The melting of ice raises the sea level in that area 

There would be a change in the day and night cycle on Earth if there was a change in the -

• rotation of Earth on its axis.

• orbit of Earth around the Sun.

• orbit of the Moon around Earth.

• rotation of the Sun on its axis.

Saturn rotates on its axis once approximately every 10.5 hours. From this information it can be concluded that Saturn will have which difference compared to Earth?

• On average, less than half the hours of daytime as Earth.

• More extreme seasonal temperature changes than Earth.

• A shorter path when orbiting around the Sun compared to Earth’s orbital path.

• A smaller mass that allows it to rotate faster than Earth.

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

• Increasing the speed of the rotation of Earth on its axis.

• Decreasing the time it takes Earth to make one orbit around the Sun.

• Increasing the radiation output produced each year by the Sun.

• Decreasing the number of times Earth rotates on its axis per year.

The axis on which Earth now rotates is tilted at a 23.5 degree angle. If the axis was to be changed so that it was perfectly upright like in the model, which change would be expected on Earth?

• There would no longer be periods of light and darkness.

• It would always be winter in the Southern Hemisphere.

• For every season, the length of the day would be shorter.

• There would not be the same pattern of seasonal changes in weather.
