R&R Pre-Assessment

The warmer weather of summer in many parts of the Northern Hemisphere is caused by

• this area receives more intense solar radiation

• this area is closer to the Sun than at other times

• the Sun emits the greatest amount of energy

• the melting ice raises sea level in this area

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

• rotation of the Earth on its axis

• orbit of the Earth around the Sun

• orbit of the Moon around the Earth

• rotation of the Sun on its axis

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

• On average, less that 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 that Earth

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

• Increasing the speed of Earth's rotation on its axis

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

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

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

If the axis was to be changed so that it was perfectly upright, 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 day would be shorter

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