Earth's Tilt

The image shows the four positions of Earth as it revolves around the Sun. At which position will the number of hours of daylight be at a minimum in the Northern Hemisphere? 

• position 4
• position 3
• position 2
• position 1

Earth has seasons because its axis is tilted in the same direction as it moves around the Sun. Which position of the Earth corresponds to winter in the Northern Hemisphere?

• Position W 
• Position X
• Position Y
• Position Z

Earth has seasons because its axis is tilted in the same direction as it moves around the Sun. Which position of the Earth corresponds to summer in the Northern Hemisphere?

• Position W
• Position X
• Position Y
• Position Z

Earth has seasons because its axis is tilted in the same direction as it moves around the Sun. Which position of the Earth corresponds to fall in the Northern Hemisphere?

• Position W
• Position X
• Position Y
• Position Z

Earth has seasons because its axis is tilted in the same direction as it moves around the Sun. Which position of the Earth corresponds to spring in the Northern Hemisphere?

• Position W
• Position X
• Position Y
• Position Z

Use the diagram of the Earth with locations W, X, Y, and Z to answer the question. If the Southern Hemisphere is pointing toward the Sun, which location experiences the longest period of sunlight? 

• W
• X
• Y
• Z

Jaylin draws the orbit of Earth around the Sun. What changes in climate will Earth experience based upon Jaylin's drawing? 

• The seasons will only occur in regions around the equator. 
• The seasons will only occur in regions around the poles. 
• There will only be summer and winter on Earth. 
• There would be no seasons on Earth. 

The diagram shows the three major climate zones on Earth. The average annual temperatures vary across the three zones. Which option correctly determines the reasons for the variations in temperature among the three climate zones? 

• *changes in the position of the sun in the sky
  *Earth's revolution around the Sun
• *changes in the orbital path of the Earth  *Earth's rotation on its tilted axis
• *the Sun's rays striking Earth at different angles *the tilt of the Earth's axis
• *the increase in distance between the Sun and the Earth *changes in the angle of Earth's tilt

The image shows Earth tilted on its axis and the rays from the Sun falling on it at a particular time of the year. How do the lengths of days in both hemispheres compare on this day? 

• The length of days and nights will be equal in both hemispheres because the Sun is directly overhead at the equator. 
• The length of days and nights will be equal in both hemispheres because the Sun is directly overhead at the North Pole. 
• The days will be longer in the Northern Hemisphere than in the Southern Hemisphere because the Sun is directly above the Tropic of Cancer. 
• The days will be longer in the Southern Hemisphere than in the Northern Hemisphere because the Sun is directly above the Tropic of Capricor
