Earth's Patterns

Which model shows summer in the Southern Hemisphere?

• 
• 
• 
• 

• It iis day at Location 1 and night at Location 2

• Location 1 experiences more hours of daylight than Location 2

• Location 1 experiences night while Location 2 is experiencing day

• It is winter at Location 1 and summer at Location 2

During science class, students created this model. Why did the students shine a bright light on one side of the Earth?

• to show the seasons

• to show day and night

• to show the revolution of the Earth

• to show the earths rotation

Which position shows spring in the Northern Hemisphere?

• location A

• location B

• location C

• location D

Which diagram models a hypothetical situation in which every location on Earth would hhave 12 hours of daylight and 12 hours of darkness per day?

• 
• 
• 
• 

• Earth's orbit around the sun is not a perfect circle.

• North America has a larger landmass than South America.

• The moon has a greater pull on South America than on North America.

• Earth's axis has a 23.5 ⁰ tilt.

Which statement best describes conditions for Earth at Position 1 in the diagram?

• There are an equal number of hours of daylight and nightime in the Northern Hemisphere, and the North Pole is titled away from the sun.

• The Northern Hemisphere has the fewest hours of daylight, and Earth's axis does not tilt at this position.

• There are an equal number of hours of daylight and nightime in the Northern Hemisphere because Earth's axis is not titled in this position.

• Ther Northern Hemishphere has the fewest hours of daylight, and the North Pole is titled away from the sun.

Which of these changes would likely occur if the rate of Earth's rotation on its axis increased?

• The length of the seasons would be shorter.

• The length of the seasons would be longer.

• The length of a day would be shorter.

• The length of a day would be longer.

In which position is it winter in North America?

• Position 1, because North America receives the most direct sun

• Position 2, because North America is tilted toward the sun

• Position 3, because North America is parallel to the sun

• Position 4, because North America is titlted away from the sun

What should the student do in order to best model the cause of the day-and-night cycle?

• Spin the ball in different directions

• Tilt the ball while it is spinning

• Paint one half of the ball black and the other half white

• Shine a bright light on one side of the ball
