Understanding Earth's Orbit and Seasons

What causes different seasons on Earth?

• Earth's rotation speed

• The distance between Earth and the Sun

• Earth's tilted axis

• The moon's orbit

Why are winter days shorter and cooler?

• Earth spins faster

• More clouds block the Sun

• The Sun's light hits at a shallow angle

• The Sun is farther from Earth

What happens during spring in the northern hemisphere?

• The North Pole tilts towards the Sun

• It starts to snow

• Days are much longer than nights

• Days and nights are of equal length

When it is summer in the northern hemisphere, what season is it in the southern hemisphere?

• Spring

• Summer

• Autumn

• Winter

Why are summer days warmer and longer in the northern hemisphere?

• Earth's rotation slows down

• The Sun's light is more direct

• There is less cloud cover

• The Earth is closer to the Sun

How do forests respond to spring?

• They lose leaves

• They turn brown

• They become dormant

• They grow green and lush

What measures the amount of carbon dioxide absorbed by primary producers?

• Underwater sensors

• Satellites orbiting Earth

• Weather balloons

• Ground-based observatories

As the Earth travels around the Sun, it creates a pattern that makes _____

• the months
• the years
• the seasons
• day and night

Which  of the following best describes the tilt of the earth during the spring and fall equinoxes?

• The earth is tilted away from the sun (Northern hemisphere)
• The earth is tilted neither toward or away from the sun (tilt is side to side)
• The earth is tilted toward the sun (Northern hemisphere)
• The earth is not tilted during spring and fall

What is the main reason for the seasons on Earth?

• The Earth's rotation on its axis

• The Earth's orbit around the sun

• The tilt of the Earth's axis

• The distance of the Earth from the sun
