SeasonsSpring Summer

Autumn Winter

Reasons For The SeasonsThere are seasons because the earth revolves around the sun and the earth’s tilted at 23.5 degrees, causing the different parts of the earth to receive different amounts of sunlight.

Key Vocabulary● Revolve: When the earth orbits

around the sun or the moon orbits around the earth

● Rotate: When the earth spins on its axis

How Does Seasons Affect Us?

How we travel changes:during winter, traveling is more dangerous and difficult with icy roads, snowstorms with strong winds, and airplane cancellations

We get days off during snowstorms(yay), but when there is too much snow, we have to help our parents shovel(oh no)!

How Does The Seasons Affect Us? (2)

Sun: ● makes up more than 99% of the

solar system● about 110 times wider than the

earth ● 1,300,000 Earth can fit in the

sun

Moon:● ¼ of the size of the earth● tide occurs mainly because of

moon’s gravity, which is ⅙ of the earth’s

● has mountains, valleys, and plain surfaces

What’s up?No person, even if she/he’s on south pole or north pole on the earth falls off from the earth because of its gravity. “Up” is not the same for everyone--where you areaffects the “up.” The sky you can see is your “up.”

Thanks for watching!
