Science TEK 5.8c Earth's Rotation
This storyboard does not have a description.
Its 9:00 am in china and just a few hours ago the sun was just below the horizon. Now it is high in the sky and is moving across the sky as time goes on. I wonder why this happens?
Well this happens due to earths rotation. You see, one side of earth is shadey, the other is in sunlight. Earth makes one rotation every 24 hours, and rotates on its axis, which is an imaginary line going through the centre of the planet vertically. so it seems its moving across the sky but it isnt.
not to scale
Here in the U.S its night time and everyone is in their beds, but in china people are just waking up. Since earth rotates we get day and night, and when its night in china its daytime in the U.S.
