Effects of Earth's Rotation

By Peter and Alexander

1. Temperature: As the Earth spins around, the sun is evenly shining on all parts of the earth. This creates an exact temperature on Earth at the same latitude. Other palnets such as Venus that have the same rate of spin as it's revolution. This makes it so that it is extreamly hot on one side of Venus and very cold on the other side since the sun only shines on one side of the planet.

2. Coriolis Effect: The coriolis effect is responsible for the rotation of cyclones, wind, and currents. because of this, winds rotate counter clockwise in the Northern Hemisphere and clockwise in the Southern hemisphere. If someone were to launch something into the atmosphere for say a rocket, the Earth might rotate and the rocket would land that many degrees in the direction earth rotated away from the primary target.
3.The Foucault Pendulum: As the Earth turns, the pendulum that is suspeneded above the floor swings freely. Since the Earth is turning sand or dominos are put under the pendulum to track it's progress. As the earth turns the floor moves beneath the pendulum eventually causing a domino to get knocked over or sand to get scraped in a new place. This proved the rotation of Earth and the coriolis effect.

4. What would happen if Earth stopped spinning?: Earth rotates at 1100 mph. If earth were to stop spinning, the atmosphere would continue to spin at that speed. The atmosphere would be going so fast that it would wipe out anything not anchored to earth. This would mean that people, animals, trees, and rocks would all be swept away. The effects are that temperature would be far more extreme and that the Sun's position in the sky would change.
5.Night and Day: While it seems like the sky moves above you it's actually the Earth moving. As the Earth rotates the Sun Shines on all parts of the earth except for one of the poles. While Earth is moving the Sun will eventually stop shining on one part of it since the Earth is turned away. This is what makes night.

6.Rate of Rotation:
  • Solar noon 360 degrees per 24 hours
  • When the Sun is at its highest 15 degrees per hour and 1 degree per 4 minutes.
