Presentation Transcript

1. ROTATION & REVOLUTION LO: I will distinguish between revolution and rotation; I will describe how the Earth's rotation results in day and night. Rotation: the amount of time it takes a planet to spin around on its axis one time Axis: an imaginary line running through the center of the planet Revolution: the amount of time it takes a planet to orbit around the Sun

2. Rotation The Earth rotates once every 24 hours, or one day Revolution A revolution of Earth takes one year.

3. Day & Night in the Summer Longer days in the summer is related to the tilt of the Earth's axis

4. Seasons When you look at a Globe of the Earth, you can see that the earth is tilted at an angle. When the Earth travels around the Sun, it remains tilted in the same direction. This means that sometimes the top half of the Earth is pointed towards the Sun, and sometimes it is pointed away from the sun.

6. REAL AND APPARENT MOTION Real Motion: Motion caused by the object itself moving Apparent Motion: Motion caused by the observer moving
