EARTH'S ROTATION AND REVOLUTION: Independent Study

Your Assignment Make sure you have answered “Why do we have day and night?” and “Why do we have seasons?” under WHAT I THINK. By the end of this PowerPoint presentation, you should have the following organizers filled out: a. Rotation Foldable (left side)-You will be called out to do the “Try This”. b. Revolution Foldable-BOTH sides c. Rotation vs. Revolution venn If you are unable to find all the needed info in this presentation, you can access the internet to look for information! If you finish all work before time is up, you can fill out the “What It?” foldable, both sides. Write on the TOP of the flap, NOT on the notebook paper!!!!!

Earth’s Rotation Rotation is the spinning of the Earth on its axis. The time for one rotation is 24 hours. The speed of rotation 24,855 miles/24 hr or 1,038 miles/hr The Earth tilts at 23 degrees. Click image to view Earth’s rotation.

Earth’s Revolution A revolution technically means going around in an orbital path. A revolution occurs as the earth moves around the sun. Time for one revolution = 365 1/4 days = 8,766 hours. The speed of earth’s revolution is about 18 miles per second.

Earth’s Revolution

Earth’s Orbit The orbital path an object takes as it revolves around another object.

Around and Around We Go Every second, that you sit in this classroom, the Earth's orbital motion carries you about 18 miles through space.

Quiz Time!!!!! Make sure ALL your foldables are filled out before you take the quiz!!! Get out a sheet of BLANK notebook paper. Write your name and your partner’s name on the paper. Number your paper from 1-8. Answer each question. Your answer will either be Rotation or Revolution. Turn in this paper by the end of class, for a grade!!!
