How long is one rotation of Earth? Earth's Motions How long is one rotation of Earth? One day How long is one revolution of Earth? One year

Rising and Setting of the Sun Rising and Setting of the Moon Rotation Movement of Stars through the sky The Seasons Changing Constellations Revolution

Earth's rate of rotation? How do you calculate Earth's rate of rotation? Watch the sky appear to move One rotation = 360° Time for one rotation = 24 hours 360° ÷ 24 = 15°/hr

How many degrees did the stars move from diagram 1 to diagram 2? 30° (2 hours x 15°)

It is the only one that has not moved!! How can you find Polaris? It is the only one that has not moved!! Follow the “gravy” out of the big dipper to find it!!

Because Polaris can only been seen in the North Northern Because Polaris can only been seen in the North What hemisphere must you be in? Why?

What direction must you be looking? North

What direction do the stars appear to move?

What causes the stars appear to move?
