Earth is Always Moving

• Rotates: It Spins on an Axis (an imaginary tilted line that starts at the north pole, goes through Earth's center, ends at the south pole)

• Revolves: It Orbits Around the Sun (takes a circular path around center of the solar system)

Day and Night

• As Earth rotates, different parts of it face the sun.

• Side facing sun - Daytime

• Side facing away from sun - Nighttime

Earth's Revolution

• Means: Orbits (circular motion) around an object (sun)

• Takes: 365 1/4 Days, 1 Year

• Causes: Seasons - Winter, Spring, Summer, Fall/Autumn

Q.

Earth's orbit (circular motion) around an object (the sun) is called its

rotation

revolution

Q.

The revolution of Earth around the sun causes

day and night

seasons

• Slide 16

Seasons

• Tilted Axis + Orbit Around Sun = Seasons

• Tilt of axis never changes, always points in the same direction

• Areas tilted toward the sun get more sunlight and heat (summer)

• Areas tilted away from the sun get less sunlight and heat (winter)

• Question 17
