Earth’s Tilt The Earth’s axis is tilted 23 ½ degrees. Tilted Axis 23 ½ Degree Tilt Tilted Axis The Earth’s axis is tilted 23 ½ degrees.

Earth’s Seasons Equator Axis Earth Northern Hemisphere Southern Hemisphere Sun Caused when the different hemispheres of Earth are tilted toward or away from the Sun.

Earth’s Seasons More direct rays of light Less direct rays of light Sun Northern Hemisphere Southern Hemisphere The hemisphere tilted toward the Sun gets more direct light rays from the Sun which makes it hotter in that area.

Earth’s Seasons Less direct rays = winter More direct rays = summer Sun Summer in this hemisphere. Winter in this hemisphere. Northern Hemisphere Southern Hemisphere Less direct rays = winter More direct rays = summer

Earth’s Seasons Northern Hemisphere Southern Hemisphere Sun When both hemispheres get an equal amount of light, we have fall or spring.

Earth’s Seasons Spring – Northern Hemisphere Summer Northern Hemisphere Winter Northern Hemisphere Fall – Northern Hemisphere The reason one hemisphere is tilted more towards the sun is due to the Earth’s revolution around the Sun.

Fall and Spring Northern and Southern Hemispheres are getting an equal amount of Sun’s direct rays. *Sketch and label fall and spring. Sun Fall Spring

Winter Northern Hemisphere is getting less of the Sun’s direct rays. *Sketch and label winter and summer. Northern Hemisphere is getting less of the Sun’s direct rays. Sun Summer Winter

Summer Northern Hemisphere is getting more of the Sun’s direct rays. *Sketch and label winter and summer. Sun Summer Winter
