The SeasonsWhy equator hot and poles cold?

Weather: due to the uneven heating of the earth’s surface

Direct rays

Indirect rays

Indirect rays

Page 3: AIM: Explain the cause and main characteristics of the seasons globally? OBJ: Given notes and activity sheet SWBAT explain the cause and main characteristics.

The SeasonsSeasons: winter, spring, summer, fall (autumn);

changes in precipitation and temperature during the year.

Cause of the Seasons: tilt of the earth’s axis

Earth’s Tilt: 23.5° from vertical

0° tilt: spring, fall only

23.5° tilt: moderate temperatures

winter (cold), spring, summer (warm), fall

35°- 45° tilt: extreme temperatures

winter (v. cold), spring, summer (v. hot), fall

IMPORTANT:

north pole axis facing Sun: Summer

north pole axis facing away from Sun: Winter

Seasons NOT caused by change in Earth’s distance from the Sun

Earth farthest from Sun: summer (Northern Hemisphere)

Earth closest to Sun: winter (Northern Hemisphere)

N.P. axis faces towards Sun

More hours daylight

40°N-45°N: 15 hrs light
