Discuss with your neighbor

• What is today’s temperature?• Is temperature considered climate or weather?

Why?• There are regions in Texas that rarely receive

any rainfall. Is this statement relevant to climate or weather? Why?

• Does the temperature in our city remain constant throughout the year? Why? Why not?

Weather vs. Climate

Check For Understanding

• What causes the seasons?• What are hemispheres?• When the northern hemisphere is tilted towards

the sun what season is it in the southern hemisphere?

• When it is fall in the northern hemisphere what season is it in the southern hemisphere?

• Why are the hemispheres warmer when tilted towards the sun?

Earth’s Tilt• Tilt: the angle of incline of

the Earth’s axis affects the temperature of a place.

• Revolution: the Earth’s trip around the sun (one year)

• Rotation: the Earth completely rotates on its axis every 24 hours. (alternating between night and day)

Earth’s Tilt• Equinox: when the Sun’s rays fall directly

on the equator, day and night time hours are almost equal (Spring and Fall)

• Solstice: One of two days (June 21 and December 22) on which the Sun’s rays strike directly on the Tropic of Cancer or the Tropic of Capricorn, marking the beginning of summer and winter.

• Direct rays: When a hemisphere is tilted toward the sun, the direct rays of the sun or angle of incidence is higher and it is summer in that hemisphere.

• Indirect rays: When a hemisphere is tilted away from the sun, the direct rays of the sun or angle of incidence is lower and it is winter in that hemisphere.
