24.2 Sun and Seasons

Seasons. What Causes Seasons? Seasons are caused by the tilt of the earth’s axis as it moves around the sun. Seasons happen because the Earth is tilted.

Earth’s Seasons. Rotation 1.The imaginary line that passes through Earth’s center and the North and South poles is called Earth’s axis. 2.Earth spinning.

Days, Years & Seasons. Days and Nights Rotation: the Earth turns around on its axis 1 day=24 hours (one rotation) One half of the Earth is always in light.

Why do we have day and night?. Earth’s rotation  The Earth rotates on its axis (imaginary vertical line around which Earth spins) every 23 hours & 56.

What causes seasons? The tilt of the Earth on its axis The 23.5° tilt is caused by the interaction between the Moon and the Earth.

Seasons on Earth Two reasons the Earth has seasons: 23.5 degree tilt

The Earth and its Motions Science 8 Astronomy Notes Page 6

The Earth and its Motions The Earth rotates or spins on its axis The rotation time is 24 hours or 1 day

The Earth and its Motions The Earth revolves or travels around the sun The revolution time is 365 ¼ days or 1 year Ever wonder what leap year is or why is there are 29 days this month? Click here…

The Earth and its Motions The Earth does not stand straight up on its axis The Earth is tilted at an angle of 23 ½° on its axis. Why is 23 ½° North or South of the Equator significant?

Putting it all together… What causes day and night? The Earth’s rotation and its spherical shape causes half of the Earth to face the sun (day) and half to face away (night). DAY NIGHT

Putting it all together… What causes seasons? The Earth’s revolution and its tilt on its axis causes the sun to hit certain parts of the Earth more directly (summer) and parts less directly (winter).

The Winter Solstice Is the 1st day of winter Minimum hours of daylight Happens around December 21st (in the Northern Hemisphere) Most direct rays hit south of the Equator (at 23 ½° S)

The Summer Solstice Is the 1st day of summer Maximum hours of daylight Happens around June 21st (in the Northern Hemisphere) Most direct rays hit north of the equator (at 23 ½ °N)

The Vernal Equinox Is the 1st day of spring Equal hours of daylight and darkness Happens around March 21st (in the Northern Hemisphere)

The Autumnal Equinox Is the 1st day of autumn (fall) Equal hours of daylight and darkness Happens around September 21st (in the Northern Hemisphere)
