Motions and Their EffectsSeasonal Change and Planetary Movement
Seasons The tilt of the Earth’s axis is 23.5 degrees This tilt causes seasonal changes
Winter Solstice December 21 or 22 North Pole in darkness for 24 hours South Pole has continual daylight Sun is at its lowest point
Why do we have winter? Fewer hours of sunlight during the day North pole is tilted away from the sun Light rays are less direct
Vernal Equinox (equal)March 20 or 21 (Spring) Sun is directly over the equator Every part of the Earth experiences equal hours of day and night
Summer Solstice June 20 or 21 South Pole in Darkness North Pole in Light Sun appears at its highest point
Why we have summer? Daylight hours are longer Sunlight is more direct
Autumnal Equinox (equal)September 22 or 23 (Fall) Equal hours of day and night Sun is directly over the equator
Questions How many months apart are the solstices and the equinoxes? How is the vernal equinox similar to the autumnal equinox?
Questions What are the differences between the summer and the winter solstices? Why do we have changes in seasons during the year?
Kepler Each planet moves in an elliptical orbit (stretched out circle) Planets speed up their orbit as they approach the Sun and slow down as they move away from it
Questions What was Kepler’s contribution to the understanding of planetary movement? TRANSPARENCIES
Do Now In your notebook, answer the following question in complete sentences: What causes the seasons?
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
Season Vocabulary Seasons – A pattern of temperature changes & other weather trends over a year.
Seasons. Seasons happen because of Earth’s tilt on its axis AND revolution around the Sun. Axis- imaginary line drawn from the north to the south pole.
The Tilt of Earth Terms Earth’s tilt 23.5°
Earth moves in 2 ways: Rotation (spinning of the Earth’s axis) and Revolution (Movement of one body in space around another) Earth’s rotation causes.

How does the Earth move in space? What causes the cycle of the seasons on Earth?

Seasons By: Brittany D. Alexander. Rotation Earth spins around an imaginary line called the: Axis of Rotation The Earth’s axis is tilted Spinning counterclockwise.
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.

Astronomy The study of the moon, stars, and other objects in space Study the movements of the sun, and moon as they appear to travel across the sky Will.
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.
Aim: What are some of the results of Earth’s Motions? I. Earth’s Motions A. Rotation (Spinning) 1. Day and Night Why does the sun rise in the east and.

MOTION. ASTRONOMY The study of objects in space, including the moon, stars, and planets. Solar system Composed of the sun and the planets which travel.
Earth orbits the sun on a tilted axis. Different hemispheres face the sun at different times. At any time during the summer or winter, one part of the.

Seasons and the Angle of Solar Radiation Rotation: the time it takes a planet to rotate (spin) once on its axis. For Earth = 1 day.

Earth-Sun Relationship. 00 0 latitude – Equator 0 longitude – Prime Meridian (has no affect on climate)
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.
Concept Map. This affects the angle of the Sun’s rays and the length of the daylight hours.

What keeps us doing what we're doing?? There are two things that keep objects rotating and revolving in the universe...

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.
