Welcome to Astronomy! Find your place in Space!
Astronomy The study of the Moon, Stars, and other objects in space.
Rotation Rotation is a planet spinning on its’ axis. An axis is an imaginary line through the poles Causes night and day One rotation = One day
Revolution Revolution is the movement of one object around another An orbit is the path an object takes as it revolves One revolution = One year
What causes night and day? A. Rotation B. Revolution C. Astronomy
One ___________ = One year A. Rotation B. Revolution C. Astronomy
One Rotation= One __________ A. Day B. Revolution C. Year
Seasons Caused by Earth’s tilt 23.5 degrees
Solstice Occur in June and December When the sun is directly over head at 23.5 degrees North or South Creates the longest and shortest days of the year
Equinox Occur in March and September When the sun is directly on the equator Means equal day and night
What causes seasons? A. Rotation B. Revolution C. Tilt
The longest day of the year is the_________. A. Summer solstice B. Winter solstice C. Fall Equinox D. Spring Equinox
What is the shortest day of the year? A. Summer solstice B. Winter solstice C. Fall Equinox D. Spring Equinox
What comes after the summer solstice and is has equal day and night? A. Summer solstice B. Winter solstice C. Fall Equinox D. Spring Equinox
Review What is rotation? What is revolution? What causes the seasons? What is a Solstice? What is an Equinox?

Why do our seasons change?
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’s Tilt and Rotation
What are they and why are they important to us?
Today’s Agenda… Bellringer: Identify each as rotation or revolution (this is not multiple choice) A. Takes 24 hours B. Spins on Axis C. Takes 365 ¼ days.
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 in Space. All planets REVOLVE around the sun. Revolution is the movement of one object around another. One revolution equals the time it takes to.
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.
4 Seasons: 1.1 Notes imgres. Astronomy study of the stars, moon, planets and other objects in space.
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 in Space Section 1-1 P
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.
The Seasons A Northern Hemisphere Perspective. The Seasons Definitions Axis: An imaginary axle that passes through the North and South Poles Rotation.
Movements of the Earth The Earth’s Motion in Space.
