Sun-Earth-Moon System
Earth compared to the sun:
Earth is _________ than the Sun
Smaller
Summer = June 21
Winter = December 21
What moon phase is it when the moon is not visible?
New Moon
Model
A tool used to represent ideas to provide and explanation
What is an axis?
An imaginary line that runs through the middle of an object around which that object rotates.
Earth is _______ than the Moon
Bigger
Explain how Earth's tilt and its revolution around the Sun contribute to the changing seasons?
Earth's tilt is 23.5 degrees. Its tilt and revolution around the sun cause Earth to hit different angels.
What is the difference between waxing and waning?
Waxing - increasing light
Waning - decreasing light
Orbit
A curved path of one object around a central object
What hemisphere(s) do we live in?
North Western
What is the difference between Geocentric and Heliocentric?
Geocentric - earth is the center of the solar system
Heliocentric - sun is the center of the solar system
What season is it when the south pole is titled towards the sun?
Winter
What moon phase is it when the three-quarters of the moon is visible from Earth. The left side is lite.
Waning Gibbous
What is the difference between revolution or rotation?
Rotation - the movement of one object as it turns or spins around a central point, or axis
What moon phase comes after a full moon?
Waning Gibbous
How does Earth's rotation on its axis contribute to the cycle of day and night? How long does it take?
Earth spins like a top, turning on its axis. When your side of Earth faces the Sun, it's daytime. When it turns away, it's nighttime.
It takes about 24 hours for Earth to make one full spin, creating the cycle of day and night
When Fall occurs on the South of the equator, what season is it?
Spring
The Moon appears to change shape in the sky because of its orbit around Earth. What causes the different phases of the Moon?
The Moon moves around Earth, and we see different amounts of its lit side.
Total Solar Eclipse
When the entire Sun is blocked by the moon
What names do we classify galaxies by?
How does the Moon's orbit compare to that of Earth? What is the significance of the moon always showing the same side?
The Moon takes the same time to spin once as it does to orbit Earth (about 27.3 days), so the same side always faces us
Earth's seasons happen because it is tilted on its axis as it orbits the Sun. What would happen if Earth was not tilted at all?
There would be no seasons, and every place would have the same weather all year.
What moon phase is it when half of the lighted side is visible from Earth and shaped like a semicircle. Light is on the right side?
First Quarter
Lunar Eclipse
When the Moon is covered by the Earh's umbra
What event marked the beginning of the space age and what is its significance?
The launch of Sputnik I. It was significant because it was the first artificial satellite to orbit Earh.
