The spinning of the Earth on it's axis
Rotation
The elliptical path the Earth takes to travel around the Sun.
Orbit or revolution
What galaxy to we reside in?
The milky way
Earth and Mars are part of this group of planets.
inner planets or terrestrial planets
Which type of gas is most abundant on the Sun?
hydrogen
The direction that the earth rotates
Counter-clockwise (objects appear to move east to west)
At these times of year (Seasons) the sunlight shines equally on the northern and southern hemispheres.
Spring and Fall
The two things that are provided by our star, the Sun.
heat and light
The barrier that separates the terrestrial planets from the gas giants.
Asteroid belt
One the SUN
The length of time that it takes Earth to rotate.
24 hours about 12 hours of day and 12 hours of night.
In this season the Northern Hemisphere is tilted towards the sun, causing longer daylight hours and more direct sunlight.
Summer
What are the 3 basic types of galaxies?
spiral, elliptical, irregular
What force drives the movement of our solar system?
gravity
This phase reflects sunlight on half of its "face."
1st or 3rd Quarter
What phase of the moon is shown here? 
New Moon
This part of the Earth gets the most direct light from the sun and has the least variation in daylight hours. It is also the region of the world with the most rainforests.
The Equator
A unit of astronomical distance equivalent to the distance that light travels in one year, which is 9.4607 × 1012 km.
light year
Objects made of dust, gas and ice. The closer they move towards the sun, a tail is seen trailing behind.
comets
The outermost layer of the Sun's atmosphere.
Corona
The amount of time is takes the Earth to orbit the Sun.
~365 days
1. Length of day and night
2. Seasons
3. Star patterns
What phenomenon happens as the universe expands causing the wavelength of light emitted from galaxies to stretch?
red-shift
The relationship between a meteoroid, a meteor and a meteorite.
Meteoroid is floating in space, the meteor is traveling through Earth's atmosphere and a meteorite has made it to the surface (land).
Explain why the moon seems to change shape in the night.
The moon appears to change because of the amount of light it reflects as it orbits the Earth. It takes about 28 days to complete a revolution and you will see 8 different phases of the moon.
