What unit of measure is used to measure the distance of objects outside our solar system?
Light Year - the distance light can travel in one year or 9,500,000,000,000 km

Approximately how many days does it take for the Moon to orbit the Sun?
27 to 29 days

Name the three types of heat transfer processes, how each process works, and an example of each
Conduction - the transfer of heat directly from the source to the medium; (stove burner heating up a pan) Convection - the transfer of heated molecules upward forcing the cold molecules downward (example: boiling water, water cycle) Radiation - radiation (heat rays) carried through electromagnetic waves that travels directly from the source of heat - it does not travel through any medium (example: Sun giving you a "sun burn")

What are the Four Seasons found on Earth in science terms?
Winter Solstice (Winter), Vernal Equinox (Spring), Summer Solstice (Summer), and Autumnal Equinox (Autumn/Fall) http://www.enchantedlearning.com/egifs/Earthseasons.GIF

What is an asteroid and where can we find them in our solar system?
An Asteroid is a rocky object, smaller than a planet, sometimes can be called a planetoid or a minor planet. Most asteroids are found in the asteroid belt between Mars and Jupiter.

What galaxy is our solar system located?
Milky Way Galaxy

Define the words: Orbit Rotate Give one example for each word
Orbit is a regular, repeating path that one object in space takes around another one. (example: Earth orbits the Sun) Rotate is to turn around in a circle; to spin (example: It takes 24 hours for the Earth to rotate-spin on its axis)

Winter Solstice

What is a comet? Where can they be found? Draw a diagram and label it.
A Comet is a small object made up of ice, dust and gas that orbits the sun. Jets of gas and dust form long tails that can be seen from Earth. http://spaceplace.nasa.gov/comet-nucleus/en/ http://www.astronomynotes.com/solarsys/comet.gif

People have historically grouped stars into ______________.
constellations

What is a New Moon? What does a New Moon look like from Earth?
A New Moon is the first phase of the Moon Phases where people on Earth can only see the dark half of the moon. http://www.moonconnection.com/moon_phases.phtml

Liquid and gases

Name 3 contrasting characteristics of Summer Solstice vs Winter Solstice
Summer: Longer daylight hours, Warmer temperatures, Earth is farther from the Sun, Earth's axis is tilted toward the Sun, Season contains the longest daylight day of the year Winter: Shortest daylight hours, Colder temperatures, Earth is closer to the Sun, Earth's axis is tilted away from the Sun, Season contains the shortest daylight day of the year

What is a Meteor, a Meteorite, and a Meteroid?
METEOROIDS are small chunks of rock and debris in space METEORS -- or shooting stars -- when they fall through a planet's atmosphere METEORITES are pieces of meteors that survive the journey through the atmosphere and hit the ground.

STARS What is the closest star to Earth? What is the closest star to outside our Solar System? What is the star Earth's axis points to?
What is the closest star to Earth? The Sun (1 AU away) What is the closest star to our Solar System? Proxima Centari (4.2 LY away) What is the star that Earth's axis points to? Polaris (430 LY away)

What is a Full Moon? What does a Full Moon look like from Earth
At a full moon, the earth, moon, and sun are in approximate alignment, just as the new moon, but the moon is on the opposite side of the earth, so the entire sunlit part of the moon is facing us. The shadowed portion is entirely hidden from view.

What is the major force that keeps objects in motion in our solar system, in the universe, and in our galaxy?
Gravity - force that pulls an object toward another Gravity is what makes pieces of matter clump together into planets, moons, and stars. Gravity is what makes the planets orbit the stars--like Earth orbits our star, the Sun. Gravity is what makes the stars clump together in huge, swirling galaxies.

Why do the stars in the sky change location during the night? Why do the stars in the sky change location during he year?
The motion of the stars we see over one night is due to the Earth spinning. The motion of the stars you see over months or a year is due to the Earth orbiting the Sun.
