Compare & Contrast
Explain the difference between 'compare' and 'contrast'
Compare is finding the similarities between 2 or more things
Contrast is finding the differences between 2 or more things
Why does Jupiter take 11 ½ Earth years to revolve around the sun but Earth only takes 365 days?
Because Jupiter is farther away from the sun so it has a longest distance to travel.
Name the planets in our solar system in order from distance away from the Sun starting with the closest.
Mercury, Venus, Earth, Mars, Jupitar, Saturn, Uranus, Neptune
What causes day and night on Earth?
The rotating, or spinning, of Earth on its axis
a natural satellite
moon
What is the main difference between a true planet and a dwarf planet?
Dwarf planets don't have enough gravity (are too small) to push object out of their orbit path.
Fill in the blank: All OUTER planets in our solar system have _________ moons.
Many or more than 14
What should you do the moment you come into Science class?
Get your science notebook and follow the instructions on the board.
Why do we see different phases of the moon at night?
The lit portion of the moon that we can see changes as the moon orbits Earth AND as Earth orbits the sun.
a large cloud of gas and dust
nebula
Order these things from BIGGEST to SMALLEST: planet, solar system, universe, sun, galaxy
Universe, Galaxy, solar system, sun, planet
The farther a planet is from the sun, the longer it's __________ is.
Year
What is the force that causes the gas and dust in a nebula to form into planets and stars?
gravity
What causes years on Earth?
The revolution, or orbit, of Earth around the Sun.
a large gaseous body of burning hydrogen at the center of a solar system
star
What is the main difference between an asteroid and a comet?
Comets are made up of mostly ice OR comets have an irregular orbit.
The slower a planet rotates, the longer its __________ is.
day
What two factors determine how MUCH gravity an object exerts on another object.
Mass and distance
What causes seasons on Earth?
Earth's tilted on it's axis as it orbits the sun.
The unit of measurement we use within our solar system
Astronomical Unit
Why are dwarf planets, planets, and stars round but asteroids and comets aren’t?
Asteroids and comets are large enough to have enough gravity to make them round.
Mercury is closer to the sun than Venus, so why is Venus hotter than Mercury?
Venus has an atmosphere that traps in the heat.
Why won't OUR sun go supernova when it "dies"?
Because it is too small.
What causes the ocean tides on Earth?
The moon's gravity "pulling" on Earth as it orbits Earth
The study of the universe, its history, and everything in it.
