In which galaxy is our solar system located?
Milky Way
100
What color are the brightest and coolest stars?
The brightest are blue. The coolest are red.
100
What effects does the Earth's orbit and tilt have on Earth?
It can cause the change in seasons.
100
What are the beneficial effects of solar activity on Earth?
Photosynthesis, Vitamin D, and kills heat-sensitive germs.
100
True of False? Comets are larger than asteroids.
False. Asteroids are larger than comets.
200
What units do scientists use to measure distances in space? List units in order from smallest to largest distances.
Astronomical Unit, Parsec, Light Year
200
How are stars classified?
Color, temperature, size, and brightness
200
How many degrees is Earth's axis tilted?
23.5 degrees
200
Name the diagram used to compare stars.
Hertzsprung-Russel
200
Where are most asteroids found in our solar system?
The Asteroid Belt.
300
Describe the Big Bang Theory.
The Big Bang Theory states that the universe was created when a large amount of matter of high temperature and density experienced a violent explosion.
300
Name the layers of the Sun.
(From inside out) Core, Radiative Zone, Convection Zone, Photosphere, Chromosphere, Photosphere, and Corona.
300
True or False? The sun and the moon control the timing and strength of tides.
True
300
Define solar flares.
Solar flares are explosions of energy and magnetic force that develop near sunspots, which are similar to storms.
300
Which has a higher elliptical orbit- Asteroids or Comets?
Comets
400
Describe the Nebular Theory.
The Nebular Theory states that the universe was created as a large rotating nebula cooled, throwing off rings of matter that formed the planets and their moons. The larger mass formed the sun.
400
Name the different types of stars.
Dwarfs, Main Sequence, Giants, and Super Giants
400
True or False? A change in Earth's tilt can cause climate change.
True
400
What are the hazards of excessive solar activity on Earth?
Satellite damage, power outages, radio wave disruption, and skin damage.
400
Compare the composition of comets and asteroids.
Comets are small masses made up of ice and rock, which is usually followed by tail. Asteroids are large masses made up of rock and metals.
500
Which arm of the Milky Way Galaxy is our solar system located?
The Orion Spur
500
Contrast the life cycles of small and large stars. Give examples of both.
A small star, such as a dwarf, can have a longer life cycle, since it has less mass. Larger stars, such as Giants and Super Giants have shorter life spans, because they burn their energy more quickly.
500
Describe the formation and effects of spring and neap tides.
Spring tides are formed as a result of the sun and moon working together to enforce a stronger gravitational pull, producing more extreme high and low tides. Neap tides are formed as a result of opposing forces between the sun and the moon, producing smaller high and low tides.
500
Explain how electromagnetic radiation is connected to stars, such as the sun.
Electromagnetic radiation from a star can produce heat in the form of ultraviolet rays, and it can produce light, such as those within the visible light spectrum.

What is the likelihood of an asteroid striking the Earth's surface?
Unlikely, but the collision depends on the size. Since most matter from space is burned up as it enters the atmosphere, only the largest of objects would strike Earth (larger than 1 kilometer).
