| Question | Answer |
|---|---|
| The universe includes | All matter, All space, and nearly 200 billion galaxies |
| The universe is mostly made of | Empty space |
| A galaxy is best described as | A cluster of stars, dust, gas, and matter |
| Our solar system is located in the | Milky Way galaxy |
| Distances between galaxies are measured using | light years |
| Which type of galaxy has long curved arms | spiral |
| What type of galaxy has no definite shape | Irregular |
| The milky way is classified as which type of galaxy | spiral |
| The most accepted theory explaining the creation of the universe is the | big bang theory |
| What existed one second after the big bang theory | Elementary particles |
| which evidence shows the universe is expanding | red shift of light |
| What makes the largest percentage of the universe | dark energy |
| ordinary matter makes up approximately | 5% |
| Dark matter is best described as | matter that affects gravity but cannot be seen |
| Which type of star produces its own energy through nuclear fusion | star |
| Which type of star is very old, small, hot, dense, and dim | white dwarf |
| which star type is the largest and brightest | supergiant |
| What forms when a star is born from a cloud of gas and dust | Stellar Nebula |
| What happens to an average-sized star after it becomes a red giant | it becomes a planetary nebula then a white dwarf |
| what explosive event occurs when a massive stars dies | supernova |
| What can for after a supernova if the remaining core is very large | blackhole |
| Which object is also called a planetoid | Asteroid |
| Which object produces a coma and tail when near the sun | comet |
| which is the smallest extraterrestrial object | meteoroid |
| A space rock traveling through space is called a | meteoroid |
| when it enter earth's atmosphere and burns up it is called a | meteor |
| if it reaches earth's surface it is called a | meteorite |
| A star appears red, very large, and bright but has a cooler surface temperature. What type of star is it, and how do you know | Red giant because it is big, bright, and has a cooler surface temperature |
| Stars are born from | Stellar Nebulae |
| What process provides energy for stars | Fusion |
| What does an average star become after it runs out of hydrogen | Redgiant |
| The sun formed from | A cloud of gas and dust |
| What was the first object to form in our solar | The sun |
| What force helped form the sun and planets | Gravity |
| Which planet is closest to the sun | Mercury |
| Which is the largest planet in the solar system | Jupiter |
| Which planet is known for its large ring system | Saturn |
| Which planet rotates on its side | Uranus |
| Inner planets are rocky and closer to the sun | True |
| outer planets are mostly made of gas | True |
| Jupiter has a solid surface | False |
| Mars appears red because iron oxide | true |
| Neptune appears blue because of methane in its atmosphere | true |
| Describe the difference between rocky planets and Jovian planets | Rocky planets are small, dense, and made of rock and metal. Jovian planets are large and mostly made of gas |
| Why are the inner planets rocky while the outer planets gaseous | The sun was too hot near the center for gases to stay, so only metals and rocky materials formed close to the sun. Gases were able to collect father away. |
| What happens to a massive star at the end of its life | A massive star becomes a supergiant, explodes in a supernova, and then becomes either a neutron star or a blackhole. |
| Put the stages of star's life in the correct | Stellar nebula, Main sequence star, Red giant/ supergiant, supernova, neutron star or blackhole, white dwarf, and black dwarf |
| Mercury | Smallest planet, has no moons |
| Venus | Thick carbon dioxide atmosphere, no moons |
| Earth | Has life and liquid water |
| Mars | Red planet with iron oxide |
| Jupiter | Largest planet, mostly hydrogen |
| Why is Pluto no longer considered a planet | Not cleared its orbit of other objects and is classified as a dwarf planet |
| What do all inner planets have in common | They are rocky |
| Which of the following is NOT a characteristic of the outer planets | They have short periods of revolution |
| The four outer planets are also known as | Gas giants |
| Which planet is known for rotating on its side | Uranus |
| Larger planets tend to | Have stronger gravity, rotate faster, and made of gas |
| Describe the relationship between a planet's distance from the sun and its temperature | planets closer to the sun have higher average temperatures, while planets farther away are colder because they receive less energy from the sun |
| What is the goldilocks zone and why is earth in it | The goldilocks zone is an area around the sun where temperatures are just right for liquid water to exist. Earth is in the zone, which allows us to survive. |
| How does a planet's distance from the sun affect its period of revolution | The farther the planet is from the sun, the longer its period of revolution because it has a greater distance to travel around the sun. |
| Which planet is most similar to earth in size and composistion | Venus because it has a similar size, mass and composition. |
| Why do the inner planets have much higher densities than the outer planets | They are made of solid rock and metal, and outer planets are made of gas |
| Explain why outer planets have longer periods of revolution than inner planets | Outer planets have longer periods of revolution because they are farther from the sun and must travel a much larger orbit to complete on revolution. |
