Can somebody please tell me all 13 questions to this solar system unit test even the one's i have to write on please i need help fast
im doing the solar system unit test too
I NEED HELP PLEASE
Wait i will send it in soon
PLSSSS HELP MEEE
so which ones are right? Like who is right
hey can someone help me pleeeeeeeeeeeeeeeeeeeeeeeeesssssssssss
hay food person can YOU HELP ME PLEASE
Hi! Here are the answers for Unit 2 Lesson 13 Solar System Unit Test. I promise 100% it is correct. (For 6th Grade Connections Academy)
1. A video shows the objects in the solar system orbiting the sun. Why do objects orbit the sun?
A: The sun is so massive that it has the most gravity.
2. Suppose a person built a sandcastle of moon sand on the moon. What would that person find there a month later?
A: The sandcastle would remain in place the same size that it was because the moon has no wind.
3. Use the scenario to answer the question. A student creates a diagram comparing the sizes of objects in the solar system. Which two objects are often similar in size?
A: asteroids and comets
4. Why is the pressure so high deep inside the outer planets?
A: They have very large gas masses.
5. Which planet is most similar in size to Earth?
A: Venus
6. Use the scenario to answer the question. A student makes a chart about galaxies and mentions that the universe consists of many galaxies such as the Andromeda galaxy and the Milky Way galaxy. Which statement is true about these two galaxies?
A: They both exert a strong gravitational pull on each other.
7. Why do students and scientists construct scale models of natural phenomena?
A: to better observe patterns and relationships
8. Which planet is approximately four times larger than the diameter of Venus on a scale model?
A: Neptune
9. How does distance affects gravity?
A: Gravity increases with decreasing distance.
10. What is being used by scientists to organize Earth’s history?
A: geologic time scale
For questions 11 to 13, DO NOT COPY BECAUSE YOU ARE PLAGIARIZING. YOU WILL BE IN TROUBLE.
11. A model shows that the moon has grown to twice its size, yet it has remained in the same place. In one to two sentences, explain how this would impact the gravity between Earth and the moon.
A: If the moon grew twice its size, its mass would be huge, then the gravity between Earth and the moon would be twice as much. The reason is that the larger the mass of an object, the more gravity it has.
12. Use the scenario to answer the question. Scientists have discovered a new planet. The planet is in a solar system whose star is similar in size to the sun and is about as far from the star as Venus is from the sun. The planet is similar in size to Earth, and its atmosphere is similar in thickness to Earth’s atmosphere. The atmosphere is composed almost entirely of carbon dioxide and methane. In three to five sentences, make a hypothesis about the temperature on the planet’s surface. Explain your answer using information about the planet’s location and atmosphere.
A: My hypothesis is that the temperature on the planet's surface will be scorching. Methane and carbon dioxide are greenhouse gasses, so they will trap heat. The gasses would then make the globe hot. Also, if the distance from the star is similar to Venus then the sun would heat the world, which lets the gasses capture extra heat.
13. A student wants to draw a scale model of the solar system. In three to four sentences or bullet points, explain what steps should be taken to create this model.
A: How To Make A Scale Model of the Solar System:
Get pencils, a ruler, and paper.
1. Make a table of how far each planet from the sun is in 2. AU, and then make one AU equals to one cm.
3. Measure the distance of each planet from the sun in cm.
4. Draw the sun with the planets.

Those are the answers. Literally Gogeta.
didnt the school speccificly say not to do this?
They switch up the answers for each student.
11.The moon growing twice it's size would impact the gravity between Earth and the Moon by consuming much of the gravity in space. That's because we've learned that the Earth's moon is already 3,500 km across. That's my answer. :)
Thanks Abro you are correct.
this is for 7th idk why it said 6th but i works for both
