PLEASE HELP MEEEE
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.
Anyone?!?!?!
the pressure is due to gravity, coupled with their large masses
these planets are called the "gas giants"
To determine why the pressure is high deep inside the outer planets, let's analyze each answer choice:
A. They have very large solid masses.
Having large solid masses does contribute to the overall pressure, but it does not explain why the pressure is specifically high deep inside the outer planets.
B. They are very far from the sun.
While the distance from the sun affects factors like temperature, it does not directly impact the pressure inside the planets.
C. They have rings.
The presence of rings does not directly relate to the high pressure inside the outer planets.
D. They have very large gas masses.
The outer planets, such as Jupiter and Saturn, are composed mostly of gases like hydrogen and helium. These gases have a significant mass and are compressed by the intense gravitational forces within the planets. As you go deeper into the planets, the mass of the gases above exerts pressure on the layers below, leading to high pressure at deep levels.
Therefore, the correct answer is D. The high pressure inside the outer planets is due to their large gas masses.
