Why do objects revolve around the sun? the way no one answers Hi! Here are the answers for Unit 2 of Lesson 13 Solar System Unit Test. I promise 100% this is correct. (For Grade 6 Connections Academy)
1. A video shows objects in the solar system orbiting the sun. Why do objects revolve around the sun?
A: The sun is so massive that it has the most gravity.
2. Suppose a person builds a sandcastle of lunar sand on the moon. What would that person find there a month later?
A: The sandcastle would stay in place the same size 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 the same size?
A: asteroids and comets
4. Why is the pressure so high 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 is made up 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 build scale models of natural phenomena?
A: to better observe patterns and relationships
8. Which planet is about four times larger than the diameter of Venus on a model?
A: Neptune
9. How does distance affect gravity?
A: Gravity increases with decreasing distance.
10. What is used by scientists to organize the history of the Earth?
A: geological time scale
For questions 11 to 13, DO NOT COPY AS YOU ARE PLAGIATING. YOU WILL BE IN PROBLEM.
11. A model shows that the moon grew to double its size, but remained in the same place. In one or two sentences, explain how this would impact the gravity between the Earth and the Moon.
A: If the moon grew twice its size, its mass would be enormous, so the gravity between the Earth and the moon would be twice as great. The reason for this is that the greater 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 almost entirely made up of carbon dioxide and methane. In three to five sentences, make a hypothesis about the surface temperature of the planet. Explain your answer using information about the planet’s location and atmosphere.
A: My guess is that the planet’s surface temperature will be scorching hot. Methane and carbon dioxide are greenhouse gases, so they trap heat. The gases would then make the globe hot. Also, if the star’s distance is similar to that of Venus, the sun would heat the world, allowing the gases to pick up the extra heat.
13. A student wants to draw a model of the solar system. In three or four sentences or bullet points, explain the steps 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 the distance between each planet and the sun in 2. AU, then make one AU equal to one cm.
3. Measure the distance of each planet from the sun in cm.
4. Draw the sun with the planets. Idk Ok I’m fine no I’m not what the answer is Thinking the same I’ll put the answers when I’m done ✌🏻 Come on we need therapy I really need the answers ASAP suns graitational pull The fact that I came here to get an answer :-: the fact that NO ONE answers >:[] |_Ribbit_|
