REVIEW FOR TEST ON THURSDAY!!!! 1. Scientist can use ______________________ for satellites, solar panels, telescopes, and many other instruments, to study space, or make our lives easier. A. gravity B. Solar Wind C. Sunspots D. Electromagnetic Radiation 2. The chart below shows the regions of the Electromagnetic Spectrum arranged by wavelength and frequency. Which region in the electromagnetic spectrum would UV light most likely be found? Region A Region B Region C Region D 6. Two physical properties of a star are apparent magnitude and absolute brightness. Apparent magnitude is the brightness of a star as seen from Earth; it can be determined using the distance the star is from the Earth. Absolute brightness is determined by size and temperature, what other factor is used to determine absolute brightness? A. The light is located in the visible light portion of the EM spectrum. B. The brightness a star would have if it were at a standard distance from Earth. C. The movement of sunspots on the sun. D. Huge loops of gas on the sun called prominences. 7. Which two factors determine the brightness or magnitude of a star? A. Size and Temperature Temperature and Density B. Density and Color C. Color and Mass D. 8. The hottest stars are blue, and the coolest stars are red. Why are stars different colors? A. Region A B. Region B C. Region C D. Region D 3. Different parts of the sun rotate at different speeds. Which piece of information below helped scientist to determine this? A. They can watch the movement of sunspots across the surface of the sun. All the spots do not move at the same rate. B. The Sun orbits or revolves around the Earth. C. Because there are 6 main layers of the Sun. D. The Earth and Sun are both rotating and revolving at the same rate. 4. Areas of the sun’s surface are cooler than the surrounding regions. What are these dark spots called? A. Solar Flares B. Prominences C. Solar Wind D. Sunspots 5. A prominence is a large, bright, gaseous feature extending outward from the Sun's surface. They link sunspots together. What shape do these features take on the surface of the Sun? A. A wind that blows out into space B. A loop C. A dark spot D. A deep hole A. B. C. D. They are different temperatures. The color depends on their size. The planets they are located near. They are closer or further away from the sun. 9. Astronauts weigh less on the Moon than they do on Earth. Which of the following best explains why astronauts weigh less on the Moon than on Earth? A. Earth’s gravity is stronger than the Moon’s. B. Astronauts have less density on the Moon. C. Astronauts have more mass on Earth than on the Moon. D. Earth has more friction than the Moon. 10. Which of the following would change as an object, such as an asteroid, moves closer to a large star? A. The asteroid’s mass B. The asteroid’s density C. The asteroid’s gravity D. The asteroid’s weight 11. The gravitational pull of the sun plays a huge part in the structure of our solar system. Which of the following describes how it impacts our solar system? A The gravitational pull makes our planets the size they are. B. The gravitational pull keeps our planets in their orbits around the sun. C The gravitational pull gives our planets their color. D The gravitational pull keeps comets from coming into our solar system. 12. Which of the following has the biggest impact on the formation of a solar system? A. Magnetism B. Heat C. Friction D. Gravity 13. Which of these would light take the longest time to cross? A. A star B. A nebula C. A moon D. A galaxy 14. There are several statements below. Which statement about the universe is true? A. B. C. D. It contains millions of stars contained in thousands of galaxies. It contains hundreds of galaxies with billions of stars. It contains billions of galaxies and stars. It contains thousands of the galaxies made up of millions of stars. 15. The approximate size of the solar system is listed below; it includes Earth, the Milky Way, the Moon, and the Sun. The A end is the smallest object, the D end is the largest object. Which object would be located at point C? A B A. Earth B. Milky Way C C. Moon 18. What does it mean when we say the star, Proxima Sagittarii, is a little over 9.5 light years from Earth? A. Proxima Sagittarii is 9.5 million miles away from the Earth. B. It takes 9.5 years for light from Proxima Sagittarii to reach the Earth. C. Proxima Sagittarii’s distance from the Earth is 9.5 times the distance from the Earth to the sun. D. It would take 9.5 light years for a person traveling on a rocket to reach Proxima Sagittarii. 19. Which of the following would change as an object, such as an asteroid, moves closer to a large star? A. The mass of the star would increase, so its gravity would change. B. The mass of the asteroid would increase. C. The frictional force on the asteroid would increase, so it would slow down. D. The gravitational pull on the asteroid increases, so it speeds up. 20. The graph below shows some of the data for sunspot activity over a period 400 years. D D. Sun 16 . Which of the following is the greatest distance from Earth? A. The nearest star to Earth. B. The nearest planet to Earth. C. The nearest galaxy to Earth. D. The nearest asteroid to Earth. 1 7. Venus has a very thick atmosphere that makes Venus one of the hottest planets. Scientists make new discoveries about atmospheres, and learn about new things every day! What makes it possible for scientists gather new information about atmospheres we never studied before? A. People like you designing new instruments and technology that help them see things they could never see before. B. New theories that change the way scientists interpret already known data. C. Scientists who develop new spacecraft that can collect data on the planet’s surface. D. Scientists that change laws on a regular basis. Based on the data above, which of the following can be best concluded? A. Sunspots will NOT occur after the year 2,000. B. Sunspots are caused from space objects, like meteoroids, hitting the sun. C. Sunspots occur about every 11 years. D. Sunspot activity will cause the rotation of the sun to increase every year. Explain what will happen to the sunspot number after the year 2,000.
