1 Name EMS Study Guide Fill in the blank. 1. A is a star and the objects that travel around it. 2. A star is a huge of hydrogen and helium gas that give off its own. 3. Think about our own solar system. It has to have a STAR and OBJECTS that travel around the star. The star in our solar system is Two important objects that travel around our star are: and 4. A planet is any celestial (heavenly) body that is massive enough to be and that orbits the. 5. Planets are different from stars in 3 main ways: Planets are not - they don t give off light like stars do Planets are made of gas and - stars are only made of gas Planets a star stars do not orbit other stars 6. Planets are different from moons because: Planets a star moons do not Moons planets 7. Orbit means to follow a path around another object. Orbits have 2 general shapes: 8. The two largest and most important components (parts) of our solar system are:
2 9. We have 8 planets in our solar system. They are: M V E M J S U N 10. Scientists used to think was also a planet, but now they classify it as a dwarf planet. 11. Pneumonic devices (memory tools) to remember the name of the 8 planets My very enormous martian just sings until noon Mary s violet eyes make John sit up nights 12. Label the 8 planets and the 1 dwarf planet in the picture below.
3 EMS FACT # 1 The sun appears to move across the sky every day, but it really does not move. It seems like the sun is moving because of the rotation of the Earth on its axis. 13. The sun appears to rise in the and set in the 14. An imaginary line running through Earth s North Pole and South Pole. 15. Earth ROTATES on its axis. That means it. 16. Earth rotates from to. That means it spins counterclockwise. 17. Earth makes one rotation every. That is rotations per year! About how many rotations does Earth make each month? 18. Earth is tilted on its The axis is NOT straight up and down! EMS FACT # 2 Earth is constantly rotating slowly on its axis; it is spinning. At the very same time, Earth is moving much more slowly through space following its orbit around the Sun. 19. Earth around the Sun. That means it moves around the Sun in a circular path. 20. an orbit around the Sun. All planets revolve around the Sun. 21. Earth revolves around the Sun in a path. 22. Earth takes one to make a complete revolution around the Sun. EMS FACT # 3 You know Earth orbits the Sun. But did you know the Moon orbits Earth? 23. The Moon orbits the Earth in a path. 24. The Moon takes a to make one revolution around Earth.
4 _ 25. How many times does the moon orbit Earth while the Earth is making one revolution around the Sun? Explain why you think this. Complete each question below. Use the diagram to help you. [1 point each] 26. The diagram shows the position of Earth (E) now. Where will Earth be in six months? A. near position 1 B. near position 2 C. near position 3 D. near position On the diagram above, let s say that on Earth (E) it is March. Which statement below is true for the Northern Hemisphere? A. The North Pole is tilted away from the Sun. B. The North Pole is tilted toward the Sun. C. The length of day and night are equal. D. Earth is experiencing the winter solstice. 28. When the Northern Hemisphere is experiencing autumn, what is true for the Southern Hemisphere? A. It is winter in the Southern Hemisphere. B. It is summer in the Southern Hemisphere. C. It is spring in the Southern Hemisphere. D. It is fall in the Southern Hemisphere.
5 29-31 Use the diagram above to answer the questions below. Assume that it is March on Earth (E) in position Which position represents WINTER for the Northern Hemisphere? 30. Which position represents FALL for the Northern Hemisphere? 31. Which position represents SPRING for the Northern Hemisphere? 32. TRUE or FALSE? The seasons are caused by Earth rotating on its axis. 33. (5 ESS #1) Which explains the pattern of day and night? A. Earth orbits the sun. B. Earth spins on its axis. C. The sun only transmits light energy during the daytime. D. The sun only transmits light energy above the equator. 34. (5 ESS #1) Which diagram shows the flagpole at 5:00 p.m. on a summer day? 35. (5 ESS #3) About how much of Earth s surface is covered by oceans? A. less than 20% B. about 50% C. about 70% D. more than 90% 36. (5 ESS #3) A class was learning about the pattern of day and night on Earth. What part of Earth experiences night at the same time? A. less than C. about B. about D. almost all
6 37. (5 ESS #2) Which number in the diagram represents Earth? A. 1 B. 2 C. 3 D
