1 7 th Grade Science Unit: Earth, Sun, and Moon Lesson: ESM 14_ Tides Review Name: Date: Friday, November 4, 2016 Homeroom: OBJECTIVES: By the end of today s lesson, you will be able to SWBAT demonstrate mastery of all tides aims DO NOW 1. Neap Tide 2. High Tide 3. Gravity 4. Spring Tide 5. Low Tide 6. Tidal Range A. When water in the ocean is at its highest point. B. The type of tide that occurs when the Sun, Earth, and moon form a right angle. These tides are not very strong. C. the force of attraction between all masses in the universe. The larger the mass of an object, the more gravitational pull it will have. This is why all of the planets orbit the Sun. D. The difference between the highest level and lowest level of the ocean. E. When water in the ocean is at its lowest point. F. The strongest type of tides which occurs when the Sun, Earth, and Moon are in a straight line.

4 WE DO: Short Answer 1. What is the strongest tide called? Describe the position of the sun, the moon, and the Earth and how it causes the strongest tides. (2 points) 2. In your ANSWER DOCUMENT, what is a neap tide? Draw a diagram of the position of the sun, moon and earth. (2 points) Neap Tide Diagram: 4

5 Term Picture Definition 5

6 Match the term in the box to the correct definition. 1. A tide that occurs when the Sun, Earth, and Moon are positioned to form a right triangle 2. A tide that occurs in an area where the Moon is in a direct line with the location 3. A tide that occurs when the Sun, Earth, and Moon are aligned in a straight line 4. A tide that occurs in an area located at 90 from the direct line of the Moon Word Bank A. High Tide B. Low Tide C. Spring Tide D. Neap Tide 8.7C: Ocean Tides Earth and Space 5. At which points in the diagram would the lowest tides be expected? a. W & Y b. W & X c. Y & Z d. Z & X 2 A diagram of the Moon and Earth system is provided. At which points in the diagram would the lowest tides be 6. Why does the Moon have a greater effect expected? on ocean tides than the Sun? a. The Moon has a greater gravitational pull on Earth s oceans because it is much closer. A W & Y b. The Sun is composed of gases which B have W & X no gravitational pull on Earth s oceans. C Y & Z c. The Moon is composed of a magnetic material which pulls on Earth s oceans. D Z & X d. The Sun is much too far away from Earth to have any gravitational effects. 7. The cyclic rise and fall of ocean tides on Earth is primarily caused by Earth's rotation and the a. temperature differences in ocean currents b. revolution of Earth around the Sun c. direction of Earth's planetary winds d. gravitational attraction of the Moon and the sun 2 6

7 Use the diagram below to answer questions 1-4. All answers MUST be in complete sentences. 1. At which locations could the moon be at to cause a high tide at location X? 2. At which locations could the moon be at to cause a low tide at location X? 3. At which locations could the moon be at to create a neap tide? 4. At which locations could the moon be at to create a spring tide? 5. Which occurs when the moon, the sun, and Earth are in a straight line? a. First quarter moon b. Third quarter moon c. Neap tide d. Spring tide 7

8 6. What two types of tides can be found at location X in the diagram above? 7. How are the Earth, sun, and moon arranged during a neap tide? a. They are in a straight line, and the moon is full or new. b. They are in a straight line, and it is a first quarter or third quarter moon. c. They form a right angle, and the moon is full or new. d. They form a right angle, and it is a first quarter or third quarter moon. 8. List the tide experienced, and moon phase seen, when the moon is at each of the following locations: a. c. b. d. 8
