2. Quick Review Each of the following situations illustrates one of Newton’s Laws using the space shuttle. List which one. 1. The rocket’s engines exert a downward force on the ground but the rocket moves upward. Newton’s ThirdLaw 2. One of the solid rocket boosters on the shuttle produces 1.25 x 107 N of force which accelerates its 5.71 x 105 kg mass to a velocity of 21. Newton’s SecondLaw

3. Quick Review 3. During liftoff, it reaches a speed of 17,180 . It continues at this speed while in orbit because no outside forces are acting on it. Newton’s FirstLaw 4. During liftoff, the shuttle’s engines produce 5.255 x 106 N of force. If the 1.1 X 105 kg at liftoff, estimate its acceleration: 5 x 101.

4. Earth and Space Lesson 6.2 – The Lithosphere

5. I can describe the physical nature of the lithosphere including the density, composition, and location of continental and oceanic crust. (4a) • The Earth’s crust is also referred to as the lithosphere. • The lithosphere is very rigid. It will not bendbut will instead crack.

6. I can describe the physical nature of the lithosphere including the density, composition, and location of continental and oceanic crust. (4a) 3. The lithosphere is less densethan the asthenosphere. A. You can remember this because less dense substances will floaton top of denser substances. Since the lithosphere is on top of the asthenosphere it must be lessdense.

7. I can describe the physical nature of the lithosphere including the density, composition, and location of continental and oceanic crust. (4a) 4. There are two types of lithosphere: a. Oceaniclithosphere is found underneath the oceans. b. Continentallithosphere makes up the continentsof Earth.

8. I can describe the physical nature of the lithosphere including the density, composition, and location of continental and oceanic crust. (4a) 5. Oceanic lithosphere is moredensethan continental lithosphere because of the types of minerals that make up the rock.

9. I can describe the physical nature of the lithosphere including the density, composition, and location of continental and oceanic crust. (4a) 6. The thickest part of the lithosphere is found in mountainranges. a. The tallest mountain on Earth is Mt. Everest. This is also the location on Earth where the lithosphere is the thickest.

10. Guided Practice WORK WITH US…NOT AHEAD OF US!

11. I can describe the physical nature of the lithosphere including the density, composition, and location of continental and oceanic crust. (4a) 1. Which part of the lithosphere is the thinnest? Oceanic lithosphere 2. Which of these describes the lithosphere? • Topmost solid part of Earth in which crust is located • Middle liquid, flowing layer of Earth on which crust floats • Middle plastic, flowing layer of Earth on which the asthenosphere floats • Topmost semisolid part of Earth in which magma chambers for volcanoes form

13. Exit Ticket (5 questions)

14. 1. What is the outermost layer of the Earth called? • Mantle • Asthenosphere • Lithosphere • Inner Core

15. 2. Which layer, the lithosphere or asthenosphere, is more dense? • Lithosphere • Asthenosphere • They have the same density • Sometimes the lithosphere is more dense while other times the asthenosphere is more dense.

16. 3. What type of lithosphere would be found at the Himalaya Mountains, the Great Plains of the U.S. and the Savannahs of Kenya? • Oceanic Lithosphere • Continental Lithosphere • Mountainous Lithosphere • Both oceanic and continental lithosphere

17. 4. Which type of lithosphere, oceanic or continental, is less dense? • Oceanic • Continental • They have the same density • Sometimes oceanic is less dense and other times continental is less dense.

18. 5. Which of the following correctly compares the lithosphere and the asthenosphere? • Both are hot, liquid inner layers of earth. • Both are solid, cool layers of earth close to the surface. • The lithosphere is rigid and less dense than the hot and liquid asthenosphere. • The asthenosphere is rigid and less dense than the hot and liquid lithosphere.
