Presentation Transcript

  1. Complete warm-ups 1-5 (on the stool) • Get out Notes 130 120 60 70 30 50 40 10 140 8 7 6 5 4 9 3 2 0 180 80 20 160 90 150 170 100 110 1 Seconds You have this much time remaining:

  2. Section 2 Energy Transfer in the Atmosphere

  3. Section Goals I will describe what happens to the energy Earth receives from the sun. I will compare and contrast conduction, convection, and radiation. I will explain the water cycle.

  4. Vocab Words (Chapter 1 due Friday) Radiation Conduction Convection Hydrosphere Condensation

  5. Some energy from the Sun is reflected back into space some is absorbed by the atmosphere, and some is absorbed by land and water on Earth's surface

  6. Heat—energy that flows from an object with a higher temperature to one with a lower temperature Radiation—energy transferred in rays or waves (Sun) Conduction—transfer of energy when molecules bump into each other through contact (Touching a hot plate) Convection—transfer of heat by the flow of a material (lava lamp)

  7. Clicker Time!!!!! Time for some questions Get your clicker ready… (after slide 7)

  15. 10 0 of 30 transfer through space • Conduction • Convection • Radiation

  16. 10 0 of 30 sun rays reaching earth • Conduction • Convection • Radiation

  17. 30 10 0 occurs with fluids • Conduction • Convection • Radiation

  18. 10 0 of 30 Which Type • Conduction • Convection • Radiation

  19. 10 0 of 30 Which Type • Conduction • Convection • Radiation

  20. 10 0 of 30 Which Type • Conduction • Convection • Radiation

  21. The water cycle—water moves back and forth between Earth's atmosphere and surface http://www.crickweb.co.uk/assets/resources/flash.php?&file=watercycle

  22. Energy from the Sun causes water to evaporate from the hydrosphere, and rise as vapor.

  23. Water vapor in the atmosphere can cool and return to liquid form through condensation. a. When water vapor condenses, clouds of tiny water droplets may form. b. Water droplets collide to form larger precipitation

  24. Condensation

  25. Precipitation
