Presentation Transcript

  1. An earthquake, mountains can form, a volcanic eruption • What can happen when the plates of the lithosphere crash into each other?

  2. Wind, moving water, plant’s roots, glacial movement • What processes can weather the Earth’s crust?

  3. What do we call the huge pieces of crust? • Plates

  4. Pangaea • What do scientists call the huge landmass which formed about 200 million years ago?

  5. 5,000,000,000 (5 billion) years ago • About how long ago did planet Earth and our solar system form?

  6. The Hydrosphere • What do we call all the water (glaciers, oceans, rivers, water vapor) on Earth?

  7. Magma • What do you call hot, molten rock inside the Earth?

  8. A geologist • What is the name of the scientist that studies the history of the Earth as it is told by rocks?

  9. What are the layers of gases called that surround the Earth? • The atmosphere

  10. What test will a geologist perform to identify a chemicalreaction? • The acid test

  11. Weathering • What process wears rocks and breaks down rock into bits and pieces?

  12. This test is performed to see if a rock sample has any metals Conductivity or Electricity Test

  13. The Outer Core • Which layer of the Earth is made of molten metals…nickel and iron?

  14. Sedimentary Rock • Fossils (the imprint of a plant or animal) can be found in this kind of rock:

  15. The Crust or Lithosphere • Which layer of the Earth is made of solid rock?

  16. Igneous Rock • What kind of rock is formed from cooled magma or lava?

  17. Erosion • What process carries and moves rock material – sediments – to a new location?

  18. The water cycle The earth uses the same water over and over again. Evaporation, condensation and precipitation are part of this process.

  19. The Streak Test • This test will identify a rock’s true color.

  20. Minerals • All rocks are made of …

  21. Condensation • Water vapor rises into the atmosphere, cools, and then changes to a liquid or ice crystals…this process is called ___

  22. Luster • This property is used to describe how a rock reflectsthe light…its shininess. This property is called ___
