Factors impacting the environment test review

  1. 1. Factors Impacting the Environment Test Review This PowerPoint can be found on my TeacherWeb page in the 2nd 9 Weeks Notes section.
  2. 2. ecoregion – large unit of land or water containing a geographically distinct assemblage of species, natural communities, and environmental conditions
  3. 3. Lighthouse Rock, Palo Duro Canyon, Texas
  4. 4. Davis Mountains, West Texas
  5. 5. Texas Gulf Coast
  6. 6. Piney Woods of Texas
  7. 7. Edwards Plateau, Texas
  8. 8. weathering – the breakdown of rock into smaller pieces by natural processes  Chemical:  Abrasion: grinding and wearing down of rock  Oxidation: chemical surfaces by other rocks reaction in which an element combines with or sand particles oxygen  Ice wedging: process  Acid rain: rain that where water seeps into absorbs weak acid that cracks in a is in the air because of rock, freezes and pollution expands over an over causing the cracks to get bigger  Mechanical:
  9. 9. erosion – process by which wind and water move sediment from one place to another Agents of erosion and weathering: Ice and glaciers Snow Wind Water Waves Gravity
  10. 10. drought – an extended period of dry weather resulting in a severe shortage of water
  11. 11. tsunamis – a large wave or series of waves that is caused by an earthquake or volcanic eruption
  12. 12. volcanoes – an opening in the earth’s crust in which molten lava, ash, and gases are ejected
  13. 13. hurricanes – a rotating tropical storm whose winds have reached a constant speed of 74 mph or more
  14. 14. deposition – the process by which transported materials are left in new locations
  15. 15. lightning – a massive electrostatic discharge between the electrically charged regions within clouds or between a cloud and the Earth's surface
  16. 16. earthquakes – shaking and vibration at the surface of the earth resulting from underground movement along a fault plane or from volcanic activity
  17. 17. How does a volcanic eruption affect the local environment?  Lava flow can burn down trees and other vegetation in its path, along with manmade structures. If it runs into an ocean, it might damage or kill a coral reef, as well as cause the water to boil, killing the life within.
  18. 18. How does a volcanic eruption affect the local environment?  Ash and dust is thrown into the atmosphere, which blocks the sun’s light. This can lower the temperature of an area for a period of time, as well as prevent plants from getting the sunlight they need for photosynthesis. Weather patterns are altered during this time.
  19. 19. How does a volcanic eruption affect the local environment?  Lava flows are destructive, but over time can add new material to a landscape
  20. 20. Explain why our earth experiences earthquakes .  Our earth’s crust is made up of many pieces like a puzzle covering the surface of the earth. Not only that, but these puzzle pieces keep slowly moving around, sliding past one another and bumping into each other. We call these puzzle pieces tectonic plates, and the edges of the plates are called the plate boundaries. The plate boundaries are made up of many faults, and most of the earthquakes around the world occur on these faults as rocks suddenly shift or break under stress.
  21. 21. Tectonic Plates
  22. 22. Name and describe a large storm that develops over an ocean. List all names for it.  Hurricanes can be up to 600 miles across and have strong winds spiraling inward and upward at speeds of 74 to 200 mph. Each hurricane usually lasts for over a week, moving 10-20 miles per hour over the open ocean. Hurricanes gather heat and energy through contact with warm ocean waters. Evaporation from the seawater increases their power. Hurricanes rotate in a counter-clockwise direction around an "eye" in the Northern Hemisphere.
  23. 23. Hurricanes
  24. 24. Other names for hurricanes  Tropical storms occur in several of the world's oceans, and except for their names, they are essentially the same type of storm. In the Atlantic Ocean, Gulf of Mexico, and the Eastern Pacific Ocean, they are called hurricanes. In the Western Pacific Ocean, they are called typhoons. In the Indian Ocean, the Bay of Bengal, and Australia, these types of storms are called cyclones.
