Aims

  • Describe the major structural elements of Earth and the major internal forces which affect them.
  • Classify rocks and minerals according to their characteristics and formation.
  • Explain external processes that that cause topographic and soil changes on the earth’s surface.
  • Describe the oceans of the earth and their role in global processes.
  • Describe the earth’s atmosphere and the forces which create weather.
  • Describe some well known effects of particular atmospheric conditions like the Greenhouse effect.
  • Identify global weather patterns and their relationship to different climates.
  • Describe the way in which the earth’s surface has changed over time.
  • Identify environmental issues which are of current significance.

What You Will Do

  • Research how a mountain/mountain range in or near your region was formed.
  • Explain plate tectonics.
  • Collect and classify rock samples as either sedimentary rock, igneous rock, or metamorphic rock.
  • Describe four ways that weathering breaks down rocks to help form soil.
  • Explain how the speed of a stream affects the shape of the landscape.
  • Name the three main layers of the ocean, describe the characteristics and ocean life in each.
  • Keep a record of atmospheric and weather changes in your environment.
  • Explain the highs and lows associated with air pressure, and how they affect weather.
  • Create a questionnaire to determine understanding of the Greenhouse Effect or the Ozone layer.
  • Explain why your region has its overall climate.
  • Research what life forms (plant and animal) inhabited your region before the formation of humans.
  • Identify the rules and laws used to date fossils.
  • Research an environmental problem in your area, and discuss possible solutions.
