  • 1

    something such as oil, coal, or the sun, which can be used to provide power for light, heat, machines, etc: A source from which useful energy can be extracted or recovered either directly or by means of a conversion or transformation process (e.g. solid fuels, liquid fuels, solar energy, biomass, etc.)

    Energy Source

  • 2

    - Extracted from the Earth in gas, liquid, or solid form. - Sources that will at some point run out finite. - Took hundreds of millions of years to form, and once consumed it will take hundreds of millions of years to be replaced or replenished.

    Non-Renewable Energy

  • 3

     Takes millions of years to produce.  Formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years

  • 7

    - Produced from sources that do not deplete or can be replenished within a human’s lifetime. - Sustainable - Most are also clear – They do not require combustion which releases pollutants and greenhouse gases

    Renewable Energy

  • 8

    -Comes from harvesting plant or animal material. - Even though these sources areu sed up during processing, they are classified as renewable because photosynthesis cycles the CO2 back into new crops.

    Biomass

  • 9

    - Heat that comes from deep within the earth’s surface. - Carried to the surface of the earth by water or steam and can be used as clean energy if located close to regions that are strongly affected by movement of Earth’s tectonic plate

    Geothermal Energy

  • 10

    - Also called wind power. - Refers to the process of creating electricity using the wind, or air flows that occur naturally in the earth’s atmosphere. - Modern wind turbines are used to capture kinetic energy from the wind and generate electricity.

    Wind Energy

  • 11

    - Energy harvested from flowing water. - It is one of the first sources used for electricity generation.

    Hydropower Energy

  • 12

    - Sun is the ultimate source for all energy sources and has been producing energy for billions of years. - Does not produce pollution or greenhouse gases.

    Solar Energy

  • 13

    - All matter cycles... it is neither created nor destroyed... - As the Earth is essentially a closed system with respect to matter, we can say that all matter on Earth cycles - _________ the movement (or cycling) of matter through a system – by matter we mean: elements (carbon, nitrogen, oxygen) or molecules (water) - Are the pathways by which essential elements move through the living and nonliving components of Earth's ecosystems. - They are essential for life, providing the nutrients that plants and animals need to survive and reproduce.

    Biogeochemical Cycles

  • 14

    required in relatively large amounts

    macronutrients

  • 15

    required in very small amounts (but still necessary)

  • 18

    The ________ is a special case, as it involves the movement of water between all of the Earth's spheres (atmosphere, hydrosphere, geosphere, and biosphere).

    Water Cycle

  • 19

    Water at the surface (oceans, lakes, rivers, and soils) turns into water vapors; water moves from hydrosphere to atmosphere

    Evaporation

  • 20

    Liquid water is turned into water vapor by the plants; water is moved out of leaves through stomata as water vapor
