<p>I dunno if there are many people here who are taking APES (doesn't look like it) but I figure it's worth a shot.</p>
<p>Name 3 renewable energy sources with one pro and one con for each.</p>
<p>bumpppppppp</p>
<p>solar - no pollution, only good when sun is it
wind - abundant, need consistent wind and backup for places that dont get much wind</p>
<p>carbon cycle steps</p>
<p>To add to the, and make the 3rd, renew. energy sources:</p>
<p>Hydroelectric: abundant (except droughts), can cause flooding</p>
<p>Geothermal: no warming gases, but not available everywhere
Tidal: no emissions, but not available to use everywhere and still in early stages of development
hydroelectric: damages habitat</p>
<p>What are the layers of the atmosphere in order?
Soil layers in order?
The six groups of air pollutants?</p>
<p>layers of atomsphere from closest to earth: troposphere, stratosphere, mesosphere, ionosphere</p>
<p>pollutants: ozone</p>
