| 7784775754 | Temperate Rainforest | -Cool Winters, Warm Summers (Seasonal Variation) -Large amount of precipitation (Less rain in winters) -Coniferous Trees -Provide lumber and paper -Northern Hemisphere -East coast of North America and Canada -Fertile soils that are susceptible to land slides and erosion if forests are cleared |  | 2 |
| 7784775755 | Tropical Rainforest | -Warm all year round -Very high amount of precipitation (300-500 mm per month) -Southern Hemisphere -Central America, Africa, South America, Southeast Asia -Great Biodiversity -Poor, thin soils |  | 3 |
| 7784775756 | Tropical Dry Forest/Tropical Deciduous Forest | -Warm all year round -Extreme wet and dry seasons -Wet summer (October to April) and dry winter (May, June, July, August, September) -Southern Hemisphere -India, Africa, South America, northern Australia -Erosion-prone soils |  | 4 |
| 7784775757 | Savanna (Tropical Grasslands) | -Slight seasonal variation (warmer in summer) -Extreme wet and dry seasons -Wet Summer (not as wet as tropical dry forest) -Southern Hemisphere -Isolated Trees -Africa, South America, India, Australia -Zebras, Giraffes, Gazelles |  | 5 |
| 7784775758 | Desert | -Driest Biome -Barely an rainfall -Slight seasonal variation -Saline soils -Little Vegetation -Temperatures drop at night -Northern Hemisphere -Africa, Mexico, Middle East, Asia |  | 6 |
| 7784775759 | Tundra | -Coldest Biome -Warmer in summers, but still cold (5 degrees celsius) -Freezing in winters (-20 degrees celsius) -Northern Hemisphere -Dry -Slightly wet summers -Soil is permanently frozen (permafrost) -Also occurs as alpine tundra at the tops of mountains -Northern Europe, Northern Canada, Northern Asia, Greenland |  | 7 |
| 7784775760 | Boreal Forest/Taiga/Coniferous Forest | -Largest Biome -Northern Hemisphere -Coniferous Trees (Pinecones) -Cold. Cooler in summers (never above 20 degrees Celsius) -Moderate Precipitation -More wet in summer than winter -Poor soils -Moose, Wolves, Lynx, Bears -Northern Europe, Canada, Northern Asia |  | 8 |
| 7784775761 | Chaparral | -Densely thicketed -Highly seasonal -Cool, wet winters and warm, dry summers -Induced by oceanic influences -Northern Hemisphere -California, Chile, Australia -Frequent fires |  | 9 |
| 7850275018 | Rain shadow effect | An area having relatively little precipitation due to the effect of a topographic barrier, especially a mountain range, that causes the prevailing winds to lose their moisture on the windward side, causing the leeward side to be dry. |  | 10 |
| 7850282567 | Climate | the weather conditions prevailing in an area in general or over a long period | 11 | |
| 7850287308 | Weather | The daily conditions of the atmosphere in terms of temperature, atmospheric pressure, wind, and moisture. | 12 | |
| 7850297378 | biome | large land regions with certain types of climate and dominant plant life |  | 13 |
| 7850309634 | Equator | Greater biodiversity occurs in this region of the world | 14 | |
| 7850329090 | Theodore Roosevelt | Established the first national park in 1872 | 15 | |
| 7850337317 | Yellowstone National Park | First national park established by Theodore Roosevelt | 16 | |
| 7850340955 | John Muir | Influential in establishing national parks such as Yosemite and Sequoia National Park | 17 | |
| 7856826407 | El Nino | Warming of the Equatorial Pacific Ocean First, the trade winds near South America weaken. This weakening reduces the amount of water being "pushed west" allowing warm equatorial water from the western Pacific to move eastward toward the west coast of South America. The lack of winds and the movement of warm water and air toward South America suppresses upwelling off the coast of Peru and decreases productivity there, reducing fish populations near the coast. |  | 18 |
| 7856827581 | La Nina | Cooling of the Equatorial Pacific Ocean First, the trade winds near South America increase. This strengthening increases the amount of water being "pushed west" The increase in winds and the movement of warm water and air toward Asia increases upwelling off the coast of Peru and increases productivity there, increasing fish populations near the coast. | 19 | |
| 7856830913 | Upwelling | as the surface currents separate from one another, deeper waters rise and replace the water that has moved away. This upward movement of water brings nutrients from the ocean bottom that supports the large populations of producers, which in turn support large populations of fish. |  | 20 |
| 7856832474 | Effects of El Nino | Eastern Pacific (South America): Increased rainfall (erosion, mudslides) and heat Increased infectious disease Decrease in fish stock due to upwelling cutoff Western Pacific (Asia/Australia): Drought (fires, loss of crops) Can also increase number of Atlantic hurricanes | 21 | |
| 7856833209 | Effects of La Nina | Eastern Pacific (South America): Drought (fires, loss of crops) Western Pacific (Asia/Australia): Increased rainfall (erosion, mudslides) and heat Increased infectious disease Decrease in fish stock due to upwelling cutoff Can also decrease number of Atlantic hurricanes | 22 |
