| 8456707382 | Weather | An area's temperature, precipitation, humidity, wind speed, cloud cover, and other physical conditions of the lower atmosphere over hours or days | 0 | |
| 8456707383 | Climate | A region's general pattern of atmospheric or weather conditions over a long time - years, decades, and centuries | 1 | |
| 8456707384 | Latitude | Distance from the equator | 2 | |
| 8456707385 | Elevation | Height above sea level | 3 | |
| 8456707386 | Greenhouse Gases | Water Vapor (H2O), Carbon Dioxide (CO2), Methane (CH4), and Nitrous Oxide (N2O). Play a role in determining the earth's average temperature and thus its climates | 4 | |
| 8456707387 | Greenhouse Effect | The natural warming effect of the troposphere | 5 | |
| 8456707388 | Mosoons | Heavy rains that fall on continents north or south of warm oceans | 6 | |
| 8456707389 | Biomes | Large terrestrial regions, characterized by similar climate, soil, plants, and animals, regardless of where they are found in the world | 7 | |
| 8456707390 | Desert | An area where evaporation exceeds precipitation. Annual precipitation is low in these driest of the earth's biomes and is often scattered unevenly throughout the year; cover about 30% of the earth's surface | 8 | |
| 8456707391 | Grasslands/Prairies | Occur mostly in the interiors of continents in areas too moist for deserts and too dry for forests. Persist because of a combination of seasonal drought, grazing by large herbivores, and occasional fires - all of which keep large numbers of shrubs and trees from growing | 9 | |
| 8456707392 | Tropical Grasslands: Savannas | Grasslands with scattered trees and enormous herds of hoofed animals | 10 | |
| 8456707393 | Temperate Grasslands: Fertile Soils | Grasslands with cold winters and hot and dry summers have deep and fertile soils that make them widely used for growing crops and grazing cattle | 11 | |
| 8456707394 | Permafrost | Underground soil in which captured water stays frozen for more than two consecutive years | 12 | |
| 8456707395 | Forest | Occur in undisturbed areas with moderate to high average annual precipitation; contain various species of trees and smaller forms of vegetation | 13 | |
| 8456707396 | Tropical Rainforest | Heavy rainfall on most days and a rich variety of species occupying a variety of specialized niches in distinct layers | 14 | |
| 8456707397 | Temperate Deciduous Forests | Forest changes with the seasons, most of the trees in this biome survive the winter by dropping their leaves, which decay and produce a nutrient-rich soil | 15 | |
| 8456707398 | Evergreen Coniferous Forests | Forests categorized by cold winters, wet summers, and conifers. These forests consist of mostly cone-bearing evergreen trees that keep their needles year-round to help the trees survive the long and cold winters | 16 | |
| 8456707399 | Temperate Rain Forest | Coastal areas support huge cone-bearing evergreen trees such as redwoods and Douglass fir in a cool and moist environment | 17 | |
| 8456707400 | Mountains | High-elevation forested islands of biodiversity and often have snow-covered peaks that reflect solar radiation and gradually release water to lower-elevation streams and ecosystems | 18 |
