| Desert | An area that receives less than 25 cm of rain per year. |
| Grassland | Receives between 25 and 27cm of rain each year, and is typically populated by grasses and other non-woody plants. |
| Savanna | Receive as much as 120 cm of rain each year. Scattered shrubs and small trees grow here along with grass. |

| Tundra | This biome is an extremely cold, dry, land biome. Most of the soil is frozen all year. |
| Permafrost | Frozen soil. |
| Estuary | A habitat where the fresh water of a river meets the salt water of an ocean. |
| Intertidal Zone | The part of the shore between the highest high-tide line and the lowest low-tide line is called the intertidal zone. |
| Neritic Zone | Below the low-tide like is a region of shallow water. |
| Boreal Forest | Where coniferous trees live. Winters in these forests are very cold. |
| Deciduous Forests | Temperatures vary here throughout the year. There are many different habitats here and Deciduous trees are found here. |
| Deep Zone | Located in the open ocean below the surface zone. Where most of the water is completely dark. |
| Surface zone | Out in the open ocean, light penetrates through the water only to a depth of a few hundred meters. Algae floats in these waters and carries our photosynthesis. |
