| A | B |
| Climate | long term weather in a particular location |
| 2 factors to classify climate | temperature and precipitation |
| A | Tropical |
| Tropical | between the tropics, daily precip or wet/dry seasons, warm yr round |
| Between the Tropics | 0 - 23.5 degrees latitude |
| B | Dry/Arrid |
| Dry/Arrid | Sub-Tropical, very little precip, hot (warm to hot |
| Sub-Tropical | between 23.5 and 35 degrees latitude |
| C | Mesothermal |
| Mesothermal | Sub-Tropical to Midlatitude, Year round precip or wet/dry seasons, gets warm, but never goes below freezing |
| Midlatitude | 35 to 55 degrees latitude |
| D | Microthermal |
| Microthermal | sub-arctic, moderate to dry yr round precip, fluctuates above and below freezing |
| Sub-Arctic | 55 to 66.5 degrees latitude |
| E | Polar |
| Polar | arctic, Dry/Arrid precip, Very Cold |
| Actic | 66.5 to 90 degrees latitude |
| Interception | water being intercepted by ground water |
| Infiltration is the same as | Percolation |
| where did water come from | originated with formation of Earth, process of outgassing |
| Outgassing | volcanic eruptions gave off water vapor |
