| Flap 1 | Flap 2 |
| Climate is.... | Average weather over period of 30+ years |
| Areas of zonal distribution are....(6) | Polar, temperate, equatorial, mediterranian, dry topics, wet tropics |
| Zonal distribution doesnt work because....(3) | Rotating globe complicates circulation, Uneven distribution of land and sea, complications of orography |
| Earth's climate system is unique beause... | mainly having H2O in all 3 states |
| The Earth rotates every year on the..... | plane of the ecliptic |
| Earths orbit is..... | elliptical |
| When Earth is closest to sun... | perihelion |
| When Earth is furthers from the sun..... | aphelion |
| Rotates on axis which is..... | 23.5 degrees off verticle, which points at Polaris all year |
| Important dates.... | 2 solstices 2 equinoxes |
| Solar intensity is greatest at.... | sub-solar point |
| Precession.... | axis "wobbles" like spinning top (24 ka cycle) effect which hemisthere has perhelion |
| Precession proposed by | Milankovitch 1920 |
| Greenhouse gasses are.... | transparent to short wave but absorb long wave, amoujnts to 33+ K |
| Greenhouse gas compositions are.... | 66% H2O, 33% carbon dioxide |
| The termal structure of earths atmosphere.....(TSMT) | Troposhere (<, 12km), Stratoshpete (> cause of ozone, 50km), Mesosphere (<, 85km) Thermoshpere(>) |
| Changing H20 requires..... | reuires energy or releases energy (latent heat) |
| The hydrologic cycle is..... | the movement of H20 around the system |
