| Question | Answer |
|---|---|
| convection current are formed by air that rises at 60 degrees north and south, the rising air cools and the water vapor condenses into precipitaion | polar cells |
| avg weather hat occurs in a given region over a long period | climate |
| weather occurs layer losest to surface densest layer of atmosphere | troposphere |
| contains ozone 16 to 50 km above surface layer above troposphere | stratosphere |
| percent of incoming sunlight that is reflected from a surface | albedo |
| maximum water vapor that can be in a given temperature | saturation point |
| lower pressure allows the rising air to expand in volume and this expansion lowers the temp of the air | adiabatic cooling |
| higher pressure forces the air to decrease in volume and this decrease raises the temperature of the air | adiabatic heating |
| this now warm dry air produces arid conditions on the leeward side of the range, forming a region | rain shadows |
| oceanic circulation pattern that drives the mixing of surgace water and deep water | thermohaline circulation |
| periodic changes in winds and ocean currents | el nino southern oscillation |
| particular combination of average temperature and annual precipitaion and contain distinctive plant growth forms that are adapted to that climate | biomes |
| producers cannot survive there so nutrients are not easily recycled into the food web region water below limnetic zone | profundal zone |
| floating algae | phytoplankton |
| deeperlayer of water that lacks sufficient sunlight of photosynthesis | aphotic zone |
| upper layer of water that receives enough sunlight to allow photosynthesis | photic zone |
| some bacteria species use energy contained in the bonds of methane and hydrogen sulfide which are both found in the deep ocean to generate energy | chemosythesis |
| reverse process when water vapor in the atmosphere condenses into liquid water energy is released | latent heat release |
| the convection currents that cycle between the equator an 30 degrees north and south in this way | hadley cell |
| large scale patterns of water circulation | gyres |
| upward movement of water toward the surface | upwelling |
| cold and treeless with low growing vegetation in winter soil is completley frozen | tundra |
| underlying subsoil that is impermeable, permanently frozen layer that prevents water draining and penetrating roots | permafrost |
