| Differences between Climate and Weather |
|
Definition
Climate= the prevailing longterm weather conditions, influences ecosystem structure, responses to climate tend to be adaptations that affect physiology which are among the forces that drive speciation
Weather= Short term atmospheric/aquatic conditions (temp, precipitation, wind, sunlight), responses, seeking shelter from a storm, etc |

|
Definition
| temperature vs precipitation, Hadley cell, Ferrel & Polar cells |
|
|
Term
| global climates are powered by what? |
|
Definition
The Sun. The amount of solar energy reaching a given unit of Earths surface depends on the angle of the suns rays, so it varies with latitude.
High latitudes= create angle so energy has larger area to cover, less intense
Equator= the warmest because sun strikes perfectly perpendicular |

Term
| What happens when a parcel of air is warmed? |
|
Definition
| It s molecules move farther apart...it expands and thus becomes less dense than cold air causing it to rise |
