Weather most often results from temperature differences from one place to another。On large scales,temperature differences occur because areas closer to the equator receive more energy per unit area from the Sun than do regions closer to the poles。On local scales,temperature differences can occur because different surfaces (such as oceans,forests,ice sheets,or man-made objects) have differing physical characteristics such as reflectivity,roughness,or moisture content。
