Document Summary

Counter-wise turning on the earth"s axis (itled at 23. 5 ) The daily rhythm of how the earth receives energy (diurnal- night and day air temperature, humidity and air moion vary) Provides the day as a measure of ime (24hours = 1 full rotaion) Linked to ocean currents sun and moon have gravitaional pull to the oceans. Spherical coordinate system used to determine locaions of features on the earth"s surface. Use both laitude and longitude to pinpoint a speciic locaion along with n,s,w,e (this is what gps". Parallels (equator) never intersect do but with many satellites coming from every angle; triangulaion) Longitude: west and east of the primer meridian. Meridians ( prime meridian) converge at the poles. Measured from west and east of the primer meridian. The internaional date line is 180 both sides of this meridian are the same day just 24 hours apart (west= advance, east = go back)
