Earth's+Latitude+Zones,+The+Seasons,+Equinoxes

Without the Latitudes and Longitudes we wouldnt know the different places and regions of the Earth. We also wouldnt know the Seasons or what Equinoxes are. This topic explains where heat is transfered. It gives u different regions and tells you where the most heat is released into our atmophere. The United States is in the Temperate zone. in alot of the country weather conditions and temperature change according to the seasons (winter, spring, summer, fall). The Earth's rotation and revolution is what causes these seasonal changes. Earth's axis does not go up and down, it goes in a circle at a tilt of about 23.5 degrees. When the Earth rotates the north end never moves and points in the direction of the north star. Earths rotation changes over a year, then repeats. With Earths rotation the posiion of the sun appears at the very top of the sky at noon, but everyday it moves just a little. A solstice occurs on the two days a year when the sun is directly overhead at 23.5 degrees. The summer solstice for the Northern Hemisphere is on June 21st. The Northern Hemisphere is facing toward the sun at this time so it recieves more sun then the Southern Hemisphere. Days are longer in the Northern Hemisphere and shorter in the Southern Hemisphere. On December 21 the winter solstice occurs in the Norhtern Hemisphere. At this time the Northern Hemisphere is tilted away from the sun. Halfway between the solstices are 2 days called equinoxes. The equinox is the beginning of spring and autumn. In an equinox neither hemisphere is facing toward the sun. the Time of day and night are approximately the same. the Atutumnal equinox is on september 22. The vernal equinox happens on March 21. The sunlight reaches the Northern and Southern Hemispheres in equal portions. media type="custom" key="7159707" __**Earth's Latitude Zones**__ Different parts of the Earth get different amonts of sunlight because of their latitude. The latitude tells you the distance in degrees north or south of the equator. Places near the Equator are generally warmer and the farther from the equator (such as the poles) get colder. Scientists use the Lines of Latitude to mark different regions which the temperatures are generally the same (the tropic, temperate, and polar zones). The tropic zone is between 23.5 degrees south and 23.5 degrees north. It is generally warm. The temperate zone is located between 23.5 degrees north to 66.5 degrees north and from 23.5 degrees south to 66.5 degrees south. It is cooler then the tropics. The polar zones are from 66.5 degrees north to the North Pole and from 66.5 degrees south to the South Pole. Cold most all the time.
