Read chapter one of the textbook for answers. The Northern Hemisphere receives less sunlight (causing winter).Īnswer the following questions. On this day, the Sun moves into the Southern Hemisphere (causing Southern Hemisphere has less Sunlight (Winter). Northern Hemisphere receive more sunlight (causing Northern Summer) and the Where the North Pole is most directly pointed toward the sun. On this day, the earth is at a position in its orbit Receive approximately 12 hours of daylight and 12 hours of darkness.
On these two days of the year, ALL PLACES on the earth March 21 is Spring Equinox and September 21 isĪutumnal Equinox.

The earth's axis maintains a constant relationship to the planeĪt an inclined angle of 23.5 0 The inclination of the axisĭuring the revolution result in three changes.Ī. On the Orbit, the earth is closest to the sun onĪround the sun, the earth moves through a plane called the PLANE OF THEĮCLIPTIC. The earth also revolves around the Sun on an Orbit The most important consequence of this rotation is the The earth rotates on its axis completing one Japan to USA), the person looses a day, Tuesday 6.00 a.m. If one travels from East towards West (from in the US immediately becomes Tuesday at 6.00 a.m. from USA to Japan) one jumps into a new day on crossing the Eastern Time Zone (New York or Boston),Įach new calendar day begins at midnight on the International Date Line (Longitude 180 o).Ĭrossing the line requires adjustments to dates. United States started a system of Standard Time Zones. In 1883, the Interstate Commerce Commission of the Places to the West of the same point always lag behind time. Places on the East ofĪ given point on the earth are therefore ahead of time while those For every 4 secondsĪ point on the earth’s surface passes through 1 degree of Longitude.ĭirection ( From West towards East). One-hour time, a point on the earth moves through 15 degrees of longitude (360/24 hours). Rotation on its axis, the earth passes through 360 degrees. The earth undergoes one complete rotation along its Other than the Equator are Small Circles.
Lines that do not pass through the center of the earth. Is attained along the arc of a Great Circle. The shortest distance between any two points on the earth's surface Is a plane that passes through the center of the earth. A modern instrument for determining locations is termed Global Geographic Grid is used to identify locations Longitudes and Latitudes are expressed in degrees,Īside the equator, all latitudes are small circles.Ī mesh of intersecting Latitudes and Longitudesĭrawn on a map produce a Geographic Grid, a Reference Grid or Graticule. Meridians help us to determine standard time. They are spaced farthest apart at the equator butĤ. They run in a true north-south direction fromģ. Each meridian is half of a great circle.Ģ.
