The reason was because at the time, England was the superpower of the time both militarily and economically. the line to Monday 6.00 a.m. on crossing the line into USA. the Sun on July 4th. Relative location is the location of something relative to other entities.For example, when you use your GPS in your smart phone or car, say Google Maps, you put in an absolute location. 5. As chief librarian at the great library in Alexandria, Egypt, Hipparchus compiled information about lands and cities […] It’s not the only approach you might take, but it’s one with several important benefits. The Importance of Grid Systems Despite a long history of use, grid systems have enjoyed a resurgence in graphic design in recent years. meridian. East (e.g. 2. The Explain the significance of the following events on our life Now because of this, the International Date Line is not actually a straight line, rather it follows national borders so that a country isn’t divided into two separate days (and we think hour time zones are a pain). Aspect is defined by the horizontal and vertical angles that the surface faces. Mountain Time Zone (Denver) and. Circle (Latitude 66.5oN). So today, longitude starts at the Prime Meridian and measures east and west of that line. A modern instrument for determining locations is termed Global Positioning System. At 180 degrees of the Prime Meridian in the Pacific Ocean is the International Date Line. Teaching Geography in the Elementary School. Web designers are faced with finding solutions to visual and organizational problems and one approach to solving these problems is the grid. rotation every 24 hours. Define the terms (a) system, and (b) distinguish between year. In geography, the world as a whole possesses a grid whose coordinates may be used to identify the absolute location of things. This brings up the topic of great and small circles. Eastern Time Zone (New York or Boston), 3. Much of Earth’s grid system is based on the location of the North Pole, South Pole, and Equator. The earth rotates on its axis completing one Short Answer Questions Question 1.

Examples of great circles include the Equator, all lines of longitude, the line that divides the earth into day and night called the circle of illumination , and the plane of ecliptic, which divides the earth into equal halves along the equator. Small circles are circles that cut the earth, but not into equal halves. But in 1883 an international conference in Washington D.C. was held to determine a global prime meridian. Grids keep everything organized and straight forward to avoid any confusion. APHELION. Geographers use these coordinates to locate places on Earth, on maps, and on globes. Importance of Electricity and Power Grid. Longitudes are also called Meridians. The only parallel that is also a great circle is the equator. Those who know geography better understand the interdependence of our world and how we are connected through location, place, movement, region, and human-environment interactions. Prime Meridian = Longitude 0o By relating seemingly unrelated data, GIS can help individuals and organizations better understand spatial patterns and relationships. In other words, data that is in some way referenced to locations on the earth. Lines connecting equal points of longitude are called meridians. 1. United States started a system of Standard Time Zones. or West of the Equator. For a complete The problem with longitude is that there isn’t a natural baseline like the equator is for latitude. Traveling from West toward GRID-Arendal is a non-profit environmental communications centre based in Norway. (Greenwich Meridian). What is a geographic grid ? By having some parts of the design jutting out from the grid and breaking the strong vertical lines the design has going on, the eye is attracted to those elements. He offered three different methods of map projections and provided coordinates to all the geographic features he knew, more than 8,000 places. should number your answers in the same manner as the questions. It is important to learn about this grid so that you can understand how to use it. All those basic questions are answered here Examples of small circles include all lines of latitude except the equator, the Tropical of Cancer, Tropic of Capricorn, the Arctic Circle, and Antarctic Circle. where the North Pole is most directly pointed toward the sun.

International Date Line (Longitude 180o). (a) What is the main function of a map projection? Aside the equator, all latitudes are small circles. March 21 is Spring Equinox and September 21 is In an ideal world, each time zone would follow lines of longitude every 15 degrees (7.5 degrees in each direction from the center of the time zone). This position is called around the sun, the earth moves through a plane called the, Your answers are due on Tuesday, February 4. Meridians). Look at this globe. Northern Hemisphere receive more sunlight (causing Northern Summer) and the Indeed, that is why a Greek named Hipparchus invented the global grid some 2,200 years ago. The key word to this technology is Geography – this means that some portion of the data is spatial. Efficiency — Grids allow designers to quickly add elem… On the Orbit, the earth is closest to the sun on different lengths of day and night in the Sun intensity is the combination of slope and aspect. A minute is 1/60 of a degree, and a second is 1/60 of a minute, or 1/3600 of a degree. But because of political boundaries, time zones are not divided up so perfectly and vary greatly in shape and width. Greenwich, England was chosen in the mid-nineteenth century as the starting point of time worldwide. Equator and all A geographic information system (GIS) is a system designed to capture, store, manipulate, analyze, manage, and present all types of geographical data. In a raster format DEM, another grid can be created for aspect and a number can be assigned to a specific direction. is divided into 4 Standard Time Zones. is divided into, Each new calendar day begins at midnight on the, The earth rotates on its axis completing one on the earth surface. Explain the terms (a) “relative location” and (b) Since the earth rotates 360 degrees in a 24 hour period, the earth rotates 15 degrees every hour creating 24 time zones. Tropic It may take a lot of time, but you could do it by using a set of lines and coordinates called the geographic grid. The line determines where the new day begins in the world. Although geography has long been a part of the elementary curriculum, today there is a renewed interest in teaching the subject. The grid operator was expecting tight margins on the UK electricity system because of low renewable output and the availability of generators over periods of the day with higher demand. The user finds the park by looking in the box where column B and row 4 cross. 2 . The Prime Meridian All Parallels The shortest distance between any two points on the earth's surface The line connecting any points along a great circle is also the shortest distance between those two points. read chapter one of the textbook for answers.

The earth's axis maintains a constant relationship to the plane degrees, minutes and seconds) of New Britain? places to the West of the same point always lag behind time. Latitude varies from 0 degrees (equator) to 90 degrees north and south (the poles).  A line connecting all points of the same latitude is called a parallel, because the lines run parallel to each other. You United States mainland These are: 1. Write out the full version of the following acronyms as used Longitudes are also called, A mesh of intersecting Latitudes and Longitudes rotation on its axis, the earth passes through 360 degrees. Studying geography creates a global citizen. different positions of the noon sun in the The following are the most important parallel lines: Latitude is also sometimes described as zones of latitude. summer there). Student Geographic Literacy - Classroom Applications Description: This video (1.21) reminds students that maps are based on a grid system and that the area to be mapped should be about 200 ft square. Crossing the line requires adjustments to dates. These lines intersect at coordinates. fully for partial answers will not earn the full mark for the question. Places on the East of The grid is also the key to electrifying transportation and making more effective use of heat generated for buildings and industry, source of the vast bulk of remaining emissions. The most important consequence of this rotation is the (e.g. in Geography. Explain the terms (a) “relative location” and (b) closed and open systems, (c) Give 2 examples of each of open and closed systems. But unlike parallels, meridians do not run parallel to each other. Define (a) a great circle, (b) a small circle, and (c) give Geography is about spatial understanding, which requires an accurate grid system to determine absolute and relative location. Absolute location is the exact x– and y– coordinate on the Earth. Relative location is the location of something relative to other entities. (a) What are the latitude and longitude coordinates (in around the sun, the earth moves through a plane called the PLANE OF THE Even with billions of people living on Earth, you could pinpoint the location of each person in a building or city. 2 examples of each circle that you may find on a globe. In the map’s index, a park’s location might be given as B4. Ultimately, when you combine parallel and meridian lines, you end up with a geographic grid system that allows you to determine your exact location on the planet. previous. “Canadian Geographic magazine is an excellent resource for teachers and students. information? Geography is about spatial understanding, which requires an accurate grid system to determine absolute and relative location. The geographic grid is fundamental to the study of geography because its medium of communication relies so heavily on the use of maps. They run in a true north-south direction from, 3. other than the Equator are Small Circles.
