2Maps: Making the Most of Them (pM4 & M5) map- a drawing, on a flat surface, of a part of the Earth.All maps will usually contain this information: title, key, locator map, scale, latitude & longitude, boundaries, & a compass rose.Title- tells you what kind of information the map contains.Key- also called a legend, it explains the symbols for the map.Locator map- relates the area to a larger area.
3Maps Scale- allows you to tell distances between places. Latitude and longitude- tell the exact location.Boundaries- divides different places.Compass rose- tells where north is on the map.Turn to page 608 & 609. Find the title, key, locator map, scale, latitude & longitude, boundaries, compass rose.
4An Inset Map/ Grid Insets- a main map with one or more smaller maps. Grid- Evenly spaced horizontal and vertical lines which help you locate a particular area on the map.Find an inset map in your textbookAnswer questions p. M6 & M7.
5Distance Scale p.M8Distances on maps are smaller than the real distances on Earth. Why?Distance scale- shows how much smaller the map scale is to its actual size.Usually a certain # of inches stands for miles or centimeters for kilometers.What is the distance in miles from Kaduna to Port Harcourt? Porto-Novo to N’Djumena? & Benim City to Abuja?
6Map Key p. M10To use a map you must know what its colors or symbols stand for.Cartographer- mapmakerKey- also called a legend.Describe the map key onp. 612 & 613.Do you think maps are more accurate today than in the past? Why?
7Compass Rose p. M11Compass rose- is a small drawing that shows directions on a map.Its tips point to the 4 cardinal directions (N,S,E, & W). It also shows intermediate directions.Intermediate directions- in-between directions (NE, SE, NW, & SW)Answer questions “Be a tourists in New Zealand” p. m11.
8Latitude p. M12You can locate things on earth if you know latitude & longitude.Equator- the line of latitude that runs around the center of the Earth. (0 degrees).Latitude lines show how far north or south of the equator a place is located.Latitude- lines run in a east/west direction. They are called parallels.The Equator divides the Earth into the Northern & Southern Hemispheres.Answer questions p. M12
9Tropic of CancerThe Tropic of Cancer is located at 23.5 degrees N latitude.On June 21 the sun is directly overhead the Tropic of Cancer at noon. It marks the first day of summer for the Northern hemisphere. It is the farthest the sun travels north.
10Tropic of CapricornThe Tropic of Capricorn is located at 23.5 degrees S latitude.On December 21 the sun is directly overhead the Tropic of Capricorn at noon. It marks the first day of winter for the Northern hemisphere. It is the farthest south the sun will travel.The tropics is the area from the Tropic of Cancer to the Tropic of Capricorn.
11Longitude p. M13Longitude- the vertical lines on a map that go from the North Pole to the South Pole. They are also called meridians.Prime meridian- the starting point for longitude. (Zero degrees)The prime meridian runs through Greenwich, England. It is sometimes called the Greenwich Meridian.Meridians are counted east & west from the prime meridian. The prime meridian & the international date line divides the Earth into the Western & Eastern Hemisphere.Answer questions M13
12Latitude & LongitudeMinutes and Seconds For precision purposes, degrees of longitude and latitude have been divided into minutes (') and seconds ("). There are 60 minutes in each degree. Each minute is divided into 60 seconds. Seconds can be further divided into tenths, hundredths, or even thousandths.
13International Date Line p. M13 International Date Line- halfway around the world from the prime meridian is the 180 degree meridian. Thisis the point where atmidnight a new day begins.If it is Sunday west of theline, it is Saturday to theeast of it.Why do you think the line isnot straight?Answer questions M14TuesdayMonday
14Special Purpose MapsThe 2 most common kinds of maps are political & physical maps.Political map- uses color to show nations & states.Physical map- shows natural features of the land.Special-purpose maps- have only 1 purpose, such as precipitation, crops or oil.Precipitation- moisture that falls to Earth as rain, snow, sleet, or hail.* Find a political map, physical map, and a special purpose map in you textbook.
15Product MapProduct maps- show resources, such as coal, are found where crops, such as cotton, are grown.Questionsp. M16
16Natural Resource MapNatural resource map- a map that shows resources from nature (forests, coal, iron, etc.)ForestsCoal
17Time ZonesThe sun doesn’t hit all parts of the world at the same time. When it is light in 1 part of the world, it is dark in another part.The Earth is divided into 24 time zones- one for each hour of the day.Time zones often zigzag when they cross land so that people living in the same area have the same times.We are in the Eastern Standard Time Zone.Questions M19
18Daylight Savings TimeDaylight Saving Time begins at 2:00 a.m. local time on the second Sunday in March.On the first Sunday in November areas on Daylight Saving Time return to Standard Time at 2:00 a.m.It was Ben Franklin’s idea. He wanted to put the daylight during the summer to better use.
19Why Aren’t All Maps of the Same Place Alike? It is difficult to show the curved surface of the Earth on a flat map. It is like flattening a ball.Parts of the surface will stick up, causing distortions.On most maps, the regions near the center are the most accurate. Regions farther away from the center are distorted.Compare the size of Greenland & Antarctica on different maps.
20OceansThere are 5 oceans in the world. The oceans in order from largest to smallest are:PacificAtlanticIndianSouthern (new in 2000)ArcticAbout 70% of the Earth’s surface is covered by oceans. About 97% of the Earth’s water is found in the oceans. The Southern Ocean surrounds Antarctica.
21Continents are the large land masses on the Earth Continents are the large land masses on the Earth. There are 7 continents in order from largest to smallest are:: Asia, Africa, North America, South America, Antarctica, Europe, & Australia.Greenland is a part of N. America. It is sometimes called a subcontinent.Continents
22One super continent existed about 250 million years ago before they were separated into the current continents.Fossil evidence of Pangea includes similar & identical species on continents that are now far apart.Amasia is possible future super continent that could be formed in about 250 million years by the merger of America with Asia because of ocean plates. If this happens the Atlantic will be the largest ocean.
23HemispheresA hemisphere is a half of a globe. The earth has 4 hemispheres.The Equator splits the Earth into the Northern & Southern Hemispheres.The Prime Meridian splits the Earth into Western & Eastern Hemispheres.Which continent has all 4 hemispheres?
24Orange Activity p. M21 You may work with your 3 O’clock. Find another group to double date with. (Make a group of 4)One group member will get an orange & a paper towel.Another group member will use a permanent marker to draw outlines of the continents of the world on the orange.Have a different group member peel the orange so that there is only 1 peel.A fourth group member will try to flatten the peel.Write a paragraph explaining what happened to your map on the orange. Put all group members names on it & put it your class period’s IN tray.You may divide up your orange evenly & eat it.
