Term
 Lines of Latitude are....
Definition
 Lines that go around the globe from east to west are LINES OF LATITUDE, or PARALLELS. They tell you how far north or south of the equator you are. They are measured from the equator in degrees - everything North of the equator is labeled N and everything South of the equator is labeled S.
Term
 How many degrees are there from the equator to the (a) North Pole? (b) South Pole/
Definition
 90 ° (degrees)   There are 90 degrees from the equator to the North Pole (top of globe) and 90 degress from the equator to the South Pole (bottom of globe).
Term
 Latitude
Definition
 Latitude lines measure the distance from the equator - either north or south of the equator. Latitude lines run from east to west.
Term
 Parallels
Definition
 Lines of latitude look like circles around the globe and because they run parallel to equator, they are also called paralles
Term
 What are the usual parallels we see on a map or glibe
Definition
 Lines of parallels are usually 5°, 10°, 15° or 20° apart
Term
 What does a ship use at sea to find its location?
Definition
 An instrument that gives the ship's distance north or south of the equator
Term
 How is latitude measured?
Definition
 in degress shown by °
Term
 When would a latitude line not have a N or S after its reading?
Definition
 When it is directly on the equator
Term
 A degree of latitude is about how far on the face of the earth
Definition
 A degree of latitude is about 70 miles on the face of the earth. It is about the same number of miles anywhere on the earth.
Term
 10° N is about how many miles from the equator?
Definition
 10° is about 700 miles North of the Equator.   (1° = 70 miles so 10° = 700 miles)
Term
 How many miles apart are 10° N and 10° S?
Definition
 The distance between 10° N and 10° S = 20°. 10° = 700 miles s0   20 x 70 = 1,400 miles
Term
 What are the 4 special parallels on maps and what are they used for?
Definition
 These 4 special parallels help us locate temperature belts. They are: Tropic of Cancer 23 1/2° N Tropic of Capricorn 23 1/2° S Artic Circle 66 1/2°N Antartic Circle is 66 1/2° S
Term
 Low Latitudes
Definition
 Lands between the Tropic of Cancer 23 1/2°N and the Tropic of Capricorn 23 1/2° S. It is nearly always warm or hot in the Low Latitues.
Term
 High Latitudes
Definition
 Also known as Polar Zones.   Includes the Artic Circle 66 1/2°N in the Northern Hemisphere (top of globe) and the Antarctic Circle 66 1/2° S in the Southern Hemispere (bottom of globe).   It is very cold in these zones.
Term
 The North Pole is in the center of what circle?
Definition
 Artic Circle 66 1/2° N in the Northern Hemishere (top of the globe)
Term
 Middle Latitudes
Definition
 The area in each hemishpere between the Polar Circles and the Tropics are called the Middle Latitudes. These are the latitudes where we have four seasons. There is more land in this belt in the Northern Hemisphere than in the Southern Hemisphere. Most people live in the Middle Latitudes
Term
 What is the name given to 23 1/2° N
Definition
 Tropic of Cancer
Term
 Where is the Artic Circle?
Definition
 66 1/2° N
Term
 Where is the Tropic of Capricorn?
Definition
 23 1/2° S
Term
 Why is it important that we know about temperature zones?
Definition
 So we know where we (people) can live?
Term
 Zero or Prime Meridian
Definition
 The line that runs from the North Pole through Greenwich (in England) to the South Pole. We measure the distance of places east or west of this line. We call this distance (from the Prime Meridian) the Longitude of a place
Term
 Longitude
Definition
 Longitude is the distance East or West a location is from the Prime Meridian. Lines that go from North Pole to South Pole They are measure in degrees
Term
 In what directions do meridians run?
Definition
 meridians run North pole to South pole.
Term
 What is the highest reading of longitude?
Definition
 180° (1/2 of 360°)
Term
 To give the exact location of a place, we have to provide what information?
Definition
 Both it's longitude and its latitude so we known how far it is from the Prime Meridian and the Equator.
Term
 Why and when did nations decide to make eh Greenwich meridian the zero meridian?
Definition
 At one time every country decided on its own line from which distances were measured eart or west and it was confusing. In 1884, important nations agreed to use the same line as the "zero" longitude line and called it Prime Meridian Prime Meridian goes from North Pole through Greenwich, England to the South Pole.
Term
 Each Time Belt is how many degrees of longitude wide?
Definition
 15° Each time belt is 15° of longitude wide
Term
 How many time belts do we have in the United States and what are they called?
Definition
 In North American (united states) we have FOUR time belts. They are EASTERN, CENTRAL, MOUNTAIN and PACIFIC time.
Term
 What time belt is Philadelphia in?
Definition
 Eastern
Term
 When it is 12 noon in the Eastern Time Belt what time is in the Central Time Belt? Mountain Time Belt? Pacific Time belt?
Definition
 Eastern = 12 noon Central = 11 am Mountain = 9 am Pacific = 8am   There is 3 hours between the Eastern and Pacific Time Belts
Term
 How many continents are there and what are their names?
Definition
 7 continents: North America, South America, Europe, Africa, Asia, Australia and Antartica
Term
 What continents are in North America?
Definition
 North America, Africa, Asia and Europe
