11.1 SCIENCE UNIT TEST

• A map is a two-dimensional drawing that can be used on flat surfaces and can be

  easily carried.
• a globe is a three-dimensional representation of the

  spherical shape of Earth.
• These imaginary lines form a grid collectively known as the

  geographic coordinate system.
• Lines that run horizontally from east to west are called latitudes.
• The latitude that cuts the Earth in half

  is called the equator.
• Lines that run from north to south are called longitudes.
• The longitude that passes through

  Greenwich, England is called the prime meridian.
• The degree increases as it moves westward or eastward until it

  reaches the longitude opposite to the prime meridian, the antemeridian (read as 180o

  longitude).
• The GPS receiver will be able to determine its own location based on the data received.
• The latitude and longitude are imaginary lines used to determine the exact

  coordinates of a place on Earth.
• GPS stands for global positioning system
