Lab #3
Coordinate System
INTRODUCTION: Please read this as it contains information required to perform the
lab and material that may be tested.
Coordinate systems are a device used to help locate points on a map, chart or globe. Each
coordinate system must utilize two points to locate a position. Latitude and longitude are
widely accepted although many others exist. Addresses are also a coordinate system.
Latitude lines, called parallels, run east and west but measure north and south of the Equator
(0o latitude). Longitude lines, known as meridians run north and south but measure east and
west of the Prime Meridian (0o longitude). If this is confusing, think of the lines on a
football field and which way you go for a first down.
Degrees of latitude and longitude are often broken into minutes and seconds. Each degree
can be split up into 60 minutes ( ' ) and each minutes divided into seconds ( " ). For instance,
this classroom is located at:
42o 44' 23" North Latitude
78o 08' 14" West Longitude
In this lab you will create your own coordinate system, work with latitude and longitude and
learn about minutes of latitude and longitude.
PART 1: The Earth Science Reference Tables contain a Surface Ocean Currents Map
(p.4) which consists of a world map with latitude and longitude lines. For questions number
1 through 5, tell what continent or ocean that point lies on.

For questions 6 through 10, give the latitude and longitude of each point to the nearest whole
degree. Be sure to specify the direction.

almost touch)
PART 2: You will need to use the map of Generalized Bedrock Geology of New York
State in your Earth Science Reference Tables (p. 3) to complete Part 3. For questions
number 1 through 5, tell what can be found at that point.
