Geography 1 - Foundational Skills Flashcards
An angular distance north or south of the Earth’s equator, usually expressed in degrees and minutes.
Latitude
An angular distance east or west of the Earth’s equator, usually expressed in degrees and minutes.
Longitude
A circle on the surface of a sphere whose plane passes through the center. It represents the shortest distance between two points.
Great Circle
North, south, east, and west.
Cardinal Directions
Helps a person read a map by explaining the symbols and/or colors used on the map.
Legend
An object showing the principal directions printed on a map or chart.
Compass Rose
The relationship (or ratio) between distance on a map and the corresponding distance on the surface of the Earth.
Scale
A map that depicts land configuration, including elevation.
Relief
Collective term for lines of latitude and longitude that form an imaginary grid over Earth’s surface, making it possible to locate a specific point.
Grid System
24 longitudinal divisions of the globe, roughly 15 degrees wide, in which clocks show the same time.
Time Zones
Lines of latitude and longitude are mapped as horizontal and vertical lines. Distortion is greater in high latitudes.
Cylindrical Projections
Reduces distortion in shape and area near tangent or secant parallels.
Conic Projections
Projects onto a plane. Directions from a central point are preserved. Great circles through central point are straight lines.
Azimuthal Projections
an imaginary line about which a body rotates.
Axis
move in a circle on a central axis.
Revolve/ Revolution
A specific pairing of latitude and longitude on a coordinate grid.
Absolute Location
A system designed to capture, store, manipulate, analyze, manage, and present all types of spatial or geographical data.
GIS – Geographic Information System
A point on the earth in relation to another point or place.
Relative location
A navigation system that allows land, sea, and airborne users to determine their exact location anywhere in the world.
GPS – Global Positioning System
A set of closely grouped islands.
Archipelago
A ring of low-lying islands
Atoll
An inlet of the sea where the land curves inward
Bay
A deep, narrow valley with steep slopes, usually with a river running through it.
Canyon
A point of land that extends into the water.
