Chapter 1 Flashcards
Globe
A scale model of the Earth
Map
Symbolic representation of all or part of the planet
Great Circle Route
Imaginary line that follows the curve of the earth
Map projection/projection
To create maps, cartographers project the round Earth onto a flat surface. Size, shape, distance, direction may be distorted
Planar projection
Shows the earth centered in such a way that a straight line coming from the center to any other point represents the shortest distance. Also known as azimuthal projection it is the most accurate
Conic projection
Comes from placing a cone over part of a globe. They are best suited for showing limited east-west areas that are not too far from the equator. They can indicate distances and directions fairly accurate
Cylindrical projection
Based on the projection of the globe onto a cylinder. This projection is most accurate near the equator, but shapes and distances are distorted near the Poles
Winkel Tripel Projection
Most world map references. Good balance between the size and shape of land areas.
Goode’s Interrupted Equal-Area Projection
Resembles a globe that has been cut apart and laid flat. Shows true size and shape of Earth’s landmasses, but distances are generally distorted
Robinson Projection
Similar to Winkel Tripel Projection except polar areas are flattened
Mercator Projection
Increasingly distorts size and distance as it moves away from the equator. Accurately shows true directions and the shapes of landmasses, making them useful for sea travel
Grid system
Lines that cross one another forming a pattern, helps find exact places on Earth’s surface
Hemisphere
One of four halves which the Earth is divided. Helps geographers classify and describe places on Earth
Latitude
Also known as parallels, run West to East and divide North and South.
Equator
Measured at 0 degrees latitude.
