World Geography 1.3

Name three tools used by geographers today.

Direct observation, aerial photographers, and sound waves

The difference between Globes and Maps.

With globes you can only look at one half of the earth at a time and because the globes represent the whole earth they do not have much detail; instead maps have a flat representation of the whole earth (or parts), but can represent the the curved surface

Mercator Projection

In this projection, he stretched the poles as long as the equator to form a map that accurately shows directions and shapes but distorts distance and size.

Mollweide Projection

Shows the correct size of land masses in relation to other land masses but distorts the shape.

Robinson Projection

The lines of latitude and longitude almost intersect at right angles except near edges.

Azimuthal Projection

Shows true compass directions ; longitude lines are straight and latitude lines are circles; distorts size and shape more as you go toward the opposite poles

How can the shortest distance between who points be a curve?

Because the earth is a sphere and you measure the two points on a map instead of a globe.

Statistic

Numerical facts and figures compiled from data.

Estimate

Educated guesses based on observations.

Census

A systematic count and study of a nation's population.

Cartography

The art of making maps.

Globe

A scale-model of the earth showing actual shapes, sizes, and locations of land masses and bodies of water ; accurately depicts the distance and direction between two points on the earth.

Map

A flat representation of the earth or parts of the earth; distorts distance, shape, and size.

Projection

A flat portrayal of the earth's surface.

Equidistant Map

Shows correct distance over a small section of the earth.

Charts

Pictorial illustrations of numerical data.

Graphs

Pictorial illustrations of numerical data.
