Q

What does a Equal-Area projection type do?

A

Correctly shows the size of a feature.

Note: a map cannot be equal area AND conformal

Q

How does the azimuthal projection type work?

A

An imaginary piece of paper touches the globe then is flat

Usually used for poles

Q

How does the Conical projection technique work?

A

The “peice of paper” is rolled into a cone Usually used in mid-lattitude areas (between 20-50 degrees)

Q

Which project was created by Johann Heinrich Lambert?

A

Lambert Conformal Conic Projects
1772
Standard projection for mapping large areas in the mid lattitudes - USA, Europe, and Australia
Shapes are well preserved near the standard parrallels

(He also created the Transverse Mercator Projection)

Q

What type of projection is the Mercator?

A

Cylindrical
Standard for nautical purposes - because it can represent lines of constant true direction
Distortion in areas, shapes and distances (little distortion near the equator, lots at the poles)

Generally considered conformal despite some distortion because within small areas shapes are true.

Created by Flemish Cartographer Geradus Mercador in 1569

Q

What kind of projection is the Robinson?

A

Cylindrical
Created by Arthur H. Robinson in 1960
Became more popular than the Mercator in its time, looks more like the reality.
Preffered for world maps.
More pleasing appearance but traded off distortions. It is not conformal, equal area, equidistant, or true direction

17
Q

What about the cylindrical Projection - Transverse Mercator

A

From Lambert as well.
Uses same method as Mercator, but the imaginary piece of paper touches a line of longitue instead of the equator
Better for making maps of places with north-south orientations (like south america or Chile)

18
Q

a strong ocean current that brings warm water from the Gulf of Mexico into the Atlantic Ocean. It extends all the way up the eastern coast of the United States and Canada.

A

Gulf Stream

19
Q

bands of strong wind that generally blow from west to east all across the globe. They impact weather, air travel and many other things that take place in our atmosphere.

A

Jet Strem

20
Q

fast-moving bands of thunderstorms with destructive winds. The winds can be as strong as those found in hurricanes or even tornadoes! Unlike hurricanes and tornadoes, these winds follow straight lines.

A

Derechos

21
Q

a weather pattern that occurs in the Pacific Ocean. During this time, unusual winds cause warm surface water from the equator to move east, toward Central and South America. can cause more rain than usual in South and Central America and in the United States.

A

El Niño

22
Q

winds that reliably blow east to west just north and south of the equator. The winds help ships travel west, and they can also steer storms such as hurricanes, too.

A

trade winds

23
Q

large area characterized by its vegetation, soil, climate, and wildlife.

A

biome
