Q

Azimuthal (Planar) Projection Definition

A

Cartographers use azimuthal projections to show polar regions because azimuthal maps are most accurate at the center

Q

Conic Projection Definition

A

If you placed a cone over a globe so it covered about half the globe, and then the images on the globe “jumped” onto the surface of the cone, you’d have a conic map projection. Conic projection maps are most accurate around the circle where the globe and cone touch

Q

Why do sailors like the Mercator Projection

A

Sailors like to use Mercator maps because a line connecting two points on a Mercator map gives the best indication of the compass direction to follow

Q

What is the problem with the Mercator Map

A

The size of the landmasses far from the equator are very badly distorted (For Example Greenland is much bigger than it really is)

Q

What is the problem with the Robinson Projection

Q

What does the Goode’s Interrupted Homosoline Projection do

A

Interrupted projections show the surface of the Earth in segments. The main advantage of an interrupted projection is that it minimizes distortion of the scale and shape of landforms

Q

What is the negative of the Goode’s Interrupted Homosoline Projection

A

The disadvantage of the Goode’s Interrupted Homosoline Projection is that it breaks Antarctica and the oceans into pieces

18
Q

What type of projection is the Goode’s Interrupted Homosoline Projection

A

Cylindrical Projection

19
Q

What does the Miller Projection do

A

It avoids scale exaggerations

20
Q

Why do Mapmakers use the Miller Projection

A

To represent the entire Earth in a rectangular frame, mapmakers frequently use the Miller projection (sometimes called the Miller cylindrical projection)

21
Q

What features are found in the Miller Projection

A

It has straight meridians and parallels that meet at right angles

22
Q

What is the negative of the Miller Projection

A

Distorts shapes and sizes and distortion is extreme in high latitudes as is evident with Antarctica

23
Q

What type of projection is the Miller Projection

A

Cylindrical Projection

24
Q

What is the Mollweide Projection

A

The Mollweide projection is an equal-area projection. It has an elliptical shape

25
Q

Who made the Mollweide Projection

A

German mathematician Carl B. Mollweide devised it in 1805

26
Q

What is the positive of the Mollweide Projection

A

The size of landforms is accurate

27
Q

What is the negative of the Mollweide Projection

A

The shapes near the edges are distorted

28
Q

What type of projection is the Mollweide Projection

A

Cylindrical Projection

29
Q

Who designed the Winkel Tripel Projection

A

Another German, Oswald Winkel, designed the Winkel Tripel projection

30
Q

How does the Winkel Tripel Projection lessen distortions

A

It lessens distortions of scale and shape by presenting the central meridian and equator as straight lines. All other parallels and medians are curved lines

31
Q

What is the Winkel Tripel Projection

A

An elliptical, equal-area projection

32
Q

What type of projection is the Winkel Tripel Projection

A

Cylindrical Projection

33
Q

Orthographic Projection Definition

A

This projection, known to the Greeks and Egyptians 2,000 years ago, is an azimuthal, or planar, projection. The Orthographic is used for perspective views of the Earth, moon, and other planets. Earth appears as it would on a photograph from deep space. This projection is sometimes used for maps of polar regions

34
Q

What type of projection is a Orthographic Projection Definition

A

Azimuthal (Planar) Projection

35
Q

Lambert Conformal Conic Definition

A

This conic projection, one of the most widely used map projections in the United States today, is used to show a country or region that has a mainly east-west orientation. Directions are reasonably accurate, and distortion of shapes and areas is minimal

36
Q

What type of Projection is the Lambert Conformal Conic

A

A Conic Projection

37
Q

Century Definition

A

A period of 100 years

38
Q

Decade Definition

A

A period of 10 years

39
Q

Millennium Definition

A

A period of 1000 years

40
Q

Millennium Plural

A

Millenia

41
Q

Does A.D go before or after the date

A

Before the date, this is because this is an Old Latin Convention still used today and only applies to A.D
