3.1 Review

Which of the following statements is true about globes?

• Globes are convenient to carry around.
• Globes accurately represent the Earth in three dimensions.
• Globes can easily fit in your pocket.
• Globes perfectly show Earth's features.

What is the best definition of a map?

• A four-dimensional representation of the Earth.
• A flat, two-dimensional representation of Earth's surface.
• A representation of Earth's surface that is portrayed in an exact 1:1 scale.
• A tool used by cartographers.

Why do maps distort Earth's features?

• Because they are two-dimensional representations of a three-dimensional object.
• Because cartographers don’t know what they are doing.
• Because they are only estimates of what cartographers think the earth looks like.
• Because they are not drawn to scale.

Which of the following is not a common map projection?

• Mercator Projection
• Gnomonic Projection
• Polyconic Projection
• Spherical Projection

How are Mercator Projections drawn?

• It is draw as if a large cylinder of paper had been wrapped around the planet and the outlines of the continents had been projected onto the paper
• It is drawn as if a sheet of paper had been laid on a point on Earth's surface, often one of the poles.
• It is drawn as if a cone of paper had been wrapped around Earth.
• It is drawn as if a sphere was wrapped around the Earth and the outlines of the continents had been projected onto the paper.

Which of the following is not a characteristic of Mercator Projections?

• They accurately depict the extreme polar regions.
• They distort the area near the poles.
• They show directions as straight lines.
• They are a great boon to navigators at sea.

Which is not a characteristic of Gnomonic Projections?

• They accurately depict the shapes of landmasses near the center point.
• They can accurately show the shortest distance between two points
• They distort the shapes of landmasses away from the center point.
• They show directions as curved lines.

What is a characteristic of Polyconic Projections?

• Lines of latitude and longitude are curved slightly.
• Most landforms have their true shape and size in relation to each other
• They accurately depict the extreme polar regions.
• They are especially useful for mapping large areas of land that fall in the middle of latitudes.

What is a shortcoming of all three projections discussed?

• They accurately depict the shapes and sizes of landforms.
• They are not useful for navigators on land, sea, and air.
• They do not distort any landforms.
• They distort landforms the further they are to the point where the "invisible sheet of paper" touches the sphere.

Which of the following best describes latitude and longitude?

• Imaginary lines that we use to divide the planet into halves
• Grid of lines used to pinpoint locations on Earth
• Unique addresses given to each point on Earth
• All of the above
