Geo chapter 1

Standard time zones

Are 15 degrees wide.

A map scale of 1:24,000 means that

One length on the map (inch, centimeter, meter) is equal to that on the ground.

A battery can be best described as a/an ____ energy system and a/an _____

Open; closed

If a system responds to a change in input by moving further away from its equilibrium condition, what type of feedback has occurred?

Positive

The increase in meltponds in arctic regions is an example of

Positive feedback, because the melt ponds absorb more solar energy than the ice did.

The letters PM stand for

Post meridian

What type of feedback maintains stability in a system, I.e., what type of feedback keeps a system functioning properly?

Negative

Geography is described as

A spatial science.

Radar is what kind of remote sensing?

Active

The letters AM stand for

After meridian

Which of the following is a capability of a geographic information system (GIS)?

Data storage, data manipulation and analysis, map production with overlays of different information layers.

The basis for defining the length of a day is the fact that

Earth rotates on its axis in 24 hours, I.e., it rotates 15 degrees of longitude per hour.

A value for earths circumference was first calculated by

Eratosthenes.

A principal methodology governing geographic inquiry

Involves spatial analysis.

How far north you live from the equator is measured as your ____, whereas an imaginary line marking all those places at that same distance north of the equator is called a _____.

Latitude, parallel.

An angular distance measures north or south of the equator from the center of earth is termed

Latitude.

The angular distance measured east or west of a prime meridian from the center of the earth is termed

Longitude.

A line connecting all points along the same longitudinal angle is called a

Meridian.

Which best describes the condition of steady-state equilibrium?

System inputs and outputs fluctuate around a stable average so the system does not move far from its average condition.

Remote sensing is

The monitoring of a distance object without physical contact.

The word spatial refers to

The nature and character of a physical place.

The inductive method of reasoning used by earth scientists to discern patterns in nature involves reasoning from

The specific to the general.

The realization that earth was a sphere

Was first made by Pythagoras, 580-500 BC.
