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.
