UNLV GEOG 103 EXAM 1: CHAPTERS 1-5
EXAM QUESTIONS AND ANSWERS
GRADED A+ 2025/2026
Geography - ANS (from geo, "Earth," and graphein, "to write") is the science that studies the
relationships among natural systems, geographic areas, human culture, and the
interdependence of all of these, over space.
Spatial analysis - ANS the nature and character of physical space and the distribution of
things within it. The unifying method of geography
5 themes - ANS Location, place, movement, region, and human-Earth relationships
Physical Geography - ANS spatial study of all the elements, processes, and systems that make
up the natural environment: energy, air, water, weather, climate, landforms, soils, animals,
plants, microorganisms, and Earth itself.
Process - ANS a set of actions or mechanisms that operate in some special order
Earth Systems Science - ANS the area of study that seeks to understand Earth as an
interacting set of physical, chemical, and biological systems.
"citizen science" - ANS volunteers participate in data collection
1 @COPYRIGHT 2026 ALLRIGHTS RESERVED.
, Scientific method - ANS traditional recipe of a scientific investigation; it can be thought of as
simple, organized steps leading toward concrete, objective conclusions
Steps:
1: observations/collect data
2: hypothesis/develop ideas
3: accept or reject the test
4: if tested over years, hypothesis becomes theory
Hypothesis - ANS a tentative explanation for the phenomena observed
scientific theory - ANS explanation constructed based on several extensively tested
hypotheses and can be reevaluated or expanded according. to new evidence
sustainablility science - ANS ability of something to be sustained - to keep going, continue, or
endure
System - ANS set of parts that make up a unified whole
Open System - ANS inputs of energy and matter flow into the system, and outputs of energy
and matter flow from the system
Closed System - ANS a system that is shut off from the surrounding environment so that it is
self-contained
Feedbacks - ANS interactions in the system that either enhance or dampen the initial
response
