1.4 Introduction to Earth Assignment
For this assignment, answer the questions below that correspond to the week's reading material
.
1.
Define geography in your own words.
Geography is the study of the earth and everything encompassing it. This includes the many land masses,
the oceans that make up almost three-quarters of the planet’s surface, the living things that call earth
home, as well as the interior surfaces of earth and its surrounding atmosphere.
2.
Give an example of where you could apply the scientific method (4 points).
A.
What is the problem or question you want to answer?
I want to know which treat I’m giving my dogs is causing them to have upset stomachs.
B.
What is your hypothesis?
I think it is the Blue Buffalo salmon cookie treats causing my dogs to have upset stomachs.
C.
Explain how you could test your hypothesis.
I would test this hypothesis by removing this brand from their “line up” of treats and track their
restroom experiences.
D.
Discuss your conclusion.
I.
Was your hypothesis correct? If so, explain.
My hypothesis was correct because their stomach issues ceased once they were no
longer given those specific treats.
II.
If your hypothesis was not correct, how could you revise your hypothesis?
If I was incorrect, I would have revised the hypothesis to test a different treat in the
“line up” until the culprit had been discovered.
3.
How is a scientific theory different from how the word “theory” is often used in casual conversation?
According to the textbook, a theory in science is often based on many observations over periods of time
and these theories are assumed true as long as there have been no contradicting observations. When
talking about a theory in casual conversation, people are often referring to hypothetical situations.
4.
Latitude is an angular measurement north
or south
of the equator and varies from 0
° to 90
°. Longitude is an angular measurement east
or west
of the Prime Meridian and varies from 0
° to 180
°.

5.
Cartography
is the study, practice, and interpretation of maps. (1 point).
6.
What is the purpose of a map scale?
A map scale is a vital piece of information when interpreting maps. The scale will tell you the amount of
distance on the map and what the distance is equal to in real life. Map scales are often given as ratios or
fractions (fractional), as a representative equation (verbal), or depicted as a scale graphic on the map
(graphic).
7.
Define the three types of map scales (3 points).
According to the readings from this week, representative fractions (RF) are the most commonly found
type of map scale. RFs are written as ratios, and the numerator is always 1. Verbal descriptions are often
found on older maps. These descriptions are written as an expression (“1 cm = 10 mi”), or as a statement
(“one centimeter represents ten miles”). Graphic scales are usually depicted as scale bars which has
distance measurements marked on the map.
8.
What are contour lines?
According to the readings and videos from this week, contour lines are lines that connect points of equal
elevation on maps. The elevation will remain the same when following a contour line on a map, making
them useful for depicting terrain shape.
9.
Differentiate between conformal and equal-area map projections. According to the textbook, conformal projections preserve shape and angle but distort area. These
projections can be useful in navigation and weather cartography. Equal-area projections preserve area on
any map (in proportion to its size on Earth). Shapes can get distorted in equal-area projections, so they
are ideal for small-scale mapping with intentions to compare areas of different places on the map.
