D199 Introduction to Physical and Human Geography - Set 3 - Part 1

Correct Answer: Representing data distribution using varying symbol sizes

A proportional symbol map uses symbols of different sizes to represent the density or quantity of an attribute across a geographic area.

Correct Answer: Defining units of measurement to ensure comparable data

Standardization in mapmaking ensures that different areas can be compared fairly by using the same unit of measurement for data across regions.

Correct Answer: To provide a grid for locating places using latitude and longitude

A graticule is the network of lines representing latitude and longitude on a map, helping users pinpoint specific geographic locations.

Correct Answer: They display a smaller area with more detail

Large-scale maps provide more detail and are often used for smaller areas such as neighborhoods or cities, showing more geographic features.

Correct Answer: The distribution of a specific attribute using dots

Dot density maps use dots to indicate the presence of a particular attribute, such as population or disease cases, across a geographic area.

Correct Answer: The line of longitude at 0 degrees, passing through Greenwich

The prime meridian is the 0° longitude line, running through Greenwich, UK, used as the starting point for measuring longitude.

Correct Answer: They use symbols to convey a narrative or viewpoint

Figurative maps use symbolic representations rather than focusing on exact physical accuracy, often illustrating concepts or ideas.

Correct Answer: Color variations

Choropleth maps use varying shades or colors to represent data density or values, making them ideal for visualizing differences across regions.

Correct Answer: A plane reference system using x- and y-axes

The Cartesian coordinate system uses perpendicular x- and y-axes to locate points on a plane, often applied in mathematical and spatial analysis.

Correct Answer: To flatten the Earth's surface for representation on a map

Projections in cartography involve methods for translating the Earth's curved surface onto a flat map, which often introduces some distortion.

Correct Answer: Equidistant projection

Equidistant projections maintain accurate distances from a central point, making them useful for air route maps and communication planning.

Correct Answer: A projection that breaks the map into sections, preserving area but distorting shape

Interrupted projections divide the map into sections, reducing distortion in specific areas, such as the Goode Homolosine projection.

Correct Answer: A line graph connecting points from a histogram

A frequency polygon is created by plotting the midpoints of a histogram's intervals and connecting them with a line, showing the data distribution.

Correct Answer: To represent continuous data ranges

Histograms represent the frequency of data within specified continuous ranges, often used to analyze distributions such as test scores or income levels.

Correct Answer: Flow map

Flow maps use arrows and lines of varying widths to show the movement of goods, people, or information across geographic areas.

Correct Answer: To distort size and shape based on an attribute such as population

Cartograms are distorted maps where geographic areas are resized according to the value of a particular attribute, such as population or income.

Correct Answer: Data combined from multiple sources for analysis

Aggregate data refers to information gathered from various sources and combined to provide a comprehensive analysis of trends or patterns.

Correct Answer: A variable classified into distinct categories

Categorical variables are qualitative variables that represent distinct categories, such as gender, breed of dog, or types of vegetation.

Correct Answer: To break down dead organisms and recycle nutrients

Decomposers, such as fungi and bacteria, play a vital role in ecosystems by breaking down organic material and recycling nutrients back into the environment.

Correct Answer: Data that examines the relationship between two variables

Bivariate data analyzes the relationship between two variables, such as height and weight, often using scatterplots or correlation studies.
