Understanding Coordinates and Mapping

What is a coordinate system?

• A coordinate system is a framework for defining the position of points in space using numerical values.

• A coordinate system is a type of mathematical equation.

• A coordinate system is a method for measuring time intervals.

• A coordinate system is a way to categorize different colors.

Name two types of coordinate systems.

• Geographic coordinates

• Cylindrical coordinates

• Cartesian coordinates, Polar coordinates

• Spherical coordinates

What is the purpose of a topographic map?

• To show political boundaries of a region.

• To provide weather forecasts for an area.

• To display population density in urban areas.

• The purpose of a topographic map is to depict the terrain and elevation of an area.

How do contour lines represent elevation on a map?

• Contour lines are used to show population density on a map.

• Contour lines represent water bodies on a map.

• Contour lines indicate temperature variations on a map.

• Contour lines represent elevation by connecting points of equal height on a map.

What is the difference between a large scale and a small scale map?

• Both large and small scale maps provide the same level of detail.

• A large scale map has more detail and covers a smaller area, while a small scale map covers a larger area with less detail.

• A small scale map has more detail and covers a smaller area.

• A large scale map covers a larger area with less detail.

Explain the term 'cartography'.

• Cartography is the study of ancient civilizations.

• Cartography is the science of weather forecasting.

• Cartography is the art and science of map-making.

• Cartography refers to the process of land surveying.

What are the key elements of a map legend?

• Grid lines, compass rose, elevation markers

• Historical context, geographical features, time zones

• Weather patterns, population density, land use types

• Symbols, descriptions, scale, color codes, patterns.

How do you determine the distance between two points on a map?

• Count the number of roads between the two points.

• Use a compass to find the direction between the points.

• Use a ruler to measure the distance on the map and convert it using the map's scale.

• Estimate the distance based on the size of the map.

What is the significance of the equator in coordinate systems?

• The equator is used to measure time zones across the globe.

• The equator is the reference line for 0 degrees latitude, dividing the Earth into Northern and Southern Hemispheres.

• The equator is the reference line for 90 degrees longitude.

• The equator is the line that marks the highest point on Earth.

Describe one cartographic technique used to represent data visually.

• Dot density maps

• Isoline maps

• 3D surface maps

• Choropleth maps
