Topographic Maps Review Quiz - Quiz

Questions and Answers
  • 1. 

    On a map, the height of an object measure from sea level is:

    • A.

      Contour

    • B.

      Elevation

    • C.

      Scale

    Correct Answer
    B. Elevation
    Explanation
    The height of an object measured from sea level is referred to as elevation. Elevation is a term used in cartography to represent the vertical distance between a point on the Earth's surface and a reference point, which is typically sea level. It is an important factor in creating accurate topographic maps and understanding the relief and terrain of a specific location.

    On a topographic map, elevation is shown by what?

    • A.

      Contour lines

    • B.

      Legend

    • C.

      Scale

    Correct Answer
    A. Contour lines
    Explanation
    On a topographic map, elevation is shown by contour lines. Contour lines are lines that connect points of equal elevation, allowing us to visualize the shape and steepness of the land. The spacing and shape of the contour lines indicate the slope and relief of the terrain. By closely examining the contour lines, we can determine the elevation of specific points on the map.

    On a globe, the imaginary line around the middle of the Earth that separates the Northern and Southern hemispheres is the:

    • A.

      Prime Meridian

    • B.

      Latitude

    • C.

      Equator

    Correct Answer
    C. Equator
    Explanation
    The equator is the correct answer because it is the imaginary line that divides the Earth into the Northern and Southern hemispheres. It is located halfway between the North and South Poles and has a latitude of 0 degrees. The equator is an important reference point for determining the climate, seasons, and time zones on Earth.

    Contour lines on a topographic map that are close together indicate that

    • A.

      The elevation is very high

    • B.

      The land is very steep

    • C.

      The land has a gentle slope

    Correct Answer
    B. The land is very steep
    Explanation
    Contour lines on a topographic map that are close together indicate that the land is very steep. This is because contour lines represent points of equal elevation on the map. When the contour lines are close together, it means that there is a rapid change in elevation over a short distance, indicating a steep slope.

  • 5. 

    Contour lines on a topographic map that are far apart indicate that

    • A.

      The elevation is very low

    • B.

      The land is very steep

    • C.

      The land has a gentle slope

    Correct Answer
    C. The land has a gentle slope
    Explanation
    Contour lines on a topographic map that are far apart indicate that the land has a gentle slope. Contour lines represent points of equal elevation, and when they are spaced far apart, it suggests that there is a gradual change in elevation over a larger distance. This indicates a gentle slope rather than a steep incline or a low elevation.

    Lines that run east-west but measure degrees north-south of the Equator are called

    • A.

      Equators

    • B.

      Longitude

    • C.

      Latitude

    Correct Answer
    C. Latitude
    Explanation
    Latitude is the correct answer because it refers to the lines that run east-west but measure degrees north-south of the Equator. Longitude, on the other hand, refers to the lines that run north-south but measure degrees east-west of the Prime Meridian. Equators, on the other hand, are the imaginary lines that divide the Earth into the Northern and Southern Hemispheres.

    Lines that run north-south and measure degrees east-west of the Prime Meridian are called

    • A.

      Prime Meridians

    • B.

      Longitude

    • C.

      Latitude

    Correct Answer
    B. Longitude
    Explanation
    Longitude lines are the lines that run north-south and measure degrees east-west of the Prime Meridian. The Prime Meridian is the line of longitude that passes through Greenwich, England, and is used as the starting point for measuring longitude. Longitude lines help in locating any point on the Earth's surface in terms of its east-west position.

    The imaginary line that separates the Eastern and Western Hemispheres is called the

    • A.

      Prime Meridian

    • B.

      Longitude

    • C.

      Equator

    Correct Answer
    A. Prime Meridian
    Explanation
    The Prime Meridian is the correct answer because it is the imaginary line that divides the Earth into the Eastern and Western Hemispheres. It serves as the starting point for measuring longitude and is located at 0 degrees longitude. The Equator, on the other hand, is the line that separates the Northern and Southern Hemispheres, while longitude is the measurement of distance east or west of the Prime Meridian.

    Contour lines make a V shape in the stream direction.  The V points in which direction?

    • A.

      Upstream

    • B.

      Downstream

    • C.

      Downhill

    Correct Answer
    A. Upstream
    Explanation
    The V shape of contour lines in the stream direction indicates that the elevation increases as you move upstream. This means that the contour lines are showing the direction of higher ground, suggesting that the V points upstream, against the flow of the stream.

    Depressions are indicated by __________ on the __________ side of the contour line.

    • A.

      Contour lines; downhill

    • B.

      Hachures; uphill

    • C.

      Hachures; downhill

    Correct Answer
    C. Hachures; downhill
    Explanation
    Hachures are short lines or strokes used on a map to indicate the presence of a depression or a low area. These lines are drawn perpendicular to contour lines and point downhill towards lower elevation. Therefore, hachures are used to represent depressions on a map and they are drawn on the downhill side of the contour line.

    Closed contours indicate a __________ or a __________.

    • A.

      Hilltop; depression

    • B.

      Hilltop; valley

    • C.

      Hilltop; flat slope

    Correct Answer
    A. Hilltop; depression
    Explanation
    Closed contours on a topographic map indicate the presence of either a hilltop or a depression. A hilltop is a high point or summit, while a depression is a low point or valley. The closed contour lines encircling these features help to distinguish them from other areas on the map.

    Contour lines can split.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Contour lines represent points of equal elevation on a topographic map. They do not split or separate from each other. Instead, they form closed loops or circles around hills, mountains, or depressions. Therefore, the correct answer is false.
