Contour Intervals

What is a contour interval?

• The vertical distance between contour lines on a map.

• The angle between contour lines on a map.

• The distance between two contour lines on a map.

• The horizontal distance between contour lines on a map.

How can you determine the contour interval from a topographic map?

• Subtract the elevation of two adjacent contour lines.

• Divide the elevation of two adjacent contour lines.

• Multiply the elevation of two adjacent contour lines.

• Add the elevation of two adjacent contour lines.

Why is it important to interpret contour intervals on a map?

• To understand the topography and elevation differences on the map.

• To determine the distance between two points on the map.

• To locate the major cities on the map.

• To identify the political boundaries on the map.

What does a smaller contour interval indicate on a map?

• Greater change in elevation

• A larger map scale

• No change in elevation

• Less change in elevation

What does a larger contour interval indicate on a map?

• greater difference in elevation

• greater distance between contour lines

• smaller difference in elevation

• no change in elevation

How can contour intervals be used to identify landforms?

• Contour intervals can be used to identify landforms by showing the population density in a particular area.

• Contour intervals can be used to identify landforms by showing the elevation changes on a topographic map.

• Contour intervals can be used to identify landforms by indicating the distance from the nearest city.

• Contour intervals can be used to identify landforms by indicating the types of vegetation present.

What is the purpose of contour lines on a topographic map?

What are some common landforms that can be identified using contour intervals?

• plains

• deserts

• oceans

• mountains, valleys, ridges, cliffs, plateaus

How do contour intervals help in understanding the elevation of an area?

• Contour intervals help in understanding the elevation of an area by indicating the vertical distance between contour lines on a topographic map.

• Contour intervals help in understanding the elevation of an area by measuring the density of vegetation in different areas.

• Contour intervals help in understanding the elevation of an area by showing the temperature variations in different regions.

• Contour intervals help in understanding the elevation of an area by indicating the horizontal distance between contour lines on a topographic map.

What are some challenges in determining contour intervals accurately?

• Placing contour lines randomly without any reference to elevation

• Ignoring irregular features and focusing only on major landforms

• Using a fixed interval size for all types of terrain

• Selecting an appropriate interval size, dealing with irregular terrain or features, and ensuring consistency and accuracy in contour line placement.
