2.3 2.4 flashcard Topographic Maps and Earth's Images

Front

What is a topographic map?

Back

A topographic map is a detailed and accurate graphic representation of the features of a specific area, showing elevation, terrain, and landforms.

Front

What does contour interval mean?

Back

The contour interval is the vertical distance or difference in elevation between contour lines on a topographic map.

Front

What is remote sensing?

Back

Remote sensing is the process of gathering and analyzing information about an object without physical contact with the object.

Front

What type of information is most beneficial to meteorologists from satellite images?

Back

The shape and height of clouds.

Front

What features can be identified in satellite images?

Back

Features such as rivers, mountains, deserts, and glaciers can be identified in satellite images.

Front

How do satellites collect data about Earth?

Back

Satellites collect data using sensors that detect infrared and visible radiation.

Front

What is the significance of elevation changes in topographic maps?

Back

Elevation changes indicate the steepness and shape of the terrain, which is crucial for understanding landforms.

Front

How can you determine the difference in elevation between two points on a topographic map?

Back

By subtracting the elevation of the lower point from the elevation of the higher point.

Front

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

Back

Contour lines represent areas of equal elevation, helping to visualize the terrain's shape.

Front

What does a closely spaced contour line indicate?

Back

Closely spaced contour lines indicate a steep slope.
