In this video Paul Andersen explains how contour lines show areas of equal elevation or equal gravitational potential. Contour lines are used as an analogy for lines of equipotential in electric fields.

Pupil outcome: I can use contour lines on OS maps to describe the height and shape of the land. Key learning points: - Contours show the height of the land on a map. - Spot heights give the exact height of a place in metres. - Contours...

Pupil outcome: I can use contour lines to identify and describe physical features on a map. Key learning points: - The height of the land can be shown on a map using spot heights and contour lines. - The shape of the land can be shown on...

We've looked at a few simple examples of first-order differential equations and how to solve them. Now let's take a look at exact first-order differential equations.

In this video students learn how to analyze and interpret data from maps to describe Earth’s surface. Students will learn how to work with topographical maps to identify features on Earth. This program addresses the following Next...

This video will examine the different features of the earth’s surface and how to identify them using a topographic map.

Upon viewing the Reading Maps video series, students will be able to do the following: Appreciate some of the different ways maps can be used. Explain that maps are often printed on paper and a book of maps is called an atlas....

The video explains how to use a topographic map. It shows how contour lines on the map indicate changes in elevation and how the distance between them can be used to determine the steepness of a slope.<b<br/>r/>
