What is topography? The height above sea level of a point on Earth’s surface. What is elevation? The difference in elevation between the highest and lowest parts of an area. What is relief? The amount of relief shown in the picture below: 5000 ft 1500 ft What is 3,500ft? These three things determine an area’s topography. What are elevation, relief and landforms? A feature of topography formed by the processes that shape Earth’s surface. What is a landform? A landform made up of flat or gently rolling land with low relief. What is a plain? A landform with high elevation and high relief. What is a mountain? A plain that lies along the sea coast. What is a coastal plain? A landform with high elevation but a relatively flat top. What is a plateau? A map that shows the feature of an area…including elevation, relief and slope. What is a topographic map? The agency in the United States that makes topo maps. What is the USGS? The most common scale on topographic maps. What is 1:24,000? These lines connect points of equal elevation. What are contour lines? Topo map symbol shown below: What is a school? These are used on topo maps to represent elevation, relief and slope. What are contour lines? The change in elevation from one contour line to another. What is the contour interval? We know that the slope is steep when contour lines are like this. What are close together? This is shown with contour lines that have dashes in the middle. What is a depression? V-shaped contour lines can indicate either of these 2 things. What is a ridge or a valley? A plain that has low relief, but the elevation can vary. They lie away from the coast. What is an interior plain? Topo map symbol shown below: What is a church? This type of slope is shown with widely spaced contours. What is a gentle slope? When the scale is 1:24,000; a cm on the map is the same as _____ cm on the surface. What is 24,000? This is represented by V-shaped contours that point downhill. What is a ridgeline?
