Discuss how students can see the coordinate plane as the grid mathematicians use to find slope. Slope often is used to describe the steepness of the ground's surface. When you have to use an expletive to describe a run, now thats steep.. gentle adjective. As streams merge downriver, the terrain often flattens out, and milder gradients of 3-10% slope may be measured (Figure 1.6). to classify soils, Most residual chains and individual mountains are characterized by low elevations; however, both gentle and precipitous relief can exist, depending on the degree of recent erosion. When an array of such ranges is linked together, it constitutes a mountain belt. mountain, landform that rises prominently above its surroundings, generally exhibiting steep slopes, a relatively confined summit area, and considerable local relief.

The steeper the incline, the higher the rate of soil erosion from rain runoff. (Q002) Part 2.a. Slope can be measured as the rise (the increase in elevation in some unit of measure) over the run (the horizontal distance measured in the same units as the rise). Great question! relating to high mountains, especially the mountains of the European Alps. Many geographic information systems (GIS) can analyze digital elevation data (elevation points, contour lines, digital elevation models, etc.) Kilian Jornet skis the 60-degree Troll Wall. So, change in vertical, and in this coordinate, the vertical is our Y coordinate. So slope is always a fraction. A graph of a line intersects the points zero, five and four, two.

The basic difference between north- and south-facing slopes the relative amount and intensity of sunlight they receive leads to profound ecological differences, similar (but reversed) in the Northern and Southern Hemisphere. Photo courtesy of Jackson Hole Mountain Resort. (d) Compare one of the concentric contour lines in Figure 1 with the features in Figure 2 and describe the type of terrain or landform that they indicate. So when I increase by three in the horizontal direction, I increase by six in the vertical. In the Northern Hemisphere, soil on south-facing slopes dries out faster and is warmer than soil on north-facing slopes due to longer exposure to sunlight the opposite applies in the Southern Hemisphere.
