Desert Landforms Essay

1023 words - 4 pages

Desert Landforms

We were taken to an area of the desert approximately 20 kilometers
inland from Jeddah. On arrival, we were asked to carry out practical
investigations of the landforms and landscape in the immediate area,
in order to find evidence of river processes and resulting landform
such as erosion, transportation, weathering and depostion . these
investigations took place in a valley (“wadi”), which is an
intermittent watercourse, during the dry season. To carry out our
measurements, we devised the following equipment before hand:

* A clinometer, to measure the gradient along the “wadi” and its
cross profile (long profile).

* A stone board, in order to measure the size of rocks

* A chart to classify the chosen rocks

* A quadrate to help choose rocks randomly

Before leaving to the “Wadi”, we prepared a list of hypotheses. Our
aim was to prove or disprove them after collecting and analyzing our


1. the stones found at the top of the “wadi” are larger then those
at the bottom

2. the stones found at the top of the “wadi” are more angular than
those at the bottom.

3. the slope at the top of the “wadi” is “v-shaped”.

4. the slope at the bottom of the “wadi” is “u-shaped”.

5. weathering is more common at the top, as there is more exposure.

6. the angle of cross section will be smaller where the load is more

7. there is evidence of attrition taking place.

8. the smaller the stone the more rounded it is.

9. the larger the stone the more angular it is.

10. there is evidence of exfoliation (onion weathering) because of
weather condition in the desert.

11. the gradients will be greatest in the upper course and lowest in
the lower course

12. interlocking spurs can be seen

13. there is evidence of deposition in the lower course and near
the meander.

14. there is the most evidence of erosion on the stones in the lower

15. there are sign of vegetation along the course of the river

16. the angle of the cross section will be smallest in the upper
course and greatest in the lower course.

17. the load in the lower course will be small and rounded.

18. corrasion will occur more in the...

1949 words - 8 pages deserts as such illustrates how little knowledge many people in fact have of desert regions of the earth. The notion that all deserts are hot and sandy is especially erroneous. The surrounding landforms, air temperature, and soil composition have no bearing on whether or not a climate region is classified as a dessert. The sole characteristic used in classifying climate regions as a desert is aridity; a lack of moisture (Cressy 390). Deserts can be

Earth's Changing Surface Essay

1852 words - 8 pages Earth’s surface consists many different landforms. The shape of an area of land is also known as its topography. The topography of an area of land could be flat, sloping, hilly, or mountainous. Elevation, relief, and landforms determine an area’s topography. Elevation is the height above sea level. Relief is the difference in elevation between the highest and lowest parts off an area. A landform is a feature of topography formed by the process
