Geomorphology أشكال سطح الأرض

Geomorphology: the study of the physical features of the surface of the earth and their relation to its geological structures.

I always been fascinated with geomorphology, it is my father's profession. and I found a stimulating connection with architecture. Today I got a lesson from him illustrated by Google Earth, and showed me the places and what are they, here some of the great formation of God from different places in the Arabian Peninsula.

Metamorphic Rocks, Aseer:

This is an extension of volcanic rocks but melt with other kinds of earth contaminants that makes rocks like schist and basalt.

Wadi Al-Duwaser:
The valley is the greenish part, it used to be water, and now it is a green land. On the right side you can see the northern edge of The Empty Quarter.

Eastern side of the Empty Quarter:

This wonderful mixture of sand and salt that was formed by the osmosis phenomena. This is the lowest area of the empty quarter, therefore, water which comes from Oman mountains goes down to concentrate here. then it continue its osmosis process that actually goes on and on until you see it in such smooth surface as you see in the following figures.

Southern Edge of the Empty Quarter:
Here you can see the end of any water effect on sand it peacefully goes on affected by wind instead. you notice the different type of earth, here it becomes more rocky until it ends down to Yemen.

This is an image of different characteristics. They are man made fields, which are created in these circular forms because of the irrigation machine they're using, which is simply like a wheel that moves parallel to the ground, and moves horizontally like a mary-go-round and sprays water downwards. these crops are very expensive they sell it for four times their price if simply imported. but it is an encouragement for people to work on agriculture.
