This book is about things I like to do. I get a ton of surprises at home, and especially on my birthday.
This is more than that just an about me book. If someone gives you a problematic remark about your stories that you think is more judgemental pe...
Most people think of deserts as vast expanses of sand dunes.
Is that what you think of when you think Desert?
Well deserts of rocks and stone are in fact far more common. Desert sand started out as a rock, which over the ages was weathered to form particles. The finner the particle, the farther it can be blown by wind or carried by floodwater from rare rains. Both only the rocks are left behind after the wind has carried the sand away. Water dissolves minerals such as salt, out of rocks, and these then recrystallize elsewhere.
Desert soils are composed mostly of minerals from rocks; there is little plant or animal material such as dead leaves and dung, mostly because the weather is too dry for these to be broken down to enrich the soil. Some minerals, such as oil, are hidden deep within rocks below the desert surface.
Rocky deserts..... As Elsewhere, landforms in the desert begin when rocks are thrust upward, such as during mountain building. Over countless years, the rocks are gradually weathered by heat, cold, wind, and chemical processes, In deserts, the scarce rainfall means that there are few plants to protect the soil from erosion, so landscape is angular and irregular.
When it does rain, it pours, and the torrents and floods are important in shaping the landscape: boulders and stones are carried down temporary rivers, gouging out the bedrock. Wind-borne sand scours away at the rocks, sculpting strange-looking formations. Rocks crack due to extreme variations in the daily temperatures: they expand when heated up under hot sun, only to contract during the cold nights. As they cool l, the rocks sometimes split with a loud bang. All these processes result in some of the most spectacular rock formations ever seen on Earth. Earth is already mystery enough and why can't we just breathe and taken in all that breathtaking beauty of the mystery of what happens maybe right under your feet without questions why such things happen. Why as humans is our first question most likely always why and then how? Just enjoy the Earth as it is and don't wreck it.
Only one fifth of the Sahara is covered with sand. The rest is made up of rocky desert, and gravelly or rocky plains (picture top of the page)

Mushroom Rock ......................................................... Mushroom rocks come in a variety of shapes and sizes, but all have a cap-like top on a narrower base. In a sandstorm, the wind can only bounce along the ground to a height of about 3 ft (1 m). This scours away the base of the rock, but not the top. This sandstone Mushroom Rock in the Jordanian Desert is about 26 ft (8 m) high.
