how does the sturts desert roses seed become a plant
When someone says it's so hot in here it feels like the Sahara desert, they are using hyperbole to emphasize how unbearably hot it is. The Sahara desert is known for its extreme temperatures, so likening a hot environment to the Sahara desert conveys the intensity of the heat experienced.
The Sahara desert used to be a rainforest, and is assumed to turn back into one another 20,000 years from now.
An unburied body could be turned to nothing but a few bones in just a few hours. Scavengers would quickly turn a body into meals. Nothing goes to waste in the desert.

Yes: this process is called "desertification". The Sahara Desert is encroaching south upon the Sahel. The catalyst to this was the drought which occurred in Africa from 1968 to 1973, and the Sahel continues to be drought-prone, which in turn increases desertification. The Sahara desert is estimated to be growing at a rate of 0.6 km every year.
There is some dispute about how the Sahara Desert could have been formed.The first view is that a sudden climate change caused the once-fertile region of the Sahara to turn to desert. Computer simulations have indicated that, over a period of just several hundred years following an abrupt climate shift some 4000 years ago, the grasslands of the Sahara gave way to the desert, while summers became longer and hotter. This belief was backed up by the presence (and age) of marine sediments in the region.The second view retains the concept that climate change caused the difference, but that it occurred much more slowly, over thousands of years rather than just hundreds. Global warming is aactually causing a renewal of green growth in some areas.Either way, climate change appears to have been the cause.
A long time
The Sahara desert is growing at an approximate rate of 0.6 kilometres outwards in each direction each year. However, the southern Sahara is growing much faster than the north due to the moistening winds of the Mediterranean. The myth that the Sahara is growing due to Global Warming is completely false. It actually occurs largely as the cause of desertification, which in turn is caused by overgrazing from African nomads' herds.
Irrigation is needed to farm in the desert.
