The desert is one of the best known and easily identifiable geographic environments due to its very scarce vegetation and also due to the presence of not very fertile lands, either through sand dunes or dry land that does not allow any type of cultivation. The best-known desert in the world is the Sahara Desert, which occupies several countries in North and Central Africa and which, in terms of extension, is the largest. However, many other regions of the planet are considered desert and unsuitable for the development of human, animal or plant life.
The main characteristics of the desert have to do with the quality of its soils and with the level of rainfall that these areas receive throughout the year. Thus, we can say that what clearly differentiates deserts from other ecosystems is that they have low rainfall and therefore their soils are arid or not suitable for cultivation. At the same time, deserts have a significant temperature range, which means that while temperatures are usually very high during the day and very low at night. This also adds elements to make this space an unpleasant place for permanent life in it.
Due to these conditions, deserts are characterized by having very little vegetation as well as animals that are specific to those areas and that have particular elements to survive. However, the desert flora and fauna is very scarce, among the animal species we can mention different types of lizards, lizards, insects, scorpions, birds of prey and camels. The typical plants of deserts are cacti and palm trees as well as small shrubs that do not reach too high and that mainly serve as refuge for desert animals.
