Question

Каковы причины образования Сахары и каковы особенности природы?

Answer 1

Причины образования пустыни Сахара - это неправильное ведение сельского хозяйства ( выжигание, чрезмерные выпасы скота, а также вырубка деревьев и кустарников). Только за последние полвека Сахара значительно увеличила свою площадь, продвинувшись на юг  на 650 тыс.км( в квадрате)
особенности природы это:
Флора пустыни  в основном располагается на оазисах. Это Эвимеры, Кипарисы, Мастиковые деревья и Тумбоа.
Растение Тумбоа. 2 листа которые живут и растут более 1000 лет. Листья у Тумбоа до 3 метров. По другому Тумбоа это Венвиче.

Causes of the Formation of the Sahara Desert

The formation of the Sahara Desert can be attributed to several factors. One of the primary causes is believed to be the movement of the Earth's tectonic plates, which led to the uplift of the Atlas Mountains and the subsequent disruption of the African monsoon system.

Another significant factor is the Earth's orbital parameters, particularly the changes in the tilt and precession of the Earth's axis, which have influenced the distribution of solar radiation and the intensity of the African monsoon.

Nature of the Sahara Desert

The Sahara Desert is characterized by its vast expanse, extreme aridity, and unique geological features. It spans over 9 million square kilometers, making it the largest hot desert in the world.

The climate of the Sahara is extremely arid, with very low and highly variable precipitation. The average annual rainfall is less than 100 millimeters, and some areas may not receive any rainfall for years.

The landscape of the Sahara includes sand dunes, rocky plateaus, and mountains. The desert is also home to various oasis regions, which serve as vital sources of water and vegetation.

The biodiversity of the Sahara is adapted to the harsh desert conditions. It includes a variety of plant species, such as acacia trees, date palms, and drought-resistant shrubs. The animal life in the Sahara consists of species like the dromedary camel, fennec fox, and various reptiles and insects that have evolved to survive in the desert environment.

In conclusion, the formation of the Sahara Desert is influenced by geological, climatic, and orbital factors, leading to its unique and challenging natural environment characterized by extreme aridity and specialized biodiversity.
