The Deserts of Africa: The Sahara Desert

Imagine living in vibrant land, various trees and vegetation, and various kinds of animals that call this land home. We have various deserts all over the world. The life we ​​know is always different from place to place. But to learn, we will focus on some of the world's most hidden places on Earth. It will lead us through the Atlantic to one of the world's largest oceans to the continent of Africa.

There is a desert on every continent. Most of the western part of the United States is a desert. The desert zone, known as inland, covers the central part of Australia. The southern tip of South America is primarily desert. The Sahara Desert covers North Africa, a desert of the same size as the North American continent. The Arabian peninsula between the Persian Gulf and the Red Sea is almost completely dessert. From China to the Caspian Sea, the majority of Central Asia is primarily desert. The desert covers 1/8 of our planet. Aquatic plants are plants that adapt to the dry environment by planting very long roots and allow you to get water underground water or underground. Other desert plants using adaptive behavior developed a lifestyle in conjunction with the maximum moisture and the coolest temperature season. These kinds of plants are often called perennial plants, plants that can only survive for a few years, and annual plants, plants that live for a year.

Despite the general concept of dry desert and hot desert, there is a cold desert. The world's largest hot desert, the Sahara desert in North Africa has a daytime temperature of 122 degrees F (50 degrees C). However, some deserts are always cold, such as the Gobi desert in Asia and the desert in Antarctica. There are many mountains in others. Only about 10% of the desert is covered with sand dunes. Desert animals have adopted several ways to help keep the body cool and reduce water consumption. For example, a camel can be used for days without food and water. Many desert animals are night-time creatures and are intended to hunt only when cruel sun sets. Some animals, such as the tortoise of the desert in the southwestern part of the United States, are mostly in the basement. Most desert birds are nomads and intersect in the process of finding food. Due to their very special adaptability, desert animals are very sensitive to the introduction of predators and habitats.

Because the Sahara Desert occupies nearly 10% of the African continent, the Sahara Desert is often regarded as the world's largest desert. However, as it is the hottest desert in the world, this is not entirely true. According to the definition of the desert as an area of ​​desert annual rainfall less than 10 inches (250 mm), the world's largest desert is actually Antarctica. The Sahara covers some African countries, including Algeria, Chad, Egypt, Libya, Mali, Mauritania, Morocco, Niger, Sudan and Tunisia. The majority of the Sahara Desert has not been developed yet and the terrain is also diverse. Most of that landscape forms winds over time, such as sand dunes, sandy seas called Elg, barren stone plateaus, gravel plains, dry valleys, and salt plains. Approximately 25% of the desert is a sand dune, some of which are over 500 feet (152 meters) high.
