Sahara Desert
The Sahara Desert is the world's largest desert area. The word Sahara comes from the Arabic word sahra', meaning desert. It extends from the Africa's Atlantic Ocean side to the Red Sea and consists of the countries of Morocco, Algeria, Tunisia, Libya, Egypt, Mauritania, Mali, Niger, Chad, and Sudan. It is about 5,200 miles long. Overall, the Sahara Desert covers 3,500,000 square miles. The geography of the desert is varied. In the west, the Sahara is rocky with varied elevation. It does contain underground rivers, which sometime penetrate the surface, resulting in oases. The central region of the Sahara has more elevation than the other areas, with peaks such as Emi Koussi and Tahat. Even though the area lacks rainfall,

Plant and animal life is not as abundant in the Sahara as it is in other deserts. The grasses, shrubs, and trees that grow in parts of the Sahara have adapted in order to live in the dry conditions there. Plants of the Sahara obtain water in various ways. Some have long roots that reach deep into the soil and absorb moisture. Others take moisture from the air through their leaves. Some of the mammal species found within the Sahara are the gerbil, jerboa, Cape hare, the desert hedgehog, Dorcas gazelle, deer, common jackal, and the mongoose. The Sahara also contains over 300 species of migratory bird populations along with water and shore birds and various other types of birds. Some of the most common birds are ostriches, raptors, secretary birds, guinea fowl, desert eagles and, sand larks. Numerous types of reptiles - including frogs, toads, and crocodiles - can be found within the Sahara's lakes and pools of water, while lizards, chameleons, skinks, and cobras are to be found among the dunes and rocks. Among the reptiles in the Sahara's rivers and pools can be found snails, brine and algae shrimp, plus other types of crustaceans. Most desert animals can go for long periods of time without water. They get the water from the plants that they eat. Many of the small animals stay in their burrows during the day to avoid the heat. They search for food at night. The Sahara
Africa is the second largest of the earth's seven continents, covering about twenty-two percent of the world's total land area. From its northern most point, to its southern most tip is the distance of nearly five thousand miles. Africa is both north and south of the equator. The Atlantic Ocean is located west of the continent, and the Indian Ocean is on the east. Width of the continent is also nearly five thousand miles. Although Africa is so large, much of it is inhabitable. Desert soils, which have little organic content, cover large areas. The Sahara Desert, in the northern part, covers more than one fourth of Africa, and the Kalahari Desert is in the southern part of the continent. These two deserts are a
Surprisingly the flora and fauna is significantly low in the country. Although there is an abundance of vast open land, it is only in the areas where precipitation is high that the grasslands are thicker and heavier. One very common type of plant that grows throughout the island is the Royal palms, but overall the land has been taken over for permanent agriculture which it occupies two-fifths of the land. This is evident in the areas with fertile soils such as the valleys and low mountain slopes. Just like the plants, there are very few animal types that inhabit the land. Near the Yaque River and Lake Enriquillo you will be able to find alligators and flamingos due to the swamp like environment. Within the coral reefs you can find a small variety of fish such as yellowtail snapper and shellfish. Though there are ducks, doves, and a variety of other birds they are only seasonal visitors to the island.

Now, humans have a steady food supply so they do not have to move about. Therefore, people use fences to keep their animals in one place, which causes overgrazing. Today we see many subjects being affected by desertification. Ute Schaeffer reports the affects of desertification in, Down to Earth: News & Views on Desertification,“(doc.3) It has presented a challenge for governments and aid agencies in over 110 countries for some time, and is a contributing factor in poverty and regional conflicts, for example in Sudan. It has also been a major issue in Egypt, where 90% of the country’s land mass is desert. Faced with a rising population, the government has had to undertake a number of settlement and irrigation projects to create additional living and working space.” Necessary changes were made in order to adapt to the conditions of the desert and the obstacles that have to be faced. It is always presumed that there are only negative aspects to deserts but this isn’t always the case. There is a side to the Sahara desert that acts as a home to several living organisms. The Sahara has vegetation and access to water, which allows life to exist in this region. The Nile Valley, for example, is an area that is still quite full of foliage, trees and other growing things. This area is an exception, because of the way it is fed by the Nile River. Another area of the Sahara that has some vegetation to it is in the North, along the Mediterranean where olive trees grow
f. The music in South Africa reflects the country, and the history through the Mbube music. Either male vocalists, and or female vocalists sing such. When the lead singer is singing his or her part, they are said to be telling their stories. Mbube music is said to be traceable to furthest back the 1920’s. It was created in Africa when migrant workers begun holding singing competitions in a form of entertainment after long work days. This carried plenty of history about the country because of how old this form of music was. Dating back to the 1920’s, it was able to help preserve lots of memories, facts, and even stories about what has happened. This was mostly popular in the time that Africa was living in
In the southern margins of the Sahara Desert, going southward toward East Africa are tall, rather
In the Desert Southwest, we are blessed with two different blooming seasons, spring and fall. Roses don't really enjoy the heat of summer and go into summer dormancy, meaning that they just exist and don't grow or bloom significantly. However, with the days growing shorter and summer temperatures begin to cool, it is time to lightly prune your rose bushes, which will stimulate new growth. In September, begin by pruning back about 1/4 of the total size of the rose bush, (this isn't the major pruning that occurs in the winter). As always, prune back to an outward facing bud at an angle of 45 degrees. Seal any pruning cuts larger than the diameter of a pencil with Elmer's glue to prevent borers. It is also time to fertilize your roses in preparation
Military regimes that favor Islamic-situated governments have controlled national politics since Sudan gained freedom from Anglo-Egyptian co-rule in 1956. Sudan was entangled in two post-independence civil war amid the greater part of the rest of the twentieth century. These wars were based on the northern Muslims, Arabs economic, political, and social control of the more largely populated non-Muslim, non-Arab southern Sudanese. The first war ended with the 1972 Addis Ababa Agreement, which granted significant regional autonomy to southern Sudan on internal issues. (CIA 2015)
Egypt spans across the northeast corner of Africa and the southwest corner of Asia. The country is bordered by the Mediterranean sea and the Red Sea as well as Libya to the west, Sudan to the south, and Israel and the Gaza strip to the east. The majority of Egypt's 390,000 square miles of land lies within the Nile Valley of North Africa. Egypt has over 87 million inhabitants, making it the fifteenth most populous country in the world. Across the country, days are typically warm to hot and nights are cool. Egypt experiences a mild winter from November to April and a hot summer from May to October. The country receives very minimal rainfall throughout the year due to it’s desert climate.
Africa’s 11.7 million square miles give home to eight major physical regions. These regions range from the world’s largest desert, to the grassland Savannas, and to the densely populated rainforest (National Geographic). In addition to the numerous climates in each region, Africa is also home to volcanoes, great lakes, and the world’s tallest mountain, Mt. Kilimanjaro.
The defining character of a desert is usually low levels of rainfall with under 25 cm per year. Additional to that, the relationship between rainfall and the evaporated and transpired water must be taken into consideration. “A desert is a biological community in which most of the indigenous plants and animals are adapted to chronic aridity and periodic, extreme droughts, and in which these conditions are necessary to maintain the community’s structure” (Phillips, Comus, 2000, p. 10). This means that it is the environmental and climatic conditions that have created an evolutionary pressure for the flora to develop.
The Arab Republic of Egypt is located in the northeastern region of Africa. The climate is arid and dry and most of the country receives less than one inch of rain fall per year. The widespread lack of rainfall makes it extremely difficult to grow crops. Egypt has no forests and only 2 percent of the land is arable (land that can be farmed). The Nile was the giver of life for the ancient Egyptians. The Nile River, the longest river in the world, provided water to drink and fish like
The Nile River and nearby area is home to many animals. This includes Nile monitors, frogs, mongooses, turtles, tortoises, hippopotamus, wildebeest, baboons, over 100 species of fish, and over 300 species of birds. Many crocodiles live on the banks of the Nile, and are the largest crocodiles in
Climate: Africa contains both the world’s largest desert (the Sahara) and the world 's longest river (the Nile).Temperatures are highest in desert areas, particularly the Sahara. They are cooler across the south and in mountainous areas and plateau highlands. Rainfall varies dramatically across Africa.Changing weather patterns, however patterns of weather are changing, both locally and across the continent. The Sahara is the world 's largest low-latitude hot desert. The area is located in the horse latitudes under the subtropical ridge, a significant belt of semi-permanent subtropical, warm-core high pressure where the air from the upper levels of the troposphere tends to sink towards the ground. This steady descending airflow causes a warming and a drying effect in the upper troposphere. The sinking air prevents evaporating water from rising and, therefore, prevents the adiabatic cooling, which makes cloud formation extremely difficult to nearly impossible.
Algeria is the most populous country in northwest Africa and is the largest country, in North Africa. The northern portion of the county screeches 998 km (620 mi) along the Mediterranean Sea and borders Morocco on the west, Tunisia on the northeast, and Libya on the east. Algeria is divided into three main topographical regions, coastal plains, High Plateaus, and the desert. Unfortunately, the majority of the country consists of uninhabitable desert. “Algeria has a total land area of 2,381,741 sq km (919,595 sq mi), almost three and a
