Four Main Environments of the Arabian Peninsula and the Four Vegetation Zones of Africa
In the early 2000 B.C., people of Arabia were serving as middlemen in trading between the lands. The Arab traders would use camels to carry some goods through a desert in the caravans, which is a group of people traveling together for mutual protection, usually with pack animals like camels. In this section I will tell you about the environments and adaptations of the Arabian Peninsula and also vegetation zones of Africa. 
Four Main Environments of the Arabian Peninsula
Desert
The desert cover about three
quarters of the Arabian Peninsula. The desert contains vast seas of sand,plains, and plateaus which are a raised area of land. The environment of a desert is hot and dry. Summer temperatures can rise above 120 degrees Fahrenheit. Winter and nighttime temperatures can drop to below freezing. The If there is rainfall it does not rain more than three to four inches and droughts can last for years. When the rain comes it usually fall violently and sometimes causing flash floods. The desert also has sandstorms with powerful winds causing blinding sandstorms. The wind sometimes can create sand dunes that can rise eight-hundred feet into the sky. To adapt to the desert people were nomads, which is a person who moves from place to place usually searching for water and vegetation. The Arab nomads were called Bedouins, they migrated through the desert raising animals such as sheep, goats, and camels. Bedouins found a place for their herds of animals to drink and eat and they set up tents. They would move when the animals had eaten most of the vegetation. Another way people had adapted to the desert is they would use camels as transportation. People would use camels because they can survive on a desert days without water, food, and they could carry heavy supplies for long distances. People would also would wear loose fitting long clothing and cotton headdresses to protect them from dust, flies, and heat. People got a lot from their herds of animal as well including milk used to drink and make food, wool used for clothing and blankets, and they traded their animal supplies with merchants from the towns.
The Oases
The desert is covered with sections of the oases which are areas where fresh water is available and they provide plant life and shade. Oases happen in areas where water has be captured under the ground. The water goes up yo the surface as a waterhole or spring. On the wet fertile land the plant life sprouts up. Oases can rang from a couple acres to a large area. For many years nomads would travel from or to oases searching for water and vegetation. The finally realized that they could grow crops so they decided to become which is permanently settled in one place. They obtained more water for their crops by digging deep wells into the ground. People who lived on oases grew many fruits like dates, peaches and grains. The date became a valuable resource because it provided food. A lot of towns developed around the oases and became trading towns. Many farmers sedentary bartered which is another word for trade. They bartered their crops for the nomads milk, meat, and camel hair.
The Coastal Plains
Arabia's coastal plain goes along the peninsula. The coatal plain goes from five-forty miles inland and ends at an area with lots of rocky cliffs. The air is moist and rain usually falls. There are lots of riverbeds that cut through and sometimes are filled with water. There are also some natural harbors. The coastal plain is suitable for farming. People would build dams, deep wells, and used the irrigation system to bring water to dry spots to grow crops. They conserved rainwater in canals and reservoirs.  Most people were farmers in the sixth century and they would grow drops like grains fruits and vegetables. They also collected fragrant tree sap to make myrrh and frankincense whick the Europeans would use as perfumes and medicines. Traders were also on the costal plains. They would send their goods by caravans to towns like Mecca or seaports. People of the costal plain traded with merchants from places like India, East Africa, and some lands along the Red Sea and the Perain Gulf. The combonation of trade and farming led to the rise of the powerful kingdoms in southern Arabia in ancient times.
The Mountains
Along the western and southern edge Indian s of the peninsula is where Arabia's largest mountain ranges run along. They  divide the coastal plain from the desert. Arabia's mountains ranges one-thousand to twelve-thousand feet high. The mountains have very different climates. Their are moist winds that come from the Ocean bring as much as twenty inches of rain each year. Dry riverbeds cut down the sides of the mountains and fill with water during rainstorms. For thousands of years people have lived in Arabia's mountains. The mountain dwellers lived in houses made of mud brick in the sixth century and people in our region still live in this dwelling today. People farmed on the steep slopes by creating terraces which are a flat strip of ground on a hillside used for growing crops. They most likely made terraces by building a low stone wall around a narrow strip of land. Terrance enlarged the space that was usable for farming. Terrace walls also conserved water by keeping the water from running off the fields. Also farmers constructed dams and irrigation systems. They stored extra water in underground storage containers, hollowed  out trees, and leather bags. Farmers in the mountains relied on many different crops like melons and pomegranates. They also grew trees to produce frankincense and myrrh. They probably used some manure and ashes from cooking fires to fertilize the soil.
The Niger River and the Four Main Vegetation Zones of Africa
Semidesert
South of the Sahara Desert is a semidesert called Sahel. The Sahel is not as dry as the Sahara Desert. The Sahel has enough water for short grasses and some small trees and bushes.
Savanna
The southern part of the Sahel goes into the savanna. A savanna is a area of tall grasses and scattered trees. The savanna has a long rainy seasons. Rice, sorghum, and grains can be grown at a savanna because of the rain. The grass provides foods for the animals like camels, goats, sheep, and cattle. The Niger River helps make nearby land fertile. The Niger River also provides a food resource of fish.
Forest
The Niger River goes to the forest zone in West Africa. The forest is much wetter than the savanna. In the northern part of the forest it is a woodland forest, and area of abundant trees and shrubs. Yams, oil palms, and kola trees grow in the woodland forest. In the southern part of the forest there is a rain forest, and area of lush vegetation and year-round rainfall. Tall trees and teak grow above swamps and lagoons.
Desert
A desert is a geographic area with extremely warm and dry climate. In the north, West Africa begins in the Sahara Desert sands. Approximately this desert spreads 3,500,000 square miles in North Africa and the northern part of West Africa. The Sahara has bare, rocky plain and mountains. Also it has one quarter of sand dunes. Except for some scattered oases the Sahara is very, very dry. This was not a suitable place for settlements that were large.
The Effects on Trade, Gold, Salt, Food, and Slaves
There was many patterns of trade that developed that were influenced by West Africa. Trans-Saharan Trade has a very long history. Africans would bring back gold from southern forests. The introduction of the camel and the spread of Islam were the two factors that helped the growth of the trans-Saharan trade. The introduction of camels allowed traders to establish caravan trade routes across the Sahara. Large amounts of gold came from West Africa. Salt, food, and slaves were also traded. There was a place called Wangara where the gold was a secret source. There was also a place called Taghaza where the village was built with salt. In Wangara, gold was important, but in Taghaza salt was more important to them than gold. Wangara kept their gold mines secret, they would rather give up their lives than tell people where their mines were located. Taghaza would not have existed without salt because of the lack of crops. People would live to mine and sell salt. In the trading of salt and gold some people would use the silent barter system. In silent bartering one group of traders would go to a specific location or area, leaving their items or trading goods and going away from the area. Then the other group would go and look or inspect the goods which would be usually salt or gold. If the trading goods met the other traders approval the second group would go and take the goods and leave their own goods in return and leave.
