What are the main physical features of the Sahara Desert?
The principal topographical features of the Sahara include shallow, seasonally inundated basins (chotts and dayas) and large oasis depressions; extensive gravel-covered plains (serirs or regs); rock-strewn plateaus (hammadas); abrupt mountains; and sand sheets, dunes, and sand seas (ergs).
What are the 2 most common natural resources found in the Sahara Desert?
Oil, Natural Gas and Minerals An enormous wealth of natural resources is hidden beneath the Sahara Desert. Principal among these riches are huge amounts of oil and natural gas, particularly in territory belonging to Algeria and Libya.
What are 2 facts about the Sahara Desert?
10 Facts About the Sahara Desert

What are two ways animals have adapted to the landscape of the Sahara?
They take refuge in burrows during the day, hunting and foraging primarily at night, when temperatures are lower. They have developed anatomical adaptations such as the fennec fox’s large ears, which help dissipate heat, and its hairy soles, which protect its feet.
What are 3 physical features?
Landforms, bodies of water, climate, soils, natural vegetation, and animal life are among them. Physical features are including landforms, bodies of water, terrains, and ecosystems.
What made the Sahara desert?
The rise in solar radiation amplified the African monsoon, a seasonal wind shift over the region caused by temperature differences between the land and ocean. The increased heat over the Sahara created a low pressure system that ushered moisture from the Atlantic Ocean into the barren desert.
What resources are in the Sahara?
Rich phosphate deposits exist in Morocco and Western Sahara, and smaller deposits have been found elsewhere. Fuel resources include coal, oil, and natural gas. Sources of coal include anthracite seams in Morocco and bituminous fields near Béchar.
What resources are in the Sahara desert?
The most important minerals found in the Sahara include petroleum and natural gas fields, uranium, phosphates, iron ore, and a long list of other metals.
Is the Sahara desert liveable?
Brief History. The Sahara has not always been a desert. After the last Ice Age, the landscape was left as dry and barren as it is today. However, about 10,500 years ago, a sudden onset of monsoon rains transformed the uninhabitable desert into a habitable savannah.
What landforms are in the Sahara desert?

- Dunes – Dunes are hills made of sand.
- Ergs – Ergs are large areas of sand.
- Regs – regs are flat plains that are covered with sand and hard gravel.
- Hamadas – Hamadas are hard and barren rocky plateaus.
- Salt Flats – A flat area of land covered with sand, gravel, and salt.
What are two ways in which plants have adapted to survive in the desert?
How plants adapt to arid conditions
- thick, waxy skin to reduce loss of water and to reflect heat.
- large, fleshy stems to store water.
- thorns and thin, spiky or glossy leaves to reduce water loss.
- spikes protect cacti from animals wishing to use stored water.
- deep roots to tap groundwater.
How have animals and plants adapted to the desert?

Camels often live in deserts that are hot and dry during the day, coping with wind-blown sand and cold at night. Slit-like nostrils and two rows of eyelashes to help keep the sand out of their eyes.
Which is two physical features help make parts of the Sahara Desert?
The two physical features that make the Sahara Desert more livable are the oasis and the plants.
How are plants adapted to live in the Sahara Desert?

What kind of sand is in the Sahara Desert?
They are sand dunes that stretch for hundreds of kilometers at heights of more than 300 meters. Ergs cover most of Algeria and Libya and parts of Mali and Nigeria. Ergs can contain large quantities of salt. Regs are plains of sand and gravel that make up 70% of the Sahara.
Do you know that deserts often contain large mineral deposits?
Did you know that deserts often contain large mineral deposits. Some geographical features of the Sahara are sand dunes, dry valleys, salt flats, and several mountain ranges, some of which are volcanic. The Sahara has a number of physical features, including ergs, regs, hamadas, and oases. Ergs cover 20% of the Sahara.
