For anyone who has ever been in a desert, you know how secluded, aloof and lonely the landscape can be. An oasis is a place in a desert where water comes up to the surface from deep underground. Trees and other plants grow around an oasis and animals come to eat the plants, drink and find shelter. Oases are quite intriguing to both humans and animals and simultaneously are crucial parts of an ecosystem that can be found all around the world.

What are Oasis Geological Features?

Following are the oasis geographical features that you must know to have an improved understanding of what oasis is exactly.

  • Oases are created and conserved by nature as well as by men.

  • Some man-made wells in neighbourhood oases have been maintained for generations to achieve keeping the oasis as a viable water source for travellers, livestock and locales nearby that bank on the water for survival.

  • The natural environment of the oasis also imparts itself to water conservation and preservation; the trees, shrubs and other flora that mushroom in the environment of the oasis help retain water in the ground and shade the oasis from the component around it.

  • In absence of oases, trade and travel routes would have been made almost impossible

  • Without oases, the watering and feeding of people and livestock would have been constrained.

  • Oases situated in the desert (as most are) are constantly threatened by moving sands and other weather-associated elements and are safeguarded by the shelter of trees around them.

  • Palm trees, tubers, and other plants are particularly good at securing an oasis from dangerous elements and contribute greatly to the ecosystem with their deep roots and outstanding water retention abilities.

  • We as humans are unable to live directly by a body of freshwater, but oases enable us to maintain and sustain life in the strident interior of continents around the world.

Natural Oasis

Oases that are fed by above-ground rivers, such as the Nile River, can be formed by underground aquifers and rock layers hundreds of miles away. This vital association between oases and rivers implies that water sources can be created and conserved even with no water sources visible nearby. Other oasis geological features like oceans, lakes, ponds and streams can also be sources of water in an oasis relying on the location.

What is a Desert?

The driest place present on the planet is a desert. Deserts undergo less than 250mm of rain in a year. A Desert is commonly hot in the daytime and colder at nights. There are different types of desert that range from tropical hot desert like the Sahara in North America to cold deserts such as the Gobi in Central Asia. Only animals and plants that require very less water for survival can live in a desert.

What is a Sand Dune?

Sand dune is basically the hill of sand which is created by winds as they blow across the desert. The more vigorous the wind is, the farther it will carry sand particles before they eventually fall to the ground.

Did You Know

  • Along with being a distinctive geographical feature, oases provide food, water, shelter and shade for people passing through as well to plants and animals that live in the area of the oasis.

  • Life deprived of reliable water sources together with the constant desire to travel many days between the next water sources has been a theme of trade, travel and nomadic lifestyles for ages that made oasis infamous.

  • Life in harsh climates is difficult for sustenance for many creatures on Earth, including humans, and yet numerous species of plants and animals have managed to maintain these harsh environments quite well.

FAQ (Frequently Asked Questions)

Q1. How Does an Oasis Develop?

Answer: Each and every oasis is distinct in nature and can be created contributing to certain factors. Oases can be naturally created or man-made and their water sources can arise from a few places. An oasis can be developed by an underground aquifer or river which builds enough pressure for water to trickle to the surface, forming the oasis. These natural springs and aquifers enable life to exist in harsh climates like the desert and are commonly well recognized to farmers, local herders, and travellers in the region. Water in the oasis can spring from underground or from above-ground elements like rainstorms, surface rivers and natural habitat of the oasis safeguarding the oasis zone. Above ground rivers can form underground aquifers that form oases far from the river itself, rendering the incredible nature of oases as a geographical feature.

Q2. How Does an Oasis Get Its Water?

Answer: Certain other geological factors also persuade how an oasis obtains its water. Rock layers under the Earth’s surface enable trap and channel water in pockets and through fault lines, resulting in water seeping into an oasis through the surface or into a neighbouring aquifer. Certain types of rock are befitted for water retention or passage and can aid facilitate the formation and sustenance of an oasis in the desert. In some instances, where an aquifer might not have sufficient pressure to advance to the surface, a man-made well would be constructed as the catalyst for pulling off water to the surface. This makes certain the survival of an oasis and can enable jump start a natural spring that continues to feed an oasis continuously into the future.
