The Desert Biome. ☀️ In this biogeography video we look at the world's deserts, explain why they are that way, and what types of vegetation we can find there. One of the most extreme biomes on our world, from the Sahara to the Sonora, the Gibson to the Gobi, these are the deserts of planet Earth. 🌵

This is what the bare earth looks like, the bones of our planet revealed as the skin of vegetation is peeled back. A product of endless sunshine and drought, life yet still finds a way here, for plants to survive in these regions have gotten smart, think cacti and succulents that last through the long droughts by holding vast sums of water in their fleshy bodies, with the Saguaro Cactus of the Sonoran Desert being the biggest of all. 🌵Or there's the strange Welwitschia of the Namib, or the iconic Joshua Tree of California. The oldest of all trees can also be found in the desert mountains of that state - the Bristlecone Pine Tree.

☀️ Deserts occur over extensive parts of the continental surface of the earth, present on every continent, and are in fact the largest biome in terms of land area. They are basically subdivided into four forms, hot and cold, arid and semi-arid. The former determined by whether winter temperatures fall below freezing, the latter determined by whether there is a substantial covering of vegetation or not.

🏜 Specific deserts on our planet are among the world's most famous natural geographic entities. The Mojave Desert and Sonoran Desert of North America. The Atacama Desert of Northern Chile - the driest in the world. The bleak semi-desert of Patagonia in Southern Argentina. The Namib Desert and Kalahari Desert of Namibia. The Sahara Desert of North Africa - the largest in the world. The various deserts of the Middle-East - the Negev, Wadi Rum, the Empty Quarter to name but three. The many deserts of Iran and Pakistan such as the Baluchi. The Thar Desert of Western India. The Karakum Desert of Turkmenistan. The Taklamakan Desert of North-West China - among the most forbidding of all deserts due to its extreme aridity and freezing winter temperatures. The vast cold Gobi Desert of Mongolia. And lastly, the deserts of Australia, such as the Great Sandy Desert and the Simpson Desert, with Uluru, or Ayres Rock, at the heart of that dry continent.

🌃 Despite the aridity, humans have learned to survive here, with large cities existing in the heat and dry. Las Vegas, Phoenix and San Antonio in the USA, Monterrey in Mexico, Lima in Peru, Cairo in Egypt, Riyadh in Saudi Arabia, Abu Dhabi and Dubai in the United Arab Emirates, Baghdad in Iraq, Tehran in Iran, Karachi in Pakistan, Ulaanbaatar in Mongolia.
