CBSE Class 7 Geography Notes Chapter 9
Here we have provided CBSE Class 7 Geography Notes Chapter 9 for the ease of the students – A desert is an arid area with little flora and unusually high or low temperatures. There are hot deserts and cold deserts, depending on the weather.The Hot Desert Sahara
The largest desert in the world is the Sahara. It covers about 8.54 million square km. Algeria, Chad, Egypt, Libya, Mali, Mauritania, Morocco, Niger, Sudan, Tunisia, and Western Sahara are the eleven nations that are surrounded by the Sahara Desert. There are raised plateaus with bare rocky surfaces and gravel plains in the Sahara Desert. In certain instances, these rocky surfaces might be higher than 2500 metres.Climate
The environment of the Sahara Desert is harsh, sweltering, and dry. There is a brief wet season there. There are no clouds and a clear sky. In this place, moisture evaporation exceeds condensation rate. The sand and the exposed rocks heat up during the day when temperatures can reach as high as 50°C. This heat then radiates outward, heating the surrounding area. The nights might be extremely cold, with lows close to zero.Flora and Fauna
The vegetation found in the Sahara Desert consists of acacia, date palms, and cacti. There is oasis in some places; they are verdant islands encircled by date palms. There are numerous types of snakes, lizards, foxes, hyenas, jackals, scorpions, and camels among the notable animal inhabitants. High levels of aridity have left the vegetation sparse. There aren't many places for animals to feed on grasses and plants. In the valleys are groves of poplars and willows. Fruit trees that bear apples, apricots, and walnuts bloom in the summer. In Ladakh, one can see robins, redstarts, Tibetan snowcocks, ravens, and hoopoes. A few of these are birds that migrate. Ladakh is home to yaks, wild sheep, goats, and unique breeds of dogs. The purpose of raising the animals is to supply milk, meat, and hides.People
There are numerous groups of people who live in the Sahara desert and engage in diverse activities. Among them are the nomadic Bedouin and Tuareg tribes, who raise horses, camels, goats and sheep. They receive milk from these animals, hides from which they may produce leather belts, slippers, and water bottles, and hair, which is used to make mats, carpets, blankets, and clothing. They shield themselves from hot winds and dust storms by dressing in bulky robes. A permanent population is supported by the Nile Valley in Egypt and the oasis in the Sahara. Date palms are grown by the villagers since water is abundant. Additionally, crops like beans, wheat, barley, and rice are cultivated. Egypt is the home of the world-famous Egyptian cotton crop. The Sahara Desert is continuously changing due to the finding of oil. Iron, phosphorus, manganese, and uranium are among the other minerals that can be found nearby. Changes are occurring in the Sahara's cultural landscape. Superhighways straddle the old camel trails, and gleaming glass-cased business towers rise over mosques. In the salt trade, trucks are taking the place of camels. Foreign tourists are observed being guided by Tuaregs. Nomadic herders are migrating to cities in greater numbers in order to work in the oil and gas industry.The Cold Desert Ladakh
Located on the eastern side of Jammu and Kashmir, in the Great Himalayas, is a frigid desert called Ladakh. It is bounded to the north by the Karakoram Range and to the south by the Zanskar Mountains. The Indus is the most significant of the several rivers that run through Ladakh. Ladakh is home to several glaciers, including the Gangri glacier. In Ladakh, elevations range from roughly 3000 metres in Kargil to over 8,000 metres in the Karakoram. Its high altitude keeps the climate incredibly dry and frigid. The sun's heat is really noticeable at this height due to the extremely thin air. Summertime highs are just above freezing during the day and much below freezing at night. Ladakh receives as little as 10 cm of precipitation annually due to its location under the Himalayas' rain shadow. There are chilling winds and scorching sun in this place.Benefits of CBSE Class 7 Geography Notes Chapter 9
