(a) beautiful sandy area In fact, with a very few exceptions, their basal metabolic rate is determined by body size, irrespective of the climate in which they live. [19] Like arid deserts, temperatures can vary greatly in semi deserts. These also occur parallel to a strong wind that blows in one general direction. Lizards and snakes are the most numerous in arid regions and certain snakes have developed a novel method of locomotion that enables them to move sidewards and navigate high sand-dunes. It’s a place where things don’t always go the way you planned. [77] Many desert animals (and plants) show especially clear evolutionary adaptations for water conservation or heat tolerance and so are often studied in comparative physiology, ecophysiology, and evolutionary physiology. A desert is a region of land that is very dry because it receives low amounts of precipitation (usually in the form of rain, but it may be snow, mist or fog), often has little coverage by plants, and in which streams dry up unless they are supplied by water from outside the area.

[102] Other desert minerals are copper from Chile, Peru, and Iran, and iron and uranium in Australia. (b) its thick stems [114] It has been found that plant growth-promoting bacteria play a role in increasing the resistance of plants to stress conditions and these rhizobacterial suspensions could be inoculated into the soil in the vicinity of the plants. Since it does not sweat, it is able to maintain water. So in this "desert" there … An Unclean Spirit Returns 42 The Queen of the South will rise at the judgment with this generation and condemn it; for she came from the ends of the earth to hear the wisdom of Solomon, and now One greater than Solomon is here. answer choices . Desert plants maximize water uptake by having shallow roots that spread widely, or by developing long taproots that reach down to deep rock strata for ground water. They form downwind of copious sources of dry, loose sand and occur when topographic and climatic conditions cause airborne particles to settle. The North Slope of Alaska's Brooks Range also receives less than 250 mm (9.8 in) of precipitation per year and is often classified as a cold desert. (c) both (a) and (b), Question 4.

The sand streams along above the surface of the ground like a fluid, often rising to heights of about 30 cm (12 in). These belts are associated with the subtropical anticyclone and the large-scale descent of dry air moving from high-altitudes toward the poles. The air is very cold and carries little moisture so little precipitation occurs and what does fall, usually snow, is carried along in the often strong wind and may form blizzards, drifts and dunes similar to those caused by dust and sand in other desert regions. It protects the earth’s surface from the hot rays of the sun. They raise heaps of sand and deposit it as mounds. When choosing the right type of palms for a desert climate, it’s essential to consider sun exposure, humidity, and nighttime temperatures. [63][64] Nevertheless, there is some plant life in the Atacama, in the form of specialist plants that obtain moisture from dew and the fogs that blow in from the Pacific.

The smaller dune fields occupy the bottom of many of the craters situated in the Martian polar regions. The Thar Desert near the India/Pakistan border is of this type. Other water from the river is piped to urban communities but all this has been at the expense of the river, which below the extraction sites no longer has any above-ground flow during most of the year. In deserts, trees are usually absent, and shrubs or herbaceous plants … [6] Semi-deserts are regions which receive between 250 and 500 mm (10 and 20 in) and when clad in grass, these are known as steppes. They are mostly found in subtropical high-pressure belts and major continental rain shadows. They then reproduce rapidly while conditions are favorable before returning to dormancy. The largest of these deserts are found in Central Asia. [102], Oil and gas form on the bottom of shallow seas when micro-organisms decompose under anoxic conditions and later become covered with sediment. Others, such as brine shrimps, fairy shrimps and tadpole shrimps, are cryptobiotic and can lose up to 92% of their bodyweight, rehydrating as soon as it rains and their temporary pools reappear. Evaporation can concentrate minerals as a variety of evaporite deposits, including gypsum, sodium nitrate, sodium chloride and borates. When it rains, the desert becomes: The desert is a dry place where there is: 1 point A great variation in the temperatures night A great variation in day and night Great Rain A cloud cover 2 See answers The distance between their crests corresponds to the average length of jumps made by particles during saltation. [52], A large part of the surface area of the world's deserts consists of flat, stone-covered plains dominated by wind erosion. [7][8], Deserts have been defined and classified in a number of ways, generally combining total precipitation, number of days on which this falls, temperature, and humidity, and sometimes additional factors. Other desert features include rock outcrops, exposed bedrock and clays once deposited by flowing water. [26], Polar deserts such as McMurdo Dry Valleys remain ice-free because of the dry katabatic winds that flow downhill from the surrounding mountains. This prospect has proved false as it disregarded the environmental damage caused elsewhere by the diversion of water for desert project irrigation. Question: The Sahara Desert covers parts of 10 countries. The cold Humboldt Current and the anticyclone of the Pacific are essential to keep the dry climate of the Atacama. The mechanism is little understood but the particles usually have a negative charge when their diameter is under 250 μm and a positive one when they are over 500 μm.[41][42]. They are also unpleasant for humans and can cause headaches and nausea. [80], Water and carbon dioxide are metabolic end products of oxidation of fats, proteins, and carbohydrates. It has a hot desert climate (Köppen climate classification BWh), with long, extremely hot summers and short, very warm winters. [105], The desert nomads were also traders. The arctic weasel has a metabolic rate that is two or three times as high as would be expected for an animal of its size. [137] Despite its low surface atmospheric pressure (only 1/100 of that of the Earth), the patterns of atmospheric circulation on Mars have formed a sea of circumpolar sand more than 5 million km2 (1.9 million sq mi) in the area, larger than most deserts on Earth.

There is no evidence that body temperature of mammals and birds is adaptive to the different climates, either of great heat or cold. [89] Many other hot desert animals are nocturnal, seeking out shade during the day or dwelling underground in burrows. While all can be generally characterized by their extreme environmental conditions, what classifies a desert is not sand or heat, but rather the amount of annual precipitation (rain or snow) these regions receive. These grains of sand, up to about 0.5 mm (0.020 in) in diameter are jerked into the air but soon fall back to earth, ejecting other particles in the process. However, the size and harshness of the terrain meant that all supplies needed to be brought in from great distances. [14], Potential evapotranspiration supplements the measurement of precipitation in providing a scientific measurement-based definition of a desert. Fragmented strata slide down into the valleys where they continue to break into pieces due to the relentless sun by day and chill by night. The desert plants and animals need Wells are dug to extract water from the porous sandstone that lies underneath. [108], Round the rims of deserts, where more precipitation occurred and conditions were more suitable, some groups took to cultivating crops.

The people living in cities and villages do not know about deserts. In the first part of the night, as the ground radiates the heat absorbed during the day, they emerge and search for prey. It minimizes its water loss by producing concentrated urine and dry dung, and is able to lose 40% of its body weight through water loss without dying of dehydration. [102] Geologists believe that other oil deposits were formed by aeolian processes in ancient deserts as may be the case with some of the major American oil fields. [8] Explanation: riyaatmaj914 riyaatmaj914 Answer: No rain.

[114] A field trial in the Sonoran Desert which exposed the roots of different species of tree to rhizobacteria and the nitrogen fixing bacterium Azospirillum brasilense with the aim of restoring degraded lands was only partially successful. These are called "reg" in the western Sahara, "serir" in the eastern Sahara, "gibber plains" in Australia and "saï" in central Asia. (b) as lively as a bird in the Arabian sands The ripples are ephemeral and a change in wind direction causes them to reorganise. Leaching by ground water can extract ore minerals and redeposit them, according to the water table, in concentrated form. Some of the barren rock is to be found in the so-called Dry Valleys of Antarctica that almost never get snow, which can have ice-encrusted saline lakes that suggest evaporation far greater than the rare snowfall due to the strong katabatic winds that even evaporate ice.
