Deserts

1.westerlies tande currents ke upar se bahte hah aur apna moisture koh dehti haa jab vah western margins par pahunchti haa toh wo dry hoti haa aur koi rain nahi karti.

2.due to cooling efeects of cold currents.

Some common plants found in desert regions include cacti, succulents like agave and yucca, desert sagebrush, creosote bush, and Joshua trees. These plants have adapted to survive in arid environments with limited water availability.

those hot winds are also known as (riyah al khamsin) or the 50th winds since they usually last about 50 days and come from hot Arabian deserts.

They store water in their trunks. Also, they don't have leaves, so water does not evaporate from them, and the cactus doesn't have to support the growth of the leaves. Spikes discourage predators from eating the plant.

The Thar Desert has low vegetation cover, so the ground heats up quickly during the day and cools rapidly at night. During the day, the desert receives intense sunlight and absorbs heat, raising temperatures. At night, without the sun's heat, the desert rapidly loses warmth, leading to cooler temperatures.

1. Mutualistic relationships between desert plants and mycorrhizal fungi help plants access scarce nutrients.
2. Desert plants and animals often rely on each other for pollination to ensure their survival.
3. Some desert animals, like the yucca moth and the yucca plant, have a mutualistic relationship where the moth pollinates the plant while laying its eggs.
4. Parasitic relationships between some desert organisms, like mistletoe plants, draw nutrients from host plants.
5. Decomposers breaking down dead plant and animal matter in the desert provide nutrients for other organisms.

Yes, snow can fall in deserts. Deserts typically have large temperature fluctuations, and in some areas, it can get cold enough for snow to form and fall, particularly at high altitudes or during certain times of the year.

Desert plants have adapted to the extremes of heat and aridity by using both physical and behavioral mechanisms.

Fish fossils are found in deserts because these regions were once covered by water bodies, such as oceans or lakes, where the fish lived. Over time, geological processes, such as tectonic movements or changes in sea level, caused these areas to dry up and become deserts. The fish fossils get preserved in the sediments that accumulate over millions of years, eventually becoming exposed through erosion.

The Kalahari Desert and the Namib Desert are the two deserts found in Southern Africa. The Kalahari Desert is a semi-arid sandy savanna, while the Namib Desert is known for its large sand dunes, including the famous Sossusvlei dunes.

The humidity in a grassland is usually moderate, like on average only around 50 to 60%.

Desert regions can experience fluctuating boundaries due to climate variability driven by factors such as temperature and precipitation changes. While some desert regions may be expanding due to factors like overgrazing and deforestation, others may be shrinking due to land reclamation efforts or natural vegetation regrowth. Overall, it is crucial to monitor desertification trends and implement sustainable land management practices to combat desertification.

The elevation of a plateau is high.

The coordinates 41 degrees 06' N 73 degrees 50' W point to a location in the Atlantic Ocean, approximately 500 miles east of Cape Cod, Massachusetts, and south of Nova Scotia, Canada.

Hot dry summers with most of the precipitation occurring in late spring to early summer, and cold snowy winters. This is different for an African veld/savannah, however, which experiences 4 to 6 months of extreme drought and 6 to 8 months of violent thunderstorms that produce massive amounts of rain.

The city near 40-45 degrees N latitude and 90-100 degrees W longitude is Chicago, Illinois, USA.

The temperature drop from 3 degrees Celsius to -7 degrees Celsius is 10 degrees.

The Great Basin Desert is located in Nevada.

Spiky plants would be yuccas, agaves, sotols, etc. Spiny plants would include the cacti and a number of other plants.

The climate does not change quickly. However, the weather can change quickly in the desert. There is little humidity to hold in heat or to slow heating. The humidity acts somewhat like a buffer to slow temperature changes. Without the humidity, the temperature can change more rapidly than in an area with higher humidity.

Mercury is a rocky planet in our solar system that experiences extreme temperature variations. During the day, its surface can reach scorching temperatures due to its proximity to the Sun, while at night, temperatures drop dramatically because Mercury has no atmosphere to retain heat.

Yes, deserts can be covered in other materials besides sand, such as gravel, rock, salt flats, or ice. Each type of desert has its own unique features and characteristics based on the type of material that covers it.

The last link in the food chain is typically apex predators, such as large carnivores like lions, sharks, or eagles. These predators are at the top of the food chain and have few or no natural predators themselves.

Sturt's Desert Pea, the Australian Floral Emblem of South Australia, is found mostly in central Australia, northwestern Australia and the northern area of South Australia. It grows best in arid woodlands, and is particularly suited to the extremes of desert temperatures. Sturt's Desert Rose, the Australian Floral Emblem of the Northern Territory, is a drought-resistant plant found in the Northern Territory and all mainland states of Australia. It grows on rocky slopes and in dry creek beds of the Northern Territory, eastern South Australia, western Queensland and NSW, and northwestern Australia. There are various species of wattle (acacia) trees, a highly adaptable plant which grows in a variety of different conditions. Mulga trees are typical arid region plants, as is spinifex grass.

Arizona's coldest temperature recorded was -40°F (-40°C) at Hawley Lake on January 7, 1971. However, it is important to note that such extreme cold temperatures are rare in the state, and typical winter lows range from 20°F to 40°F (-6°C to 4°C) in colder regions.
