subtropical desert

Examples of subtropical desert in the following topics:

• Subtropical Deserts and Chaparral

  • Subtropical deserts are characterized by their dry environments, while chaparrals are characterized by the presence of shrubs.
  • Subtropical deserts, which exist between 15° and 30° north and south latitude, are centered on the Tropics of Cancer and Capricorn.
  • Subtropical hot deserts may have daytime soil surface temperatures above 60°C (140°F) and nighttime temperatures approaching 0°C (32°F).
  • Subtropical deserts are characterized by low annual precipitation of fewer than 30 cm (12 in), with little monthly variation and lack of predictability in rainfall.
  • There are several types of deserts including high-pressure deserts, mid-continent deserts, rain-shadow deserts, and upwelling deserts.

• Environmental Problems Associated with Fossil Fuel Use

  • The effects of an increase in global temperature include a rise in sea levels, a change in the amount and pattern of precipitation, and a probable expansion of subtropical deserts.

• Diversity of Gymnosperms

  • Because of their attractive shape, they are often used as ornamental plants in gardens in the tropics and subtropics.
  • In tropical and subtropical zones, gnetophytes are vines or small shrubs.
  • (c) The large Welwitschia mirabilis can be found in the Namibian desert.

• Deserts

• Agricultural Settlements and Chiefdoms

  • They eventually become specialized and adapted to the continent's various ecological niches: plains, mountains, deserts, woodlands, river valleys, and coastal areas.
  • Most experts had previously believed that agriculture in the U.S. was imported from Mexico, along with the trinity of subtropical crops: maize (corn), beans, and squash.
  • The spread was so slow because the seeds and knowledge of techniques for tending them had to cross inhospitable deserts and mountains—and, possibly, because more productive varieties of maize had to be developed to compete with indigenous crops and to suit the cooler climates and shorter growing seasons of the northern regions of the continent.

• Modern Reptiles

  • Crocodilians live throughout the tropics and subtropics of Africa, South America, Southern Florida, Asia, and Australia.
  • Testudines include all shelled reptiles, such as the African spurred tortoise (Geochelone sulcata) that lives at the southern edge of the Sahara Desert.

• The Law of Unintended Consequences

  • Each major ocean basin has a large gyre in the subtropical region, centered around 30º north and south latitude.
  • The North Atlantic Subtropical Gyre is known as the Sargasso Sea.
  • The larger North Pacific Subtropical Gyre, referred to as the doldrums, is the convergence zone where plastic and other waste mixes together.

• The North Africa Campaign

  • It included campaigns fought in the Libyan and Egyptian deserts (Western Desert Campaign or Desert War), in Morocco and Algeria (Operation Torch), and Tunisia (Tunisia Campaign).
  • The Western Desert Campaign, also known as the Desert War, was the initial stage of the North African Campaign.
  • It took place in the Western Desert of Egypt and Libya beginning in September 1940 with the Italian invasion of Egypt.
  • For Adolf Hitler, the Eastern Front dwarfed the desert war, which was a holding action of secondary importance.
  • Identify the effectiveness of the Western Desert Campaign, Operation Torch, and the Tunisia Campaign.

• Rock Art in the Sahara

  • Ancient rock and cave art can be found throughout the Sahara desert, providing a significant window into the art and culture of the prehistoric peoples of Africa.
  • The region has a long history of climate change, and the desert area of today was once a savanna.
  • Located in the mountainous Gilf Kebir plateau of the Libyan Desert, the cave and rock art was discovered in 1933 by the Hungarian explorer László Almásy.
  • Tassili n'Ajjer is a mountain range in the Algerian section of the Sahara Desert.
  • Painting of men in the Cave of the Swimmers, Wadi Sura, Gilf Kebir, Western Desert, Egypt

• The North African Front

  • The North African Campaign, fought between the Allies and Axis powers, many of whom had colonial interests in Africa dating from the late 19th century, took place from 10 June 1940 to 13 May 1943, and included campaigns fought in the Libyan and Egyptian deserts, in Morocco, Algeria, and Tunisia.
  • It included campaigns fought in the Libyan and Egyptian deserts (Western Desert Campaign, also known as the Desert War) and in Morocco and Algeria (Operation Torch) and Tunisia (Tunisia Campaign).
  • The Western Desert Campaign or the Desert War, took place in the Western Desert of Egypt and Libya and was a theatre in the North African Campaign during the Second World War.
  • After the British defeats in the Balkan Campaign, the Western Desert Campaign had become more important to British strategy.
  • For Hitler the Eastern Front against the Soviet Union, dwarfed the desert war, which was a holding action of secondary importance.
