Desert biomes are dry climates that receive less than 50 centimeters of rain each year. Desert biomes feature one of four habitats—arid deserts, semi-arid deserts, coastal deserts and cold deserts. The desert biome covers about 20 percent of the earth's surface.Know More
Hot and dry deserts occur in low latitudes, like the Sahara in North Africa and the Chihuahuan and Mojave Deserts in North America. Vegetation and animals in dry deserts must withstand high temperatures and survive on little water. Ground-hugging shrubs and short woody trees grow in hot deserts, as do cacti, yuccas, prickly pears, agaves and brittlebush.
Temperatures during the day in semiarid deserts average between 69.8 and 80.6 F. Cooler evening temperatures reduce how much water an animal or plant loses through transpiration or sweating. The condensation of dew may equal or exceed annual rainfall of between 2 and 4 centimeters.
Coastal deserts have cool winters and warm summers and average between 8 and 13 centimeters of rain each year. Coyotes, badgers, toads, great-horned owls, golden and bald eagles, lizards and snakes live in these types of deserts, as do several types of plants, such as buckwheat bush, black bush, rice grass and chrysothamnus.
Cold winters, snowfall and rain punctuate cold deserts, such as those in the Antarctic and in Greenland. Long, cold winters follow short, moist and warm summers, with annual rainfall between 15 and 26 centimeters. Plants and animals in these deserts must withstand temperatures between 28.4 F and 78.8 F during the year. Jack rabbits, kangaroo rats, grasshopper mice, badgers and coyotes live in cold deserts, as do several varieties of sagebrush.Learn more about Earth Science
According to eSchoolToday, biomes are large ecological areas that exist on Earth’s surface. Biomes include flora and fauna and how they adapt in their specific environments.Full Answer >
The tundra biome has the shortest growing season, ranging from 50 to 60 days in the Arctic tundra to up to 180 days in Alpine tundras. Tundra biomes are distinguished by low biodiversity and domination by mosses, lichens and perennial shrubs.Full Answer >
The saltwater biome refers to the world's saltwater bodies. The saltwater biome is found all over the world, in the form of oceans, seas, bays and gulfs. More commonly called the marine biome, the saltwater biome differs in a number of important ways from freshwater biomes. Marine biomes are home to innumerable species of fish, plants, mammals, algae, bacteria and invertebrates.Full Answer >
A desert and a tundra are similar in that both of these regions receive little precipitation, have somewhat limited vegetation and experience cold temperatures at night. Along with forest, aquatic and grassland, tundra and desert are among the five major biomes on Earth.Full Answer >
