The low desert of southeastern California is part of the Sonoran desert ecoregion, which extends into Arizona and parts of northern Mexico. [ 2] California has two high deserts: the Mojave desert and the Great Basin Desert. The Mojave desert ecoregion is marked by the presence of Joshua trees. [ 3] The dry cold Great Basin desert of California ...
There are three main deserts in California: the Mojave Desert, the Colorado Desert, and the Great Basin Desert. [5]: 408 The Mojave Desert is bounded by the Tehachapi Mountains on the northwest, the San Gabriel and San Bernardino Mountains on the south, and extends eastward to California's borders with Arizona and Nevada; it also forms portions of northwest Arizona.
Aridisols (or desert soils) are a soil order in USDA soil taxonomy. [1] Aridisols (from the Latin aridus, for "dry", and solum) form in an arid or semi-arid climate. Aridisols dominate the deserts and xeric shrublands, which occupy about one third of the Earth's land surface. Aridisols have a very low concentration of organic matter, reflecting ...
The ecology of the Sierra Nevada, located in the U.S. states of California and Nevada, is diverse and complex. The combination of climate, topography, moisture, and soils influences the distribution of ecological communities across an elevation gradient from 500 to 14,500 feet (200 to 4,400 m). Biotic zones range from scrub and chaparral ...
Desertification is a type of gradual land degradation of fertile land into arid desert due to a combination of natural processes and human activities. The immediate cause of desertification is the loss of most vegetation. This is driven by a number of factors, alone or in combination, such as drought, climatic shifts, tillage for agriculture ...
Caliche fossil forest on San Miguel Island, California. Caliche (/ k ə ˈ l iː tʃ iː /) - (unrelated to the street-slang "Caliche" spoken in El Salvador) - is a sedimentary rock, a hardened natural cement of calcium carbonate that binds other materials—such as gravel, sand, clay, and silt.
The result would be a transition to a different state. [1][2] In climate science, a tipping pointis a critical threshold that, when crossed, leads to large, accelerating and often irreversible changes in the climate system.[3] If tipping points are crossed, they are likely to have severe impacts on human society and may accelerate global warming.
Desert ecology is the study of interactions between both biotic and abiotic components of desert environments. A desert ecosystem is defined by interactions between organisms, the climate in which they live, and any other non-living influences on the habitat. Deserts are arid regions that are generally associated with warm temperatures; however ...
