Whois & Analysis for desertusa.com

A biome is a formation of plants and animals that have common characteristics due to similar climates and can be found over a range of continents.

Spanning continents, biomes are distinct biological communities that have formed in response to a shared physical climate.

"Biome" is a broader term than "habitat"; any biome can comprise a variety of habitats.

A desert is a barren area of land where little precipitation occurs and consequently living conditions are hostile for plant and animal life.

The lack of vegetation exposes the unprotected surface of the ground to the processes of denudation.

About one third of the land surface of the world is arid or semi-arid.

This includes much of the polar regions where little precipitation occurs and which are sometimes called polar deserts or "cold deserts".

Deserts can be classified by the amount of precipitation that falls, by the temperature that prevails, by the causes of desertification or by their geographical location.

An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment (things like air, water and mineral soil), interacting as a system.

These biotic and abiotic components are regarded as linked together through nutrient cycles and energy flows.

As ecosystems are defined by the network of interactions among organisms, and between organisms and their environment, they can be of any size but usually encompass specific, limited spaces (although some scientists say that the entire planet is an ecosystem).

The Southwestern United States (also known as the American Southwest) is a region of the United States which includes Arizona, the western portion of New Mexico, bordered on the east by the Llano Estacado, southern Colorado and Utah below the 39th parallel, the "horn" of Texas below New Mexico, the southernmost triangle of Nevada, and the most southeastern portion of California, which encompasses the Mojave and Colorado Deserts.
