Alpine tundra in the North Cascades of Washington, United States. Alpine tundra does not contain trees because the climate and soils at high altitude block tree growth. [26]: 51 The cold climate of the alpine tundra is caused by the low air temperatures, and is similar to polar climate. Alpine tundra is generally better drained than arctic ...
The tundra is an extremely harsh, cold, windy, and unique ecosystem found on the extreme north and south latitudes of our Earth. The soil consists mostly of frozen permafrost, which makes it difficult for extended root systems to grow, and water to drain and support a wide variety of plant life.
Cold deserts, sometimes known as temperate deserts, occur at higher latitudes than hot deserts, and the aridity is caused by the dryness of the air. Some cold deserts are far from the ocean and others are separated by mountain ranges from the sea, and in both cases, there is insufficient moisture in the air to cause much precipitation.
The North American Deserts include both cold and hot deserts, which supply a variety of climates. Due to this fact, they are often used for agricultural, business, or petroleum purposes. These factors have been taking a toll on the desert climate, organisms, and landscape. These deserts are the Mojave, Sonoran, Chihuahuan and the Great Basin.

The Ladakh region and the city of Leh in the Great Himalayas in India also have a cold desert climate. In North America, the cold desert climate occurs in the drier parts of the Great Basin Desert and the Bighorn Basin in Big Horn and Washakie County in Wyoming. The Hautes Plaines, located in the northeastern section of Morocco and in Algeria ...
[15] There are three types of tundra: Arctic tundra, [16] alpine tundra, [16] and Antarctic tundra [17] In tundra, the vegetation is composed of dwarf shrubs, sedges and grasses, mosses, and lichens. Scattered trees grow in some tundra. The ecotone (or ecological boundary region) between the tundra and the forest is known as the tree line or ...
Many deserts, such as the Sahara, are hot year-round, but others, such as East Asia's Gobi Desert, become quite cold during the winter. [1] Temperature extremes are a characteristic of most deserts. High daytime temperatures give way to cold nights because there is no insulation provided by humidity and cloud cover. The diversity of climatic ...
