Question

Xeric environment is characterized by
A)Precipitation
B)Low atmospheric humidity
C)Extremes of temperature
D)High rate of vaporization

Answer 1

Hint: The area having the annual rainfall which is restricted to a certain short period of the year is known as Xeric habitat. There is no precipitation during the rest of the year and not even any surface water. Temperature is generally high during the summer in both arid and semi-arid habitats.

Complete answer
-The water vapor concentration present in the air is known as humidity.
-the moisture deficient environment is the characteristics of the xeric environment and can be seen in the desert.
-Xeric environments have very little annual precipitation, generally have a low rate of vaporization and low atmospheric humidity. It also has low temperatures at night and high during the daytime.

Additional information
Deserts and xeric shrublands- have similar characteristics for the environment around them and this is the reason that they are defined as Biome by the WWFN (World Wide Fund for Nature). The word xeric is an ancient Greek word xērós, “dry". Deserts and xeric shrublands cover around 19% of Earth's land surface area and make it the largest terrestrial biome. Ecoregions are quite vivid in such habitats in terms of annual rainfall they receive.
Extreme Temperature is a significant characteristic of many deserts. Daytime temperatures are high and the absence of clouds and no insulation makes the nights cold. The diverse climate conditions enrich an array of habitats. In such regions, Woody-stemmed shrubs and plants are found that have evolved to minimize the water loss. Diverse Animal biodiversity is also characterized in such regions.

So, the correct answer is, “ low atmospheric humidity”.

Note:
-Therefore, the low atmospheric humidity is the characteristic of the xeric environment that can easily be seen in the deserts.
-The arid climates i.e Xeric climates have a high amount of evaporation rather than precipitation.
-Little moistures are held by the sandy surfaces in deserts climate, and mostly evaporate very less amount of rainfall they receive.
-It covers 14.2% of the earth's land area.
