This document describes five main types of deserts: midlatitude deserts, rain shadow deserts, coastal deserts, monsoon deserts, and polar deserts. It provides details on the locations and characteristics of each type. Midlatitude deserts occur between 30-50 degrees north and south, and the Sonoran Desert is given as an example. Rain shadow deserts form on the leeward side of mountain ranges where moisture is blocked. Coastal deserts are near the Tropics of Cancer and Capricorn and affected by cold ocean currents. Monsoon deserts like the Thar and Rajasthan develop due to seasonal temperature variations between land and sea. The document also includes images of plants and animals commonly found

3.  Midlatitude deserts -
Midlatitude deserts occur
between 30° and 50° N.
and S., poleward of the
subtropical highpressure
zones. The Sonoran
Desert of southwestern
North America is a typical
midlatitude desert.
 RAIN SHADOW DESERT-
Rain shadow deserts are formed
because tall mountain ranges
prevent moisture-rich clouds
from reaching areas on the lee,
or protected side, of the range.
As air rises over the mountain,
water is precipitated and the air
loses its moisture content. A
desert is formed in the leeside
"shadow" of the range.

4.  COASTAL DESERTS -Coastal
deserts generally are found
on the western edges of
continents near the Tropics
of Cancer and Capricorn.
They are affected by cold
ocean currents that parallel
the coast.
 MONSOON DESERT - Monsoons
develop in response to
temperature variations between
continents and oceans. The
Rajasthan Desert of India and
the Thar Desert of Pakistan are
parts of a monsoon desert
region west of the ranqe.

courser,Cursorius cursor, is a well-
camouflaged desert resident
Tadpole shrimp survive dry periods as
eggs, which rapidly hatch and develop
after rain.
