I love the desert , even though living conditions are hostile for most plants and animal life.
I bet it's beautiful though. What kind of animals do live there?
Not many. the lack of vegetation also exposes the surface of the ground to the processes of denudation
What is denudation?
In geology, it is the processes that wear away the Earth's surface by wind, water, etc. and that leads to landforms and landscapes of reduction of elevation
Oh okay so it's a type of erosion?
Desert
A desert is a barren area of landscape 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
erosion and denudation of land.
Overview Reasons for dryland salinity.
Dryland salinity is broadly the result of three processes: Groundwater recharge, Groundwater movement and Groundwater discharge. (Environment.nsw.gov.au, 2013)
Groundwater recharge occurs naturally, being a key process in the development of salinity, however land clearing accelerates this development as the once present deep-rooted plants do not use excess runoff, and it now seeps past the roots zone to enter the groundwater system. (Environment.nsw.gov.au, 2013) Evapotranspiration is reduced, as vegetation is lost
