Question: what are the major land features of the desert

title: Desert
text: Coastal deserts are mostly found on the western edges of continental land masses in regions where cold currents approach the land or cold water upwellings rise from the ocean depths . The cool winds crossing this water pick up little moisture and the coastal regions have low temperatures and very low rainfall , the main precipitation being in the form of fog and dew . The range of temperatures on a daily and annual scale is relatively low , being 11 ° C ( 20 ° F ) and 5 ° C ( 9 ° F ) respectively in the Atacama Desert . Deserts of this type are often long and narrow and bounded to the east by mountain ranges . They occur in Namibia , Chile , southern California and Baja California . Other coastal deserts influenced by cold currents are found in Western Australia , the Arabian Peninsula and Horn of Africa , and the western fringes of the Sahara .
