Desert – Environmental Conditions
• The desert is an area of extremes; very dry, very
  isolated and very hot. It can be cold at night (in the
  winter), windy (in the summer).
• It can be over 100 degrees Farenheit during the day
  and drop below 32 degrees Farenheit at night.
• It doesn’t usually rain in the desert, but when it rains,
  there might be a storm.
• Because the weather is very hot, the rain might
  become vapor before it reaches the ground.
• Deserts can be sandy, stony or covered in pebbles.
Desert – Animals
               CAMELS
       • Camels close their eyes
         and nostrils to keep out
         blowing sand and dust.
       • Camels store fat in their
         hump, and they can stay 3
         to 5 days without food or
         water

                 Desert - Plants
• Desert Plants should adapt to store water. They store
  water in the roots, stems, leaves or fruit.
• Some plants have long roots that reach the
  underground water deep in the ground.
• Other plants have developed spreading root systems,
  which means that the roots are a bit below the
  ground, and they are spread widely. In this way,
  when it rains in the desert, the plant is able to collect
  water.

  Human Activity Affecting the Desert
• Human activity are not only affecting the desert,
  but they are affecting a lot of ecosystem. Also,
  human activity is changing the climate and the
  seasons.
• I think humans should be more aware and
  responsible of their actions.
