The Chihuahuan Desert
  • The Chihuahuan Desert starts in Mexico around San
    Luis Potosi and goes north into the US between
    two mountain ranges. It reaches across west
    Texas, New Mexico, and southeastern Arizona.
  • Runoff in the northern half flows to the Rio
    Grande then to the Gulf of Mexico. Playas are
    lakes left over from the Ice Ages and other water
    runoff collects in them. There are Salt Flats to
    the west of the Guadalupe Mountains in west
    Texas.
  • The Climate is cold at night (60ºF) and very hot
    (100ºF) in the day.
  • Some animals found are Gila monsters, foxes,
    bats, hawks, desert toads, and rattlesnakes.
  • Some plants found there are the prickly pears,
    yuccas, honey mesquites, grama grasses, creosote
    bushes, and barrel cacti.
  • The Chihuahuan Desert is the largest in the North
    America and covers the same area as does the
    country of Spain (about 200,000 sq. miles).

The Desert Food Chain
  • The bumblebee eats nectar from the flower on a
    cactus.
  • A lizard then eats the bumblebee.
  • A hawk then eats the lizard.

4
The Life Cycle of a Rattlesnake
  • The rattlesnake lays eggs.
  • The eggs hatch and the baby snakes are already
    poisonous.
  • They grow and then shed their old skins.
  • They eat mice, lizards, rabbits, and squirrels.
  • Hawks can eat rattlesnakes.
