about 12 hours sunlight, 12
hours darkness.

winter, because deserts are
near the equator.
Wind Speed

on each desert.
• Wind speeds can be
stronger the other biomes
because there is little
vegetation to slow down
the wind.
• Heavy winds can cause sand
drifts (sand dunes) and sand
storms.
Effects on Organisms

adapt.
• Cacti store water in their
stems.
• Many bushes have few
leaves.
• Many different plants have
a large root system to
absorb water.

the desert to be
uninhabitable by many
animals.
