cm a year
•
The constant warm air holds a lot of
water vapor causing it to be humid year
round
TEMPERATURE
Normally around 77 degrees
Humid year round
AMOUNT OF LIGHT
The plants near the top (like the canopy area) get more sunlight, they spread their leaves out
to absorb more.
The bottom plants get little to no sunlight, they have adapted to be able to receive nutrients
from just rain water and not sunlight.
AIR QUALITY
•
The air is very polluted in most rain forest
Areas.
Air pollution is damaging critical rainforests. Rainforests act as pollution
sinks -- a process by which greenhouse gas is removed from the
atmosphere -- by soaking up carbon dioxide and neutralizing it.
Greenhouse gases are stored there and are released back into
the atmosphere to further contribute to global warming .
NUTRIENT LEVELS
52% of nutrients are in the vegetation, while only 48% are in the soil.
Weathering and torrential rain have washed most of the nutrients away.
COMMON SPECIES
Rain forest cover only 2% of the earth but house over 2/3 of the species.
