Most rain
forests lie to the equator(赤道), where the climate is often mild and there are long hours of
sunshine. The warmth of the land heats the air above, causing it to rise and
tiny drops of water to fall as rain. The rainfall can reach at least 98 inches
a year. This wet, warm world with plenty of sunlight is perfect for plants to
grow, so the trees grow fast with green leaves all the year round. The trees
themselves also have an effect on the climate. They gather water from the soil
and pass it out into the air through their leaves. The wet air then forms
clouds, which hang over the treetops like smoke. These clouds protect the
forest from the daytime heat and night-time cold of nearby deserts, keeping
temperatures fit for plant growth.
Rain
forests slightly farther away from the equator remain just as warm, but they
have a dry season of three months or more when little rain falls. Tree leaves
fall during this dry season and new leaves grow when the wet season or monsoon(雨季) begins. Thus these areas are known as the
"monsoon forest".
Another
type of rain forest grows on tropical mountains. It is often called the
"cloud forest" because clouds often hang over the trees like fog.
The rain
forest is the ideal place for the growth of many different trees. Most of them
depend on animals to eat their fruits and spread their seeds. When the fruits
are eaten, the seeds inside them go undamaged through animals' stomachs and are
passed out in their droppings. The seeds lying on the forest floor then grow
into new trees.
