How were Earth's Rainforests formed?

Question

How did the Rainforests form & how long ago were they formed? (Any other info on the rainforests would be great!!!)

Answer 1

Rainforests don't form, they grow. Depending on your definition of "rainforest" they have been around for millions of years. However changes in climatic conditions have enabled forests to evolve and diversify into many different areas and create many different habitats. I think that the first terestial plants were growing about 350 million years ago. There are many different types of rainforest depending on location, water availability, evaporation rates, solar radiation etc. The biggest natural threat to rainforests is fire, other than man.

Answer 2

How Are Rainforests Formed

Answer 3

the places where there are rainforrests are called niches
they usually lie between mountains ,that turn the clouds and brings them back over the same area .as well as being of a contant and favourable temperature ,that can accomodate a lot of species of flora and fauna is included.
where there is a lot of diverse vegetation there are a lot of different animals that live of the plants or each other

A rain forrest is called that because usually it creates its own rain by intensive precipitation

Not always for example by victoria falls in Zambia the spray from the waterfalls feed a rainforrest ,,but the amazon with the Andes backing it has the evaporation going up with dust from the leaves that seed the clouds form the rain when it reaches a cooler hight and rains down again ,the water is just going up and down.

usually forests produce clouds that are taken away by the wind and rain somewhere else ,and so creating a global balance by spreading the water around.

the rain forrests rain on the spot and so get their name

in the days of the dinausaurs the whole planet was covered in a mist and places like England and Antarctica had tropical moments in their history judging by evidence of fosilized plants.

and there must havre been rain forrests all over the place

this planet went through huge climate changes ,which changed flora and fauna species and the face of the lands

but it was not untill man arrived that we began to get the desserts we know today

The Sahara also has evidence of petrified trees,and must have been forrests at one time .not it is like a fire that expands its borders by 7 miles a year.

Lebanon used to be forrests before the Phoenicians made their fleet from the trees as did Spain for their Armada .

Ghengas Kahn burned forrests over huge territories and filled the wells with sand as well as killing everything alive
he was the original Terrorist.

in China today ,irresponsible agriculture with fertilizers ,over pumping surfice aquifiers as well as the deep laying carbon aquifiers .and overuse of tractors that compact ed the ground raising the salt to the surface and overgrazing of lifestock has cause two mayor desserts to grow and merge ,(millions of farmers from over 900 villages are running for their lives from the aproaching duststorms

in the begining of the last century straight plowing and fretilizers turned huge lands in the Us into desserts.

so we are getting more and more desserts and less and less rainforrests

,which is why it is so important to save them ,but overpopulation ,the hunger for land for agriculture to satisfy the hungry people is a stronger force that seems impossible to stop.

the only way we can counter act the diminishing biomass is by planting more of it

we need Flora to supply us with oxigen,absorb poiseness gasses, regulate temperatures (trees absorb heat in the day and release it at night )Desserts are freezing at night and cooking during the day. trees also build and produce the soil with the falling leaves,

SO plant trees where ever you can in the streets gardens plots ,freeholds parks .and if everybody in the world did this we could stop global warming

We need to.

Answer 5

because of more rainfall
