Does the rainforest flood?
Seasonal flooding is characteristic of many tropical rivers, although few compare to the so-called igapo (swamp forest) and varzea (flooded forest) of the Amazon River Basin, where large tracts of rainforest are inundated to depths of 40 feet during seasonal flooding.
Why is most of the soil in the rain forest not rich?
In the rainforest, most of the carbon and essential nutrients are locked up in living vegetation, dead wood, and decaying leaves. As organic material decays, it is recycled so quickly that few nutrients ever reach the soil, leaving it nearly sterile.
How do floods affect the rainforest?
Floods can destroy rainforests by disrupting the carbon cycle. Rainforest trees store carbon dioxide in their roots, stems, branches and leaves. Destroying the rainforest causes carbon dioxide to be released, which makes the green house effect even worse.
How does drought affect the rainforest?
Droughts can affect tree productivity, with loss of leaves and reduced canopy cover affecting nutrient cycling, and the amount of sunlight reaching forest floors. ... Under a changing climate, droughts that cause tree mortality may affect forest succession, with drier adapted species replacing wetter adapted species.
How often does the Amazon flood the area around it?
Analyzing more than 100 years of records measuring Amazon River levels in the port of Manaus in Brazil, they found extreme floods that occurred roughly once every 20 years in the first part of last century are now happening about every four years.
How is climate change affecting the rainforests?
Changing climate leads to forest degradation. Once sufficiently degraded, the forest will lose its ability to generate its own rainfall, thereby preventing the rainforest ecosystem from being able to exist at all. Instead of leafy forests teeming with wildlife, the Amazon would be a desolate expanse of shrublands.
What does the term global warming mean?
Global warming is the long-term heating of Earth's climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth's atmosphere.

Why do we need to protect the rainforest?
PRESERVING THE RAINFORESTS We need the rain forests to produce oxygen and clean the atmosphere to help us breathe. We also know that the earth's climate can be affected, as well as the water cycle. Rainforests also provide us with many valuable medicinal plants, and may be a source of a cure from some deadly diseases.
What is unique about the African rainforest?

Do trees have a gender?
Lots of trees are hermaphroditic — that is, their flowers contain both male and female reproductive parts. Other species have male trees and female trees, which you can tell apart by looking at their flowers: The male reproductive parts are the pollen-laden stamen; the female parts their egg-holding pistils.
Do trees cry when cut down?
Plants feel pain too! Researchers find an ultrasonic 'scream' is emitted when stems are cut or if species are not watered enough. A team of scientists at Tel Aviv University have discovered that some plants emit a high frequency distress sound when they undergo environmental stress.
