Where are tropical rainforests found?
Tropical rainforests are found primarily in South and Central America, West and Central Africa, Indonesia, parts of Southeast Asia, and tropical Australia. The climate in these regions is one of relatively high humidity with no marked seasonal variation. Temperatures remain high, usually about 30 °C (86 °F) during the day and 20 °C (68 °F) at night.
Why are temperate rainforests less dense than other types of rainforests?
Temperate rainforests filled with evergreen and laurel trees are lower and less dense than other kinds of rainforests because the climate is more equable, with a moderate temperature range and well-distributed annual rainfall. temperate rainforest. A temperate rainforest in the Pacific Northwest.
How deep is the soil in the equatorial forest?
Chemical weathering of rock and soil in the equatorial forests is intense, and in rainforests weathering produces soil mantles up to 100 metres (330 feet) deep. Although these soils are rich in aluminum, iron oxides, hydroxides, and kaolinite, other minerals are washed out of the soil by leaching and erosion.
What happens when rain falls on a tropical rainforest?
Rain falling on the forests drips down from the leaves and trickles down tree trunks to the ground, although a great deal of water is lost to leaf transpiration. tropical rainforest. Vegetation profile of a tropical rainforest. Encyclopædia Britannica, Inc.
How tall is the canopy of a rainforest?
The highest plant layer, or tree canopy, extends to heights between 30 and 50 metres. Most of the trees are dicotyledons, with thick leathery leaves and shallow root systems.
What type of soil is iron?
The presence of iron gives the soils a reddish or yellowish colour and develops them into two types of soils—extremely porous tropical red loams, which can be easily tilled, and lateritic soils, which occur in well-marked layers that are rich in different minerals.
What are the topographic features of the rainforest?
Topographical features of the rainforest regions include the mountains, valleys, streams, wetlands, rivers, etc. A thick forest cover is the prominent feature of tropical rainforests, irrespective of the topography (whether it is plain or mountainous). The forest cover doesn’t allow much light to reach the ground.
What are the landforms of the rainforest?
Landforms in Tropical Rainforests. The rainforest biome is marked by the presence of different landforms such as mountains, valleys, rivers, wetlands, etc. These landforms give rise to a complex ecosystem with varied species. Read to know more in detail.
Why is the tropical rainforest important?
A tropical rainforest is a hub of a multitude of ecosystems, which in coherence, facilitate the flourishing and sustenance of various life forms.
What is the driving factor for lush green forests?
The driving factor for the lush green forests is a constant prevalence of high temperatures and high levels of rainfall. This makes the soil immensely fertile, and thus supports an array of green vegetation. The landforms in the tropical rainforests are the most diverse, and this has contributed to the survival of life.
What is a valley in a tropical rainforest?
Valley in Tropical Rainforest. A valley, is also referred to as dale. It is a depression that can take either a ‘U’-shape or ‘V’-shape. Those valleys which provide channels for the flow of rivers are known as ‘vales’. The ‘V’ or ‘U’ shape of valleys change into a flat surface at their bottom.
Where are mountains found?
A mountain is a topographical feature that rises above surrounding areas and has an altitude higher than a hill. South America, Asia, Australia, Africa and Pacific Islands are the regions where mountains ranges can be found in tropical rainforests. Out of the total mountain cover of the world, 22% is found in South America. Barisan mountains in tropical rainforests of Sumatra Island, Indonesia is one popular example. Mountains are formed by the collision of two tectonic plates. Pico da Neblina which is located in the Amazon Rainforest is counted as one of the highest mountains that is found in a rainforest.

What is the biggest rainforest in the world?
Tropical rain forest – the biggest on Earth – covers two-thirds of the Amazon Basin. Much of this lies on the terra firme uplands, but seasonally inundated bottomland rain forest occupies the floodplains in two basic types: the várzea, along so-called whitewater rivers, and the igapó along blackwater and clearwater streams.
What is the Amazon rainforest known for?
The enormous tropical rain forest carpeting the Amazon Basin in north-central South America is famous for its globally outstanding biodiversity and luxuriant suite of indigenous human cultures.
What is the largest drainage basin in the world?
The Amazon Basin. The Amazon Basin is one of several major structural lowlands in South America, separated by up-warped highlands; others are the Orinoco and Chaco-Pampa basins. Sprawling across about 2.7 million square miles, the Amazon Basin is almost as big as the conterminous U.S., and ranks as the largest of the world’s drainage basins.
How far does the Amazon River flow?
The great Amazon River, which flows more than 4,000 miles across the basin to the Atlantic, likely once drained to the Pacific, but the uplift of the Andes shifted its course to make the epic eastward journey.
How long ago was the Andes basin?
The ancient bedrock underlying the basin is mostly covered by thick layers of sedimentary materials, stemming both from the depositions of rivers draining the Andes and surrounding highlands and from a period when the basin lay beneath a shallow sea, some 2.6 to 5.3 million years ago . Topographically, the basin cants extremely subtly to the east.
What is the flood cycle in the Amazon?
The inundation, which generally occurs in waves across the basin between December and May, spreads river sediment far and wide, a process that over time builds the extensive floodplains, or “várzeas,” across which the channels meander. So great is the weight of the annual flood that the South American continent depresses several inches as it spreads and rebounds as it retreats. Terraces, stemming from down-cutting by rivers through the old sea bed, separate these bottomlands from the older basin uplands, called “terra firme,” which lie above the annual floods.
Which landforms are temperate forests?
In the USA, part of the Appalachian Mountains run into an abundance of temperate forests. Around the Mongolian steppes and along the Pacific Coast in Russia, China, and Korea are expanses of temperate forests. A famous park that is a temperate forest is Great Smoky Mountains National Park located in Gatlinburg, Tennessee.
What is the temperature of the biome?
The temperature ranges from -30 degrees Celsius to 30 degrees Celsius, it's average temperature is 10 degrees Celsius. It has cool winters and warm summers, during the winter it doesn't have much of a food supply so the different animal species either hibernate or migrate during that season. It has five different zones: tree stratum, small tree and sapling, shrub, herb, and ground.
Why are temperate forests left?
Fun Facts! - Less than a quarter of the original temperate forests of the world are left due to humans colonizing and taking advantage of this biome. - This biome is constantly changing in many ways such as weather, climate, tree conditions, etc.
