The trees of the equatorial forest have adapted to the high temperatures and intense rainfall in this region. These hilly and mountain regions may also have young soils, and the combination of young soils and erosion can make for soils that are quite thin. ... flowers, are pre-eminently tropical, and are probably more abundant in the mountains of the equatorial zone than in any other region. There are eight natural regions: savannah, forest, desert, tundra, prairie, jungle, equatorial region and Mediterranean region. Natural regions are geographic areas that possess similar attributes or attributes such as relief, climate, vegetation, soils, hydrography and others. So, to answer this question isn't possible. regions, western and central regions are more arid, because of the incoming dry continental air. The equatorial region extends from 0° to 10° in the North as well as South.

However, in a rainforest, there is a continuous supply of leaves, animal droppings and other organic matter which are quickly broken down with the help of decomposers and incorporated into the topsoil. temperate) regions of the planet. Question 2. Equatorial regions are located in a band around the Equator and cover about 6% of the Earth's surface. They are often in lowland areas and have a climate that is hot and wet all year round. Define the term ‘natural region’. The tropics are the region of Earth surrounding the Equator.They are delimited in latitude by the Tropic of Cancer in the Northern Hemisphere at 23°26′11.2″ (or 23.43644°) N and the Tropic of Capricorn in the Southern Hemisphere at 23°26′11.2″ (or 23.43644°) S; these latitudes correspond to the axial tilt of the Earth. The savannas are grasslands that have several months of dryness, followed by a rainy season. Within the tropics, the equatorial highlands have a distinc­tively cooler climate, modified by altitude, such as the Cameron Highlands in Malaysia, the Northern Andes, and the Kenyan Highlands in East Africa. Proceedings of the National Academy of Sciences, 2011. Features Typical features of this climate are all year round, high daily and nightly temperatures as well as heavy rains falling almost every day. Which region of the Earth would have the greater solar exposure during the Vernal equinox? Torrential downpours wash out most of the top soil nutrients [leaching == percolation and draining way of nutrients due to rain water action]. Jungle.

Answer: This area is very diverse. THE study of soils in equatorial or tropical countries has been very backward in comparison with that in temperate regions in spite of the great development of agriculture in the low latitudes. It is located between 5 north to 5 south. Transfer of organic carbon from topsoil horizons to deeper horizons and to the water table is still little documented, in particular in equatorial environments, despite the high primary productivity of the evergreen forest. The major types of the soils have been discussed here: These soils develop in the hot and humid climates of the equatorial region.

Inferences regarding soil moisture measurement in the indicated hot spots require an assumption of local influence. Soil has three times as much carbon as all land vegetation. Equatorial Vegetation (S289: 1878) ... and wherever the soil is sandy and there are no lofty mountain-chains to supply ample irrigation the result is a more or less perfect desert. And where there is a shortage of soils, vegetation is not seen, e.g., in the polar areas. Rainfall is through out the year so there is luxuriant natural vegetation. These regions agree, to first order, with those that satisfy three conditions: 1) a tendency toward large initial soil moisture anomalies, … (b) Areas the Amazon basin in South America; Zaire basin (Congo basin) in Africa; Indonesian Islands, Malaysia and Sri Lanka in Asia.

The year round high temperatures and abundant rainfall in equatorial regions support a luxuriant type of vegetation – Tropical or equatorial rain forests. In contrast, the high rates of soil respiration found in tropical ecosystems are highly sensitive to small changes in temperature, so that despite the less pronounced warming expected in equatorial regions, tropical soils are likely to release relatively large … The equatorial tropical rainforest is found Under the wet-tropical forests, red-yellow laterites … Roughly 10,000 years, if breaking down glacial deposits in the midwest praries ( the same amount of time since the last ice age). in this vein, languages used in. The equatorial rainforest supports the greatest biodiversity (number and types of living organisms in an area) on Earth. In the current Martian climate, ground ice is unstable in the equatorial regions and, if present, would undergo sublimation and diffusive loss to the atmosphere. These soils are called Soil slopes, relief, and soil depth: Steep slopes in mountain and hilly regions causes soils to be eroded quickly by rainfall unless soils are covered by throughout the year by crops or forest.
