Which of the following statement is not correct? I. Laterite soil is useful for growing tea and coffee. II. Laterite soils are formed in areas of high temperature and heavy rainfall.
Neither I nor II
Understanding Laterite Soil Characteristics and Formation
Laterite soil is a specific type of soil found in regions that experience high temperatures and heavy rainfall. These conditions lead to a process called leaching, where heavy rainfall washes away the soluble minerals and silica, leaving behind iron and aluminum compounds. This process gives laterite soil its distinctive reddish color.
Formation of Laterite Soil
Let's examine the statements given in the question:
Statement II: Laterite soils are formed in areas of high temperature and heavy rainfall.
This statement accurately describes the conditions under which laterite soil develops. The intense heat promotes the decomposition of organic matter, while the heavy rain causes leaching of nutrients. Therefore, Statement II is correct.
Crops Suitable for Laterite Soil
Now let's look at the other statement:
Statement I: Laterite soil is useful for growing tea and coffee.
While laterite soil is generally poor in nutrients due to leaching, it is acidic and supports the growth of certain crops, particularly those that thrive in acidic conditions. Crops like tea, coffee, cashew nuts, and tapioca are known to grow well in laterite soil, often with the help of appropriate fertilizers. Therefore, Statement I is also correct.
Conclusion: Which Statement is Not Correct?
The question asks which of the given statements is *not* correct. Based on our analysis:
- Statement I is correct (Laterite soil is useful for growing tea and coffee).
- Statement II is correct (Laterite soils are formed in areas of high temperature and heavy rainfall).
Since both statements are correct, neither of them is incorrect. Therefore, the statement that is not correct is "Neither I nor II".
This means the correct answer corresponds to the option stating that neither statement I nor statement II is incorrect.
Important Questions from Biogeography
Alluvial soils vary in nature from sandy loam to clay. They are generally
The vegetation of savannah consists of grassland with scattered small trees, but extensive areas have no trees. The forest development in such areas is generally kept in check by one or more or a combination of some conditions. Which of the following are such conditions?
1. Burrowing animals and termites
2. Fire
3. Grazing herbivores
4. Seasonal rainfall
5. Soil properties
Select the correct answer using the code given below.
“Leaf litter decomposes faster than in any other biome and as a result the soil surface is often almost bare. Apart from trees, the vegetation is largely composed of plant forms that reach up into the canopy vicariously, by climbing the trees or growing as epiphytes, rooted on the upper branches of trees.” This is the most likely description of
Black soil is also known as 'Black _____ Soil'.
Which of the following statement is correct?
I. Khadar soil is more fertile than Bhangar soil.
II. Laterite soils are the result of excessive leaching from heavy rainfall.
