Question

A handful of soil was mixed in water and left in a jar for some time. Different components of soil got segregated and formed layers, as shown in the given figure.
Select the correct option regarding layers $X,Y$ and $Z$.

• A. Soil sample having high amount of $X$ than $Y$ and $Z$ is best suited for maize cultivation
• B. Soil sample having almost same amount of $Y$ and $Z$ and comparatively much less amount of $X$ has highest percolation rate and water absorbing capacity
• C. Soil containing more amount of $Z$ and very little $X$ and $Y$ is prominent in areas where Kangaroo rat and Acacia are commonly found
• D. The space between particles is very large in $X$ however particles are small sized and compactly arranged in $Y$ and $Z$

Answer 1

The correct option is C Soil containing more amount of $Z$ and very little $X$ and $Y$ is prominent in areas where Kangaroo rat and Acacia are commonly found

In given figure, $X$ shows clay, $Y$ is slit and $Z$ is sand. Soil sample having high amount of $X$ has small sized compactly arranged particles, which hold large amount of water and it is not good for growing plants as water logging damage the crops. Soil having more $Y$ and $Z$, than $X$ have poor water absorbing capacity. Soil rich in large sized sand particles $Z$ is found in deserts. Soil $Z$ has large sand particles and space is filled with air.
