ANSWER:
It takes about 1000 years to form a 25 cm thick layer of soil is false.
EXPLANATION:
It is discovered that the formation of 1 inch of top soil takes about 500 to 1000 years.
Different rocks take different amount of time to break into soil particles. The action of wind and water causes the rocks to break and form loose soil particles.
CALCULATION:
we know that, 1 inch = 2.54 cm
Thus, 25 cm = 9.84 inch
Therefore, formation of 25 cm thick layer of soil needs 4900 years to 9800 years approximately.
This is a long process and the right conditions are required by rocks to break down into soil particles.
