MCQ (Single Correct) +4 −1
English हिन्दी
The word 'soil' has been derived from which language?
'सॉइल' (Soil / मृदा) शब्द की उत्पत्ति किस भाषा से हुई है?
EXPLANATION Earth Crust, Minerals, Rocks, Weathering Processes and Soil Formation

The English word 'soil' originates from the Latin word 'Solum', which literally means 'floor' or 'ground'.
In pedology, the term 'solum' designates the genetically altered upper soil layers (comprising the A, E, and B master horizons) developed by soil-forming factors above the unweathered parent material (C and R layers).

Hence, the word soil is derived from Latin.

'सॉइल' (Soil) शब्द की उत्पत्ति लैटिन भाषा के शब्द 'सोलम' (Solum) से हुई है, जिसका शाब्दिक अर्थ 'फर्श' (Floor) या 'धरातल' (Ground) होता है।
मृदा विज्ञान में $A$ और $B$ संस्तरों को संयुक्त रूप से वास्तविक मृदा यानी 'सोलम' (Solum) कहा जाता है।

अतः सही उत्तर लैटिन (Latin) है।
