Answer 2

Answer:

(a) Pumice is used as a body scrubber:

• Pumice is used as a body scrubber because it is a natural non-toxic rock with soft abrasive and exfoliating nature.
• As an exfoliating agent, it removes dirt, grimes, dead skin cells, and cleanse the skin pores and smoothens the skin and restores the skin vibrancy and vitality.
• It is a cost-effective, eco-friendly natural body scrubber.  

(b) Fossil fuels are otained from sedimentary rocks:

• Fossil fuels are obtained from sedimentary rocks due to various repeated processes like cementation, compaction, erosion, deposition and weathering which forms the sedimentary rocks over millions of years.
• The dead organic matter also gets sediment along with these rocks and increased compaction leads to increase in temperature which converts these dead organic matters into three main fossil fuels – coal, oil, and natural gas over millions of years.
