17. TBQ - Weathering

Natural factors such as wind, rain, flowing water, and temperature changes help in the formation of soil from rocks through the process of condensationrustingweatheringcombustion. This is a chemical changephysical changebiological changenuclear change because the colour of the rocks changes permanently.the rocks melt into liquid.only the size and shape of the rocks changethe rocks dissolve completely into water., and a completely new metal is formed.no new substance is formednew chemicals are produced.new gases are released.. Therefore, the the rocks become pure iron.chemical composition of the rocks remains the samethe rocks are converted into carbon dioxide.the chemical composition changes completely. even after they break down into smaller particles to form soil.
