Question

which of the following explains how water causes rocks to weather ( 1 point)
water can melt rock material
water freezes in the cracks and expands, causing breaks
water reacts with the rock and produces gases
all of the above

Answer 1

water freezes in the cracks and expands, causing breaks

Answer 2

thnx for the help

Answer 3

@josesito http://en.wikipedia.org/wiki/Erosion says water freezes in the cracks and expands, causing breaks.
Also carbondioxide is an acid that solves rock, but that is not exactly one of the answers, so I'd choose from the four answers, the answer two,"water freezes in the cracks and expands, causing breaks" but I am no genius yet.

Answer 4

"water reacts with the rock and produces gases" is also possible
CaCO3 + H2O => Ca(OH)2(in water soluble) + CO2(gas)

Answer 5

And I quickly read the page http://www.wired.com/wiredscience/2012/12/why-do-rocks-melt-volcano/

Might water be able to help melting rock? Discussion is possible.

So Final answer could be "all of the above"

Answer 6
