You should probably start by changing the fractions into decimals. then you multiply the decimal of 1 1/4 by the decimal of 3 1/2. Next you multiply the decimal of 1 3/4 by the decimal of 3 1/2. then you find the difference and that's your answer, alternatively you could leave them as fractions, do the same thing and then change it into a decimal.
Hope this helps :)
Answer:
Exfoliation
Step-by-step explanation:
Changes in temperature cause rock to expand (with heat) and contract (with cold). As this happens over and over again, the structure of the rock weakens. Over time, it crumbles.
Rocky desert landscapes are particularly vulnerable to thermal stress. The outer layer of desert rocks undergo repeated stress as the temperature changes from day to night. Eventually, outer layers flake off in thin sheets, a process called exfoliation.
