The Andes have formed as a result of a subduction zone while the Himalayas have formed as a result of a convergent plate boundary.
Abrasion is caused by the effects of wind and sand.
Subtract 2x from both sides then 3 from both sides and then divide both sides by 4
X=3
25,000 = 2.5 x 10^4
250 = 2.5 x 10^2
0.025 = 2.5 x 10^-2
0.00025 = 2.5 x 10^-4 :D
All of the above would be your answer
