ANSWER:

The Grand Canyon was formed by erosion.

EXPLANATION:

The Grand Canyon is a 'Steep-sided canyon' carved by the 'Colorado river'. The Grand Canyon is '446 km long', '29 km wide' and has a depth of over 1857 meters. The recent studies have showed that the 'Colorado river' and its tributaries ran through the 'area' about '5 to 6' million years ago. Since that time, there is constant erosion by Colorado river. In this way the 'Grand Canyon' was formed by 'erosion'.

So  if  the sum of the enthalpies of the reactants is greater than the products, the  reaction  will be  exothermic.  if  the products side has a larger enthalpy, the  reaction  is  endothermic. you may wonder why  endothermic reactions, which soak up energy or enthalpy from the environment, even happen

There is no map could you put up a picture of the map and i will try to .
