Houses in the hilly areas have sloping roof ?give reason?

People of hilly areas build house with sloping roofs because when snow falls on the roof it can slip down easily from the roof. All the houses in hilly areas have sloping roof so that snow will not accumulate on the roof and put excess pressure on it causing damage to the roof.

Explanation:

All the houses in hilly areas have sloping roof so that snow will not accumulate on the roof and put excess pressure on it to cause damage to the roof. In hilly area there is a heavy rain every time and if house has a sloping roof water can easily slip down on the ground.

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.

it would be heredity
