Question

why does lighting strike more frequently in hilly areas?

Answer 1

Electricity always seeks the shortest path to its final destination. On a mountain or tall hill, that is the shorter path than to a level plain. However, even on a level area you do not want to be the tallest object around and you definitely do not want to seek cover uder a tall tree for the same reaon also Because the hills are a shorter path to ground for the lightning discharge.
i hope this will help u
