1.Forests are rich in vegetation. Herbs, shrubs and trees in the forests hold the top most layer firmly by their roots. This does not allow natural forces like wind and water to carry away the top most fertile layer of the soil easily. Hence, forests prevent soil erosion.
2.Concave mirror is used in headlights of vehicles, because when the bulb of headlight is placed at focus of concave mirror, it allows the light to spread out to infinity (longer distances). For the same reason, concave mirror is used in torches also.
