1. The beam emitted travels along a straight path and it is divergent in nature. It has its radius increasing progressively as the distance away from the source of light increases.
2. It would be observed that the region where the bulb is positioned has denser light beam. This gets fainter towards the edges of the beam and away from the bulb.
Light lets plants grow for the animals eat them
temperature lets the animals know when they have to hibernate or come out and hunt

Sometimes called mechanical weathering, physical weathering is the process that breaks rocks apart without changing their chemical composition. These examples illustrate physical weathering:
Swiftly moving water
