Answer:
Clouds are made of microscopic droplets of water ranging from 1 to 100 microns. Although, a water droplets total size, water's density is still much greater than air, and over time the earth's gravitational pull should cause the water droplet to fall.
Answer:
Option A, Upper areas are cooler than others
Explanation:
The relation between the latitude and climate i.e temperature is inversely proportional.
Regions located at lower latitude are actually located at a distance far away from the equator. An equator receives the highest sunlight thus a region located at a distance far away from the equator receives lower amount of sunlight due to which its temperature is a bit colder as compared to regions lying close to the equator.
Hence, option A is correct
