I just woke up and look around to find my tooth brush but realized, I'm not in my house! I start to panic so I run outside to find everything looks different. So I start to explore to see if I can figure out where I am, but as I walk I start to think maybe I'm in the past. I start to ask where I am but my only answer was the new world. That's when I realized I'm in the 1500's. SO i go to the stores to see what they have and I see a some plain leather boots, I look in my pocket and i have a few dollars so i pay for the boots and head back to my house. When I open the door there was portal and I fell in. When i woke up again i was back in my room from the present, and i still have the leather boots.
The ultimate source of energy that lifts and transports the atmospheric water (vapor and cloud) to its highest elevations is solar energy. It is the sun that gives enough energy to water for its evaporation.
