Where does the water begin?
The water cycle has no starting point. But, we’ll begin in the oceans, since that is where most of Earth’s water exists. The sun, which drives the water cycle, heats water in the oceans. Some of it evaporates as vapor into the air.
How will a droplet of water travel through the water cycle?
Water drops form in clouds, and the drops then return to the ocean or land as precipitation – let’s say this time, it’s snow. The snow will fall to the ground, and eventually melts back into a liquid and runs off into a lake or river, which flows back into the ocean, where it starts the process again.
How do you see water droplets?
The number and size of the droplets depend on the degree to which the atmosphere is oversaturated, and the number and characteristics of tiny particles, called cloud condensation nuclei, on which the water condenses. When enough droplets of at least a few tenths of a micron form, they become visible as a cloud.
Where does the water come from in your house?
As far as where all the water is from that we use in our homes, it is from either a groundwater source, such as a well, or from a surface-water source, such a river, lake, or reservoir.
What happens to water droplets?
When water vapor in the atmosphere loses heat and cools down, condensation happens. As the water vapor cools down and condenses, it attaches to small particles of dust floating in the atmosphere, forming tiny liquid water droplets. Eventually, the drops will become so heavy that they can no longer float in the air.
Where are water droplets found in the air?
In summary, if the warmer air is located outside, the water droplets would be found on the outside/outer surface. Similarly, if the warmer air is located inside, the water droplets would be found on the inside/inner surface. John was driving home one day and felt uncomfortable as the cold air from the aircon vent was blown directly at his face.
How are water droplets formed in the water cycle?
WARMER water vapour from the surrounding air comes into contact with the COOLER surface of the object, LOSES HEAT to it and CONDENSES to form water droplets. I’d like you to pay special attention to the bolded keywords above.
How are water droplets formed in a bus?
This also causes the glass windows of the bus to lose heat to the cooler air in it to decrease in temperature. Thus, the warmer water vapour from the surrounding air will come into contact with the cooler outer surface of the bus’s glass window, lose heat to it and condense to form water droplets.
Where do you see water droplets in the morning?
Water droplets observed on the glass windows of public buses early in the morning when heading to school. Water droplets observed on my spectacles when I step out of an air-conditioned room. Water droplets observed on the bathroom mirror after I have taken a hot shower.
