Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
On Earth, what process generates most of the water vapor?
A
condensation
B
evaporation
C
precipitation
D
transpiration
Explanation: 

Detailed explanation-1: -Studies have revealed that evaporation-the process by which water changes from a liquid to a gas-from oceans, seas, and other bodies of water (lakes, rivers, streams) provides nearly 90% of the moisture in our atmosphere. Most of the remaining 10% found in the atmosphere is released by plants through transpiration.

Detailed explanation-2: -The ocean holds 97% of the total water on the planet; 78% of global precipitation occurs over the ocean, and it is the source of 86% of global evaporation.

Detailed explanation-3: -The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor. Evaporation is a very important part of the water cycle. Heat from the sun, or solar energy, powers the evaporation process. It soaks up moisture from soil in a garden, as well as the biggest oceans and lakes.

Detailed explanation-4: -Evaporation is the process that changes liquid water to gaseous water (water vapor). Water moves from the Earth’s surface to the atmosphere via evaporation.

Detailed explanation-5: -Most of the water vapor in the atmosphere, along with dust and ash particles, are found in the troposphere-explaining why most of Earth’s clouds are located in this layer. Temperatures in the troposphere decrease with altitude. The stratosphere is the next layer up from Earth’s surface.
