0 to 4 percent
Water vapor makes up approximately 0.25% to 1% of the Earth's atmosphere. It plays a critical role in the Earth's weather and climate systems as a greenhouse gas.
The amount of water vapor in atmospheric gases is highly variable. More water vapor is found at lower altitudes, at 30,000 feet there is virtually no water vapor. There is a maximum of 4% water vapor in the atmosphere at any time.
0 to 4 percent
The word that goes with "water vapor" is "fraction." In the context of the water cycle, "water vapor" refers to the gaseous state of water, while "fraction" can refer to the percentage or part of water vapor present in the atmosphere compared to other gases.
78% nitrogen, 21% oxygen, 1% water vapor, and i forget the rest
Nitrogen. Nitrogen makes up roughly 78% of Earth's air. The other constituents include : * 20.95% oxygen * 0.93% argon * 0.038% carbon dioxideand traces of other gases, and transported water vapor in varying amounts.
Water vapor and carbon dioxide are the main greenhouse gases.
Water vapor typically makes up about 1-4% of the Earth's atmosphere. This amount can vary depending on location, temperature, and other factors.
On average, water vapor makes up about 0.25% of the Earth's atmosphere by mass. However, this percentage can vary depending on temperature and location.
The amount of water vapor in the air varies considerably depending on climate and weather. In a desert water vapor may account for a tiny fraction of a percent of the air. In a tropical rainforest during a storm water vapor may account for as much as 4% of the air.
Nitrogen (78%), Oxygen (21%), and Other (Argon, carbon dioxide, water vapor)(1%)
On average, water vapor makes up about 0.25% (or 2.5 parts per thousand) of Earth's atmosphere. This percentage can vary depending on location, temperature, and weather conditions. Water vapor is a key component of the Earth's greenhouse effect and plays a crucial role in regulating the planet's temperature.
