2. How is the troposphere important for us?
Answers
Answer:
MEMPHIS, TN (WMC) -The troposphere is the lowest layer of Earth's atmosphere and the site of all-weather on Earth. ... Water vapor it important as it will absorb solar energy and thermal radiation from the surface of Earth, thus regulating the air temperature.

Answer:
Whole life on earth depends on it.
Explanation:
The troposphere is the lowest layer of Earth's atmosphere, containing about 80% of the total mass of the atmosphere. Most types of clouds are found in the troposphere, and almost all weather occurs within this layer. The troposphere extends from the earth's surface upward to about 10 km above sea level. The height of the top of the troposphere varies with latitude; it is lowest over the poles and highest at the equator and by season - it is lower in winter and higher in summer. It can be as high as 20 km near the equator, and as low as 7 km over the poles in winter.
By volume, atmospheric air contains about 21% oxygen and since about 80% of the mass of the atmosphere is in the troposphere, this is where the maximum oxygen content is. As the altitude increases, there is less oxygen.
Air pressure and the density of the air also decrease with altitude. As we go up, the pressure and density decreases. The standard atmospheric pressure at sea level on the Earth is 1013.25 millibars, ideal for life on earth.
Air is warmest at the bottom of the troposphere near ground level. Air gets colder as one rises through the troposphere. Consequently, it holds all the water vapour in the atmosphere. This regulates the temperature on the surface of the Earth, and regulates the weather. The average temperature of the Earth is a very comfortable 16°C.
The Earth's water cycle starts with the troposphere. This process begins when the sun pulls water into the atmosphere through evaporation. Water then cools and condenses, forming clouds. Clouds store water particles, which release in the form of rain.
As you can see, life on earth depends on the troposphere for (1) oxygen, (2) water cycle (3) warmth, (4) ideal air pressure - making Earth a heaven.
