predominant? *
O Less than 100 nm
Greater than 300 nm
Between 100-300 nm
O All wavelengths are equally present
At what concentration (in ppm), is nitrogen present in the atmosphere? *​

Answer 1

Answer:

The atmosphere comprises of layers based on temperature. Each layer has a specific composition of gases. These layers are the troposphere, the stratosphere, mesosphere and thermosphere. All these layers are placed to a different level from the earth.

The troposphere is the lowest layer of the Earth's atmosphere. It starts at Earth's surface and goes up to a height of 7 to 20 km above sea level. Most types of clouds are found in this region, and almost all weather occurs within this layer. It holds nearly all of the water vapor in the Earth's atmosphere, regulates temperature and produces weather. Hence option C is correct.
