In which layer of the atmosphere does most weather occur?

Troposphere

Explanation:

The earth's atmosphere is divided into several layers, namely-

(1) Troposphere

(2) Stratosphere

(3) Mesosphere

(4) Thermosphere

The troposphere is the layer that extends up to a height of about 10 km from the ground surface. In this layer. the temperature decreases with altitude. This is the layer in which all the weather phenomenon takes place. The Oxygen gas this available in this layer that is required by all the living organisms to exist on earth. It also regulates the earth's atmospheric temperature.

Thus, the troposphere is one of the most important layer of atmosphere.

c. movement because i took the test and it lets me review my answers

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.
