Answer 2

$\Large\bf\red{\underline{\overline{\mid{\orange{Answer:-}}\mid}}}$

=> The troposphere is the lowest layer of Earth's atmosphere. Most of the mass (about 75-80%) of the atmosphere is in the troposphere. Most types of clouds are found in the troposphere, and almost all weather occurs within this layer. The troposphere is by far the wettest layer of the atmosphere; all of the layers above contain very little moisture.
