The lowest layer of the Earth's atmosphere is the:

Explanation:
Weather and the air we breathe all come from the lowest layer of the atmosphere. This layer is the troposphere. It starts at Earth's surface and reaches up to about 8 to 15 kilometers (roughly 5 to 9 miles), with the height varying by latitude and season. In this region, temperature generally drops as you rise, which helps form clouds and drives the weather we experience—rain, snow, and winds. Most of the atmosphere’s water vapor is here, so storms and weather are concentrated in this layer. Above it lies the stratosphere, where temperature behavior changes and weather phenomena aren’t driven by the same rising-and-sinking air, marking the transition to higher layers.
