Final answer:
The weather forms in the troposphere, the lowest layer of the Earth's atmosphere.
Step-by-step explanation:
The weather forms in the troposphere, which is the lowest layer of the Earth's atmosphere.
The troposphere extends from the Earth's surface up to about 8-15 kilometers (5-9 miles) above the surface. This is where clouds, precipitation, and most of the Earth's weather phenomena occur.
The other layers of the atmosphere, including the stratosphere, thermosphere, and mesosphere, are not directly involved in weather formation.
