Even though you are getting closer to the sun as you ascend into the troposphere, why does the temperature drop? the lower atmosphere is heated by the ground
warm air stays below cold air
the troposphere is a stable layer
ozone blocks the sunlight

hope it's the right warm air stays below cold air

Explanation:

warm air stays below cold air:the troposphere is heated from the ground, so temperature decreases with altitude. Because warm air rises and cool air sinks.

the lower atmosphere is heated by the ground:*the troposphere is heated from the ground*

the troposphere is a stable layer:*the troposphere is unstable*

ozone blocks the sunlight:*in the stratosphere, temperature increases with altitude.The stratosphere contains the ozone layer, which protects the planet from the Sun’s harmful UV radiation*

temperatures get warmer — and heatwaves are more common. nothing says summer like warm weather. this rise in temperatures is caused by the tilt of the earth's axis. our planet doesn't sit perfectly straight as it spins — it has a slight lean of approximately 23.5 degrees with respect to the sun, called the axial tilt.
