Question

1. how is the air in the troposphere different from the air in the thermosphere?

Explanation:

• Density: Troposphere has denser air (more gas molecules per unit volume) as it's closer to Earth. Thermosphere has very low - density air.
• Weather Activity: Troposphere is where most weather phenomena (clouds, rain, storms) occur due to convection currents and water vapor. Thermosphere has no significant weather in the traditional sense.
• Temperature Trend: In troposphere, temperature drops with altitude (average lapse rate). In thermosphere, temperature rises with altitude because of absorption of high - energy solar radiation.

Answer:

The air in the troposphere is denser, has more weather activity, and temperature generally decreases with altitude. The air in the thermosphere is less dense, has high - energy particles, and temperature increases with altitude.
