Question

Write down the difference between Troposphere and Thermosphere.

Hint:

Remember the order and key features of atmospheric layers. The Troposphere has weather, while the Thermosphere reflects radio waves.

Answer 1

Troposphere: This is the atmosphere's lowest layer, spanning 0–12 km. It is where most of Earth’s weather happens. The temperature drops as you go higher.

Thermosphere: This layer starts around 80 km and goes up to 500 km. It has ionized particles that bounce back radio waves. The temperature goes up with altitude because of the sun's radiation.
