Which pair correctly matches atmosphere layer & feature?

Correct — A. Pair each layer with what it actually holds.

Troposphere: the lowest layer, where almost all weather happens. Correct pair.
Stratosphere: the ozone layer, not meteors.
Mesosphere: where most meteors burn up, not where satellites orbit.
Thermosphere: where the ISS orbits, not the ozone layer.

Troposphere - weather → option (a).

Why the others are wrong

• (b)
  Thermosphere- ozone — Ozone sits in the stratosphere, well below the thermosphere. The thermosphere is where the International Space Station orbits.
• (c)
  Mesosphere - satellites — Meteors burn up in the mesosphere, so nothing can orbit there. Satellites such as the ISS orbit higher, in the thermosphere.
• (d)
  Stratosphere - meteors — Meteors burn up in the mesosphere, the layer above the stratosphere. The stratosphere's feature is the ozone layer.

From the ground up the layers are troposphere, stratosphere, mesosphere, thermosphere, exosphere.

The troposphere holds the water vapour, so clouds, rain and storms happen there. The stratosphere holds the ozone layer that absorbs ultraviolet radiation.

In the mesosphere most meteors burn up. The thermosphere contains the ionosphere, which helps radio transmission.

Key facts

• Troposphere: about 8 km high at the poles and 18 km at the equator, and weather happens in it.
• Stratosphere: up to about 50 km, containing the ozone layer.
• Mesosphere: up to about 80 km, where most meteors burn up.
• Thermosphere: the International Space Station orbits within it.

Common traps

• Placing meteors in the stratosphere: they burn in the mesosphere, one layer higher.
• Putting satellites in the mesosphere: orbits sit in the far thinner air of the thermosphere and above.
