Air Pressure & Layers of the Atmosphere

What layer of the atmosphere do we live in?

• Troposphere

• Stratosphere

• Thermosphere

• Mesosphere

Answer explanation

The troposphere is the layer closest to Earth's surface. “Tropos” means change - because the weather is constantly changing in this layer.

In which layer would find a shooting star?

• Troposphere

• Stratosphere

• Exosphere

• Mesosphere

Answer explanation

The exosphere is the layer furthest from Earth's surface. “Exo” means “outer”.

The ozone layer is part of which layer?

• Troposphere

• Stratosphere

• Thermosphere

• Mesosphere

Answer explanation

The ozone layer is part of the stratosphere. It is the 2nd layer from Earth's surface. “Stratus” means "layer".

Airplanes fly in which layer?

• Troposphere

• Stratosphere

• Thermosphere

• Mesosphere

Answer explanation

Airplanes fly in the lower stratosphere. Most commercial jets fly at around 28,000 to 35,000 feet.

The International Space Station orbits in which layer?

• Stratosphere

• Exosphere

• Thermosphere

• Mesosphere

Answer explanation

The ISS orbits Earth in the thermosphere. This is the 4th layer from Earth's surface. "Thermo" means "heat".

What layer is above the stratosphere?

• Stratosphere

• Exosphere

• Thermosphere

• Mesosphere

Answer explanation

The layer above the stratosphere is the mesosphere. Use this mnemonic device to remember the order: The Silly Monkeys Twirled Endlessly.

Clouds are found in this layer.

• Stratosphere

• Troposphere

• Thermosphere

• Mesosphere

Answer explanation

“Tropos” means "change". The troposphere gets its name from weather that is constantly changing.

This layer separates the rest of the atmosphere from outer space.

• Troposphere

• Stratosphere

• Exosphere

• Mesosphere

Answer explanation

The exosphere is the layer furthest from Earth's surface. “Exo” means “outer”.

Where does weather occur?

• Stratosphere

• Troposphere

• Thermosphere
