Atmosphere

What is the correct order of the layers of the atmosphere?

• Troposphere, Thermosphere, Mesosphere, Exosphere, Stratosphere
• Troposphere, Stratosphere, Mesosphere, Thermosphere, Exosphere
• Exosphere, Thermosphere, Mesosphere, Stratosphere, Troposphere
• Thermosphere, Stratosphere, Mesosphere, Troposphere, Exosphere

Why does the troposphere experience the greatest amount of atmospheric pressure compared to the other layers?

• It produces the Ozone layer.
• It has the highest temperatures.
• It contains a high concentration of gas particles.
• It is the region in which weather occurs.

Which layer of the atmosphere is the Ozone located?

• Thermosphere
• Mesopshere
• Stratosphere
• Troposphere

 Which statement correctly describes a difference between the mesosphere and the stratosphere?

• The mesosphere has more active weather than the stratosphere.
• The mesosphere contains fewer air particles than the stratosphere.
• Air pressure is lower in the stratosphere than in the mesosphere.
• Temperatures decrease with altitude only in the stratosphere.

 Which statement correctly describes a difference between the mesosphere and the stratosphere?

• The mesosphere has more active weather than the stratosphere.
• The mesosphere contains fewer air particles than the stratosphere.
• Air pressure is lower in the stratosphere than in the mesosphere.
• Temperatures decrease with altitude only in the stratosphere.

Which statement best explains why the Thermosphere has the least gravitational pull?

• The Thermosphere is closest to the moon and the moon's gravity is pulling on it.
• The Thermosphere is the closest to Earth and the gravity pulls on it the most.
• The Thermosphere has the most particles in it for the moon's gravity to pull down.
• The Thermosphere is furthest away from Earth's gravitational pull.

In the picture, where would the air pressure be the greatest?

• At the beach
• On top of the mountain
• At the bottom of the clouds
• Above Earth's atmosphere

What layer has the Aurora Borealis?

• Troposphere
• Mesosphere
• Thermosphere
• Stratosphere

What does the Ozone layer do?

• It protects us from meteors.
• It protects us from violent solar flares.
• It protects us from the sun's harmful radiation.
• It helps us breathe.

What layer protects us by burning up meteors

• Mesosphere
• Exosphere
• Thermosphere
• Stratosphere
