Troposphere

Mesosphere

Thermosphere

Stratosphere

Exosphere

Which statement is true about the troposphere?

• This is the coldest region.

• This is where ozone can be found.

• This is the layer where weather occurs.

• This is where meteor burns up as it enters the planet.

This layer is mainly composed of Helium and Hydrogen and the layer that merges to the outer space.

• Ionosphere

• Exosphere

• Mesosphere

• Stratosphere

In the troposphere, as the height increases, the temperature ​ ​ (a)  

• increases
• decreases
• stays the same
• cannot be determined

In the mesosphere, as the height increases, the temperature ​ (a)  

• decreases
• increases
• stays the same
• cannot be determined

Which statement correctly describes why meteors burn up as it enters the mesosphere?

• The meteor burns because its surface is composed of elements that reacts with the air particles in the mesosphere.

• The meteor burns because it has a hot core and it breaks down as it enters the mesosphere.

• The meteor burns because the temperature of the meteor is high as it comes from the universe.

• The meteor burns because of how dense the air particles are that it creates friction as meteors enter the mesosphere causing it to burn.

Which of the following factors affecting air pressure exhibits a directly proportional relationship with changes in pressure?

• Air Pressure and Density

• Air Pressure and Temperature

• Air Pressure and Humidity

• Air Pressure and Altitude

What is the relationship of air pressure and density?

• directly proportional

• indirectly proportional

• cannot be determined

Which graph correctly represents the relationship between temperature and air pressure?

• A

• B

• C

• D

As the humidity ​ (a)   , the air pressure ​decreases.

• increases
• decreases
• cannot be determined
• stays the same
