Q3 LESSON 1 SCIENCE 10 (ATMOSPHERE)

Which layer of the atmosphere does all weather occur?

• exosphere

• troposphere

• mesosphere

• thermosphere

Which layer of the atmosphere helps us by burning up incoming meteors?

• exosphere

• troposphere

• mesosphere

• thermosphere

Which layer of the atmosphere contains the ozone layer?

• troposphere

• thermosphere

• methosphere

• stratosphere

A compound made of three oxygen atoms is called

• acid rain

• smog

• ozone

• carbon dioxide

Which layer of the atmosphere do we live in?

• tropsophere

• stratosphere

• mesosphere

• thermosphere

What is the function of the ozone layer?

• to allow UV rays to get to Earth
• to block UV rays from getting to Earth
• To keep oxygen in
• to allow meteors to get to Earth

Air pressure is ____________________.

• Amount of mass in a given volume of air

• caused by the weight of a column of air pushing down on an area

• how closely packed air molecules are in a given space

Lia lives in the mountains of Colorado. Her aunt came to visit and had difficulty breathing for a few days until she adjusted to the higher altitude. Which explanation best describes the reason for this difficulty?

• Decreased air pressure causes the density of air to increase at higher altitudes.

• Decreased air pressure causes the density of air to decrease at higher altitudes

• Increased air pressure causes the density of air to increase at higher altitudes

• Increased air pressure cause the density of air to decrease at higher altitudes

The thermosphere is the layer of the atmosphere that…..

• Contains the weather

• Protects earth from meteors

• Has the lowest density of air since it is the boundary of space and the atmosphere

The mesosphere is the layer of the atmosphere that

• Absorbs the most energy from the sun

• Protects earth from meteoroids

• Contains ozone which reflects heat from the sun
