Layers of the Atmosphere Review

What is the mesosphere known for?

• Being the layer where most meteors burn up upon entering Earth's atmosphere.

• Containing the highest concentration of ozone in the atmosphere.

• Being the coldest layer of the atmosphere with temperatures dropping significantly.

• Supporting the majority of weather phenomena on Earth.

What is the greenhouse effect?

• The greenhouse effect is the cooling of Earth's surface due to the reflection of sunlight by clouds.

• The greenhouse effect is the warming of Earth's surface due to the trapping of heat by greenhouse gases in the atmosphere.

• The greenhouse effect is the process of plants absorbing carbon dioxide during photosynthesis.

• The greenhouse effect is the phenomenon where the ozone layer protects Earth from harmful UV radiation.

• Methane (0.0002%) and Ozone (0.000004%)

What does the ozone layer protect living things on Earth from?

• Harmful UV (ultraviolet) radiation

• Excessive heat from the sun

• Air pollution from factories

• Cosmic radiation from space

What is the Ozone Layer made from?

• Oxygen gas (O2)

• Carbon dioxide (CO2)

• Ozone (O3)

• Nitrogen (N2)

What is the atmosphere?

• The atmosphere is the layer of gases that surrounds Earth.

• The atmosphere is a solid layer of minerals beneath the Earth's surface.

• The atmosphere is the water vapor present in the oceans.

• The atmosphere is the layer of ice that covers the polar regions.

Which layer of the atmosphere do we live in?

• Stratosphere

• Mesosphere

• Troposphere

• Thermosphere

What is the exosphere?

• The layer of the atmosphere closest to the Earth's surface.

• The outermost layer of the atmosphere, where the atmosphere thins out into space.

• A region of the atmosphere where weather occurs.

• The layer of the atmosphere that contains the ozone layer.

What is the thermosphere characterized by?

• Very high temperatures and the presence of ionized gases.

• Low temperatures and high pressure.

• Presence of liquid water and low atmospheric density.

• Stable temperatures and absence of gases.

What is the main function of the stratosphere?

• To provide a habitat for birds

• To contain the ozone layer, which absorbs and scatters UV radiation

• To regulate Earth's temperature

• To facilitate weather patterns
