Greenhouse gases

This is a concern due to global climate changes in Earth's environment.

• rising sea level

• melting ice caps

• more severe weather events

• all of these answers are correct

The trapping of thermal energy in the atmosphere when solar energy that was absorbed by Earth is re-radiated into the atmosphere is called the _______________ ______________.

• carbon dioxide

• greenhouse effect

• air pollution

• ozone layer

What layer of the atmosphere blocks the sun's harmful ultra violet (UV) rays from Earth?

• troposphere

• mesosphere

• ozone layer

• exosphere

Any changes to the overall climate of the Earth over several years is ___________ _____________.

• greenhouse gasses

• climate change

• carbon dioxide

• nitrous oxide

When we discuss greenhouse gases what is the main one we discuss?

• Methane (CH₄)
• Carbon Dioxide (CO₂)
• Nitrous oxide (N₂O)
• Flourinated gases

The warming of the atmosphere by the trapping of heat being radiated to space is called

• evaporation
• condensation
• the greenhouse effect
• radiation

Consequences of climate change include:

• Stronger hurricanes
• Increased flooding
• Frequent droughts
• All of the above

Why does cutting down trees increase global warming?

• trees soak up carbon dioxide
• trees provide shade which counteracts global warming
• trees absorbs the sun's energy without radiating back into the atmosphere
• trees drain greenhouse gases like methane from soil
