B7- Global Warming Flashcards
What is global warming?
The gradual increase in Earth’s temperature due to rising levels of greenhouse gases.
Which gases are primarily responsible for trapping energy from the Sun?
- Carbon dioxide (CO2)
- Methane
What role do greenhouse gases play in Earth’s temperature balance?
They act like an insulating layer, trapping energy that would normally be radiated out into space.
What would happen to Earth’s temperature at night without greenhouse gases?
It would drop significantly as there would be nothing to retain heat.
How does global warming relate to climate change?
Global warming is a type of climate change that causes other types of changes, such as altering rainfall patterns.
What are some potential consequences of global warming?
- Rising sea levels due to expanding seawater and melting ice
- Changes in distribution of wild animal and plant species
- Altered migration patterns for certain species
- Reduced biodiversity and potential extinctions
Fill in the blank: The increase in global temperatures can lead to _______ of habitats.
flooding
True or False: Global warming only affects temperatures and has no impact on rainfall patterns.
False
What effect does higher temperatures have on seawater?
It causes seawater to expand.
What might happen to species that require cooler temperatures as climate changes?
They may have smaller ranges and become less widely distributed.
What could happen to bird migration patterns as a result of global warming?
Some birds may migrate further north as northern areas become warmer.
How much has sea level risen over the last 100 years?
It has risen a little bit.
What is the greenhouse effect?
The process by which greenhouse gases trap heat in the Earth’s atmosphere.
Fill in the blank: Global warming is primarily caused by the increasing levels of _______ gases.
greenhouse
