Carbon Dioxide (COâ‚‚)
Carbon Dioxide (COâ‚‚)
A naturally occurring greenhouse gas essential for life on Earth, but too much can lead to global warming.
Greenhouse Gas
Greenhouse Gas
A gas that traps heat energy from the sun in the Earth's atmosphere, causing a warming effect.
Methane
Methane
A greenhouse gas that traps heat more effectively than carbon dioxide, contributing to climate change.

Study Notes
Climate Change
- Carbon dioxide and methane are greenhouse gases
- Without carbon dioxide, Earth would be frozen
- Climate change affects Earth's temperatures, wind, and rainfall
- Carbon dioxide traps heat near Earth's surface
- Increased CO2 leads to more trapped heat
- Impacts of climate change include:
- More extreme weather events (e.g., hurricanes and typhoons)
- Less predictable rainfall
- Rising sea levels
Examples of Climate Change
- Ice age
- Earth cycles between warm and cold periods
- Snowball Earth
- 650 million years ago, Earth was completely covered in ice
- Also known as "slushball Earth"
Asteroids and Earth
- 470 million years ago, two asteroids collided between Mars and Earth
- Collision produced dust, reducing sunlight and heat to Earth's surface
- This resulted in a cooler Earth
- 47 million years ago, an asteroid collided with Earth
- Huge amounts of dust and rock entered the atmosphere
- Reduced sunlight led to less photosynthesis
- Extinction of many species at that time
Asteroids vs Meteoroids
- Asteroids are larger than meteoroids
- Meteoroids that enter the atmosphere become meteors
- Meteoroids that collide with Earth become meteorites
