5 Questions
Which of the following best describes the role of greenhouse gases in trapping heat in the atmosphere?
Greenhouse gases absorb heat and release it slowly.
What is the main reason why greenhouse gases have a significant impact on climate?
Greenhouse gases have strong bonds that trap heat effectively.
How do greenhouse gases in Earth's atmosphere differ from the glass in a greenhouse?
Greenhouse gases trap heat by absorbing it, while glass traps heat by reflecting it.
What is the main characteristic of greenhouse gas molecules that allows them to trap heat?
They have strong bonds that hold the molecules together tightly.
What happens to the heat released by a greenhouse gas molecule?
It is absorbed by other greenhouse gas molecules.
Study Notes
Greenhouse Gases and Heat Trapping
- Greenhouse gases play a crucial role in trapping heat in the atmosphere, creating a thermal blanket that warms the Earth's surface.
Characteristics of Greenhouse Gases
- Greenhouse gases have a significant impact on climate due to their ability to absorb and re-emit infrared radiation, preventing heat from escaping into space.
- Unlike the glass in a greenhouse, which traps heat through physical barriers, greenhouse gases trap heat through their molecular structure.
Molecular Structure of Greenhouse Gases
- Greenhouse gas molecules have a unique characteristic that allows them to trap heat: they have three or more atoms, which enables them to vibrate and rotate when absorbing infrared radiation.
Heat Trapping Process
- When a greenhouse gas molecule releases heat, it is re-emitted in all directions, some of which is directed back towards the Earth's surface, contributing to the warming effect.
