The gases act like the glass walls of a greenhouse – hence the name, greenhouse gases. Without this greenhouse effect, temperatures would drop to as low as -18˚C (-0.4˚F); too cold to sustain life on earth. But human activities are changing earth's natural greenhouse effect with...
Greenhouse gases are gases in Earth's atmosphere that trap heat, and without them, the Earth would be too cold to support life. But what if there are too many greenhouse gases? This lesson will explore these gases and the greenhouse effect. ...
1. Definition of Greenhouse Gases (GHGs): Greenhouse gases are gases in the Earth's atmosphere that have the ability to absorb and re-radiate infrared radiation. This process contributes to the greenhouse effect, which leads to global warming. 2. Mechanism of Action: The key characteristic of ...

What are greenhouse gases and how do greenhouse gases affect plant growth?Greenhouse Effect:The greenhouse effect is an effect that warms the earth's surface where the sun vitality arrives at the environment, some of its light reflected back to space and the remaining light is abso...
The greenhouse effect is entirely due to the fact that the atmosphere absorbs and emits infrared energy, combined with a heat source to warm the bottom of the atmosphere (in our case, the Sun) and the cold depths of outer space above the top of the atmosphere. The greenhouse gases (and ...
What are greenhouse gases? As sun rays hit Earth, they generate heat—consider the temperature difference on a sunny day versus a cloudy one. However, when greenhouse gases (GHGs) are released into the Earth’s atmosphere, they can create a layer of insulation that prevents that heat from es...
Here we shall learn what the greenhouse gases are, how it is emitted by human activity and also how to reduce such emissions.They are Carbon dioxide , Methane, Nitrous oxide, Some industrial gases such as hydro fluorocarbons, Per fluorocarbons, Sulphur h
Burning fossil fuels generates greenhouse gas emissions, which are the most significant driver of observed climate change since the mid-20th century. Greenhouse gases refer to various types of gases that trap heat in the atmosphere such as carbon dioxide, methane, nitrous oxide, and...
The definition of a greenhouse gas is at the same time very simple and very complicated for the ordinary man (or woman !) : such a gaz is “just” a gas mixed in the atmosphere thatabsorbs the infrared radiation emitted by the earth’s surface. We are not accustomed to these gases bec...
