Normally greenhouse gases are not dangerous. They keep the planet warm and allow us to live. But in the last 200 years we have been adding much more greenhouse gases than before to the atmosphere. This is making the atmosphere heat up. This warming happens all over the planet - global warming.
We add greenhouse gases by:
Greenhouse gases must have three atoms, so gases like hydrogen (H2) and Oxygen (O2) are not greenhouse gases.
The warmth of the sun and the global winds mix the greenhouse gases all round the world, so there is nowhere that has more, or less of the greenhouse gases.
they get greenhouse gases cos we poo and the methane comes from cows so cowpat is great!
The greenhouse gases contribute to the greenhouse effect. Greenhouse gases are inescapable.
To sequester means to keep away from other things so sequestering greenhouse gases means to contain the gases in a location away from other gases. Greenhouse gases are building up in the atmosphere, so scientists are investigating ways of pumping them underground.
Greenhouse gases can be very hot, so once they get out into the air, the climate gets hotter.
It is dangerous because it can replace the oxygen in your lungs and it is odorless resulting in asphyxia. methane is a harmful gas that if inhaled, it can kill you. :-[
Oxygen is not a greenhouse gas. It deceases the greenhouse gases.
The glass on the greenhouse stops temperature from leaving or entering like the gases do to the earth.The atmospheric gases are called 'greenhouse gases' based on the idea that the gases 'trap' heat like the walls of a greenhouse do
The greenhouse effect warms the gases in the atmosphere.
Anthropogenic means made by humans, so the greenhouse gases caused by man are mostly carbon dioxide and some methane, and some CFCs.
Greenhouse gases are naturally occurring gases but by increasing the concentrations of greenhouse gases in the atmosphere we are contributing to global warming.
