Too many greenhouse gasses in the atmosphere may block heat from escaping into space and trap too much heat next to the Earth’s surface causing: . * another ice age
global warming
earthquakes
volcanoes

global warming.

because these gases, react with the ozone gas in the ozone, hence fading away the ozone layer.

This allows direct sun rays to fall on to Earth's surface hence warming up called global warming

they should be similar or the same

no. dot product   =0 when vecs at right angles
