Erie has 100 000 people, and Pittsburgh has 300 000 - so from the first two Pittsburgh is the bigger one.
Philadelphia has 1.5 million people living in it - it is also the biggest city in Pennsylvania (this is the state where all the cities are) - and this is also the correct answer!
It is not the capital however, as it's Harrisburg.
Option (d) trapping the sun's energy in the atmosphere is the correct answer.
A direct result of having greenhouse gases in the atmosphere is trapping the sun's energy in the atmosphere that causes global warming.
<h3>How are the greenhouse gases responsible for the climate change?</h3>
Greenhouse gases are responsible for global warming because they retain heat that would otherwise escape from the atmosphere, greenhouse gases are to blame for global warming. These gases, as opposed to oxygen and nitrogen, are able to absorb radiation and retain heat.
Earth is kept at a temperature where life can exist because to greenhouse gases. The Earth would be far too cold without greenhouse gases for the majority of life as we know it. On the other hand, if the concentration of these gases is too high, the greenhouse effect will become unmanageable and lead to an unacceptably hot global temperature.
