Problem: Given the question: Pollutants also affect the atmosphere through their contribution to global warming. Global warming is an increase in the Earth’s temperature. It is thought to be caused mostly by the increase of greenhouse gases like carbon dioxide. Greenhouse gases can be released by factories that burn fossil fuels. Over the past 20 years, burning fossil fuels has produced about three-quarters of the carbon dioxide from human activity. The rest of the carbon dioxide in the atmosphere is there because of deforestation, or cutting down trees ( Figure below ). Trees absorb carbon dioxide during cellular respiration, so when trees are cut down, they cannot remove carbon dioxide from the air.  Long island was full of people and they used all their natural resources and burned fossil fuels while Snail island protected the environment and had fewer people living there.  Which island contributed less to an increase in greenhouse gasses?
++++++++++++++++++++++++++++++++
The answer is:
Snail


Problem: Given the question: Almost all earthquakes occur at plate boundaries. All types of plate boundaries have earthquakes. Convection within the Earth causes the plates to move. As the plates move, stresses build. When the stresses build too much, the rocks break. The break releases the energy that was stored in the rocks. The sudden release of energy is an earthquake. During an earthquake the rocks usually move several centimeters. Rarely, they may move as much as a few meters. Elastic rebound theory describes how earthquakes occur ( Figure below ).  Tim the seismologist studied data from two cities: Tokyo and Kansas City. Tokyo experienced many more earthquakes than Kansas City.  Which city is located farther from plate boundaries?
++++++++++++++++++++++++++++++++
The answer is:
Kansas City


Problem: Given the question: Gasoline-powered vehicles emit a lot of harmful materials. Nitrogen oxides are formed when atmospheric nitrogen reacts with oxygen at the high temperatures found in a car engine. Carbon monoxide is a by-product of incomplete combustion of hydrocarbons. Evaporated and unused fuel releases volatile hydrocarbons into the atmosphere to help form smog. The presence of a catalytic converter in the exhaust system of the car causes these materials to react and be changed into less harmful products.  Hill town was full of gasoline powered vehicles, while Valley town 50 miles away, banned all gas powered vehicles and allows only electrical vehicles or horse-and-buggies.  Which town had more evaporated and unused fuel?
++++++++++++++++++++++++++++++++
The answer is:

Hill
