The continental plate is less dense that the oceanic plate and so sinks underneath the oceanic plate. The oceanic plate holds water and so when the continental plate sinks underneath it, the water from the oceanic plate covers the continental plate.
The correct answer is - Greenhouse gas emissions.
The Kyoto protocol was an international convention is which the focus was the reduction of the emissions of the Greenhouse gases. Most of the countries that participated agreed to reduce the Greenhouse gas emissions, and indeed some have make big steps forward in that department, but the problem is that the two biggest emitters of these gases do not commit to it.
The United States and China are the two biggest emitters of Greenhouse gases, but because they do not want to risk anything with their economies, they do not commit to the agreement. Because of this, the Greenhouse gas emissions are still way above of what they should be, and it doesn't seem that that will change any time soon unfortunately.
1. The western and Eastern cities developed at a different period. Eastern cities developed in the 1700s and 1800s while the western cities developed in 1900s, which cause some difference in culture.
2. The next one would be the economic difference between the two. Since western cities are developed during the peak of the industrial revolution, the western cities tend to have stronger economic power compared to the eastern cities.
3. The next one would be the structure. To cater the industrialized worker, western cities tend to have more single-family homes rather than lawns and a center of internet media and technology. The eastern cities, on the other hand, consist of shared housings and mixed neighborhood and would often used for factories due to its wide area.
