Questions & Answers:

1.                   What physical geographic features have aided the development of the United States?
Physical geographic features had affected the development of the United States very much in many different ways. Huge rivers/lakes such as the Mississippi River, the Great Lakes had affected the people very much; these rivers are big help for trading system by ships. Trading system had become one of major successful career of exchanging in the USA - with great amount of resources; they can trade all over the world for valuable objects. Mississippi River and the Great Lakes can help fishing and provide good harbors; fishing helps the USA people who live near the rivers use as their resources. In addition, these rivers can help in agriculture (farming) – they can use them for irrigation system and watering the crops. Not only rivers can aid the United States but also features such as mountains. Mountains such as the Appalachian Mountains that extend to South. The Appalachian Mountain can support trade since it has deep-water harbor, which is helpful especially for sailors. In addition, places with rocky lands, which are mostly located in the Northeast, are very suitable and good for fishing & shipping. These areas also created many large industries such as for textile mills. The Coastal Plain is places with plain – low land that is usually helpful for farming and plantations.

2. What physical geographic features have aided the development of Vietnam?

     Ocean and rivers had become an important contributing factor that help aided the development of the United States. Rivers such as the Mekong River and a huge river at Tran Suan Soan (I do not know the name) had help Vietnam very much. The Mekong River is very important to Vietnamese – they are like the source of life. They help the people in agriculture for farming and transportation. People use this river to water crops and for irrigation systems. In addition, these people usually make rice thanks to help of the river; this make Vietnam owns the largest rice industries. Transportation in this river can happen; people use boats to transport around – carrying resources. Rivers at

Tran Suan Soan Street

are a very helpful “tool” for the people in that society. At the evening, there will be a boat for pupils to transport to their homes. Is more likely to be a “bus” on the river! This river is also use for street sellers – these people bring traditional foods from their homes and use boat to transport to here and sell it.

3. Similarities and Differences.

      The similarities are that both countries used ocean as one of big factors that help aided their countries. They both use rivers and oceans for agriculture and at the end, they make a lot of income from harvesting. Both also had plains, which are low lying land been separate from features. The differences are in the USA there are other features such as mountains that gives big help in trading system, ship harbor and transportation. In addition, these mountain ranges soon help the people to created big manufacturing industries.

Three Facts (PSA)

1.             National Geographic:

Average temperatures have climbed 1.4 degrees Fahrenheit (0.8 degree Celsius) around the world since 1880, much of this in recent decades, according to NASA's Goddard Institute for Space Studies.

The Arctic is feeling the effects the most. Average temperatures in Alaska, western Canada, and eastern Russia have risen at twice the global average, according to the multinational Arctic Climate Impact Assessment report compiled between 2000 and 2004.

Arctic ice is rapidly disappearing, and the region may have its first completely ice-free summer by 2040 or earlier. Polar bears and indigenous cultures are already suffering from the sea-ice loss.

2. Environment National Geographic:

One of the first things scientists learned is that there are several greenhouse gases responsible for warming, and humans emit them in a variety of ways. Most come from the combustion of fossil fuels in cars, factories and electricity production. The gas responsible for the most warming is carbon dioxide, also called CO2. Other contributors include methane released from landfills and agriculture (especially from the digestive systems of grazing animals), nitrous oxide from fertilizers, gases used for refrigeration and industrial processes, and the loss of forests that would otherwise store CO2.

Litter Prevention Around the World
A more grassroots-oriented litter prevention group is Auntie Litter, which started in 1990 in Alabama to help educate students there about the importance of a healthy and clean environment. Today the group works internationally to help students, teachers and parents eliminate litter in their communities.

Only You Can Prevent Litter
Doing your part to keep litter to a minimum is easy, but it takes vigilance. For starters, never let trash escape from your car, and make sure household garbage bins are sealed tightly so animals can’t get at the contents. Always remember to take your garbage with you upon leaving a park or other public space. And if you’re still smoking, isn’t saving the environment a compelling enough reason to finally quit? Also, if that stretch of roadway you drive everyday to work is a haven for litter, offer to clean it up and keep it clean. Many cities and towns welcome “Adopt-A-Mile” sponsors for particularly litter-prone streets and highways, and your employer might even want to get in on the act by paying you for your volunteer time.

What Are Greenhouse Gases?
Many chemical compounds found in the Earth’s atmosphere act as “greenhouse gases.” These gases allow sunlight to enter the atmosphere freely. When sunlight strikes the Earth’s surface, some of it is reflected back towards space as infrared radiation (heat). Greenhouse gases absorb this infrared radiation and trap the heat in the atmosphere. Over time, the amount of energy sent from the sun to the Earth’s surface should be about the same as the amount of energy radiated back into space, leaving the temperature of the Earth’s surface roughly constant.

Many gases exhibit these “greenhouse” properties. Some of them occur in nature (water vapor, carbon dioxide, methane, and nitrous oxide), while others are exclusively human-made (like gases used for aerosols).
