3.Western hemisphere
4.Eastern hemisphere
Answer:
Canada, United States, Brazil, Argentina
Explanation:
The four largest countries by area in the Western Hemisphere are Canada, United States, Brazil, and Argentina. These countries are located in North and South America, with Canada and the United States being in North America, while Brazil and Argentina being in South America. All of these countries are in the top 10 largest countries in the world by area, with Canada being on the second place, the United States on third, Brazil fifth, and Argentina eight. One of the main reasons why these countries are so large is because they are countries of the New World, all being former colonies, where the populations where relatively small, but the European settlers managed to occupy very large areas. Once they gained independence, the boundaries were set in accordance to the colonial boundaries, so instead of having numerous smaller countries divided because of ethnicity, race, or culture, large multiracial, multiethnic, multicultural countries were established.
The answer is "an American Colony".
"The ordinary man knows that [Saudi Arabia] is the largest oil producer in the world, yet at the same time he is suffering from taxes and bad services. Now the people understand the speeches of the ulemas in the mosques--that our country has become an American colony. They act decisively with every action to kick the Americans out of Saudi Arabia. What happened in Riyadh and [Dhahran] when 24 Americans were killed in two bombings is clear evidence of the huge anger of Saudi people against America. The Saudis now know their real enemy is America." - Osama Bin Laden, July 10th, 1996
Answer:
Wetlands are usually defined as the land that is submerged under shallow water, or the soil is saturated with water throughout the year. These inland wetland areas and coastal areas are affected both naturally as well as due to the human activities in different ways such as-
- Due to the increasing rate of water pollution, where the waste particles produced from the industries and factories, and are eventually mixed with the water and polluting it.
- Due to climate change also, these areas are affected.
- Tide also is another factor affecting these areas.
Three of the major harmful impacts of humans on coastal areas are-
- The pollution has increased in the coastal areas as the humans throw the waste materials here and there near to the sea, where these substances are later mixed with the water.
- Due to the setting up of different things such as seawalls, sea-fence, the rate of erosion has considerably increased.
- The marine life also is affected in the coastal areas, because humans often go for fishing in this area.
Three of the major harmful impacts of human on the freshwater ecosystem are-
- The construction of dams directly affects the aquatic species and also degraded the quality of the water.
- Due to the usage of waterways, these marine species are affected.
- A large number of radioactive waste, chemicals, and other waste materials are released from the industrial sectors which are responsible for affecting the freshwater ecosystem.
