Temperature and the Weather

What is temperature? According to Oxford dictionary, temperature is the degrees of intensity of heat present in a substance or object, especially as expressed according to a comparative scale and shown by a thermometer or perceived by touch. For example, the degree of internal heat of a person's body, informal a body temperature above the normal, and the degree of excitement or tension in a discussion or confrontation is also kinds of temperature. According to Wikipedia, temperature is a physical property of matter that quantitatively expresses the common notions of hot and cold. Objects of low temperature are cold while various degrees of higher temperatures are referred to as warm or hot. How is the relationship between the weather and the temperature now? As we can see, the weather is not that good as the past now, the weather temperature is getting higher and higher, and some people from other countries could not endure the hot weather as the temperature is too high as usual. According to 1news.com, there was a Korean girl who committed suicide because of the hot weather and also a guy from Spain who killed himself as he could not handle with the hot weather. As we can see that, hot weather could kill a person in no reason. We should not do anything which can hurt the Earth anymore. The Earth is our home; it gives us a beautiful homes while we are hurting it.

The Great Pacific Garbage Patch

The Great Pacific Garbage Patch, also known as the Pacific Trash Vortex, is a massive collection of garbage that was thrown into the Pacific Ocean. The garbage patch was formed by a gyre, which is a large system of ocean current, sweeping garbage and trapping in the middle of the pacific. The contents of the garbage include probably the largest collection of plastics, chemical wastes, and other debris, usually those that cannot be decomposed easily. It is currently the largest collection of garbage in the world. The garbage patch is growing; some even speculate that soon it might reach the size of Texas. It presents as a hazard to marine life. Sea animals may become trapped or poisoned, even the life under water is in jeopardy because most of the garbage eventually travels down to the sea floor, damaging its ecosystem. Boats and submarine equipment that travels through the great garbage patch might not even leave unscathed. It also poses as a threat to local tourism, namely the tourism in Hawaii. Many islands of Hawaii are currently being affected by large amount of trash that was shot out from the gyres, affecting their once beautiful beaches. Some beaches are buried under several foot of trash, while others are riddled with millions of grain like plastics (otherwise known as “plastic sand”) that was proven to be near impossible to clean up. International treaties that prohibit dumping at sea must be enforced to combat this issue. But that alone is not enough to solve this issue. Eventually the wastes have to be cleaned up, and that might prove to be even more challenging. However, since the main source of garbage is from lands, we must first start with managing how we manage garbage locally.

Haiti Earthquake

On Tuesday, January 12, 2010, a 7.0 magnitude earthquake struck Haiti at a depth of 8.1miles. The epicenter was located fifteen miles of Port-Au-Prince. The United States Geological Survey (USGS) says this was the strongest earthquake to hit the area that is now known as Haiti since 1770. According to Wikipedia, an estimated three million people were affected by the quake, the Haitian government reported that an estimated 316,000 people had died, 300,000 had been injured and 1,000,000 made homeless. The government of Haiti also estimated that 250,000 residences and 30,000 commercial buildings had collapsed or were severely damaged. The earthquake caused major damage in Port-Au-Prince, Jacmel and other settlements in the region. The cause of the Haiti earthquake was because of the surface of earth including the crust and the upper mantle which make up the hard rocky part we stand on is broken up into different pieces. These are called tectonic plates and they float on the much thicker denser layer below called the asthenosphere. The asthenosphere acts like a very thick liquid that flows very slowly, As the tectonic plates are floating on the asthenosphere, they move as well. Haiti is very close to a place where two plates are moving past each other, that is why Haiti earthquake happened.

One Of The Smallest Countries In The World

There are few smallest countries in the world. But the one of the smallest countries that I am going to talk about it is Vatican City. Vatican City is located at Rome, Italy. According to Wikipedia, Vatican City has an area of approximately 44 hectares, and there are about 850 Italian and Swiss permanent residents, along with lay workers from Catholic communities around the world. Most of the people in Vatican City speak Italian and Latin. This makes Vatican City the smallest independent state in the world by both area and population. It is also the governmental capital of the Catholic Church. Although Vatican City is a small country but it is one of the most visited countries, because it is in the middle of Rome and packed with some of the most beautiful churches and museums. Vatican City is an independent country, but it is completely surrounded by the city of Rome. The Vatican City is a Catholic sate whose population is virtually 100 percent Roman Catholic. There is a belief in heaven and hell and in just rewards or punishments for one's actions on earth. There is a belief in a supreme triune God, and various saints are honored. The final judgment and resurrection of the dead are tenets of the faith.
