Answer:
Earthquakes can have disastrous effects on humans and on the environment. An earthquake is the result of trembling, rolling and vibration of the ground triggered by the sudden release of energy that is stored below the surface of the Earth (Ford 2004). A scientific instrument called a seismometer is used by scientists to record, and measure strengthens of earthquakes (McNally 2007). The intensity or the size of an earthquake is measured by a number called the magnitude. Actually, earthquakes occur in everyday and everywhere and as a result, the estimate by scientists for each day is that more than thousands minor earthquakes happen without triggering any physical damage and mostly they are imperceptible. Earthquakes frequently occur in the following countries: China, Indonesia, Pakistan, Iran, United States, Japan, and the Philippines. In these regions there are a lot of earthquakes and also they have numerous volcanoes. There are three main causes of earthquakes: tectonic plate movement, human activities, and volcanic eruptions.
3. Causes
The main cause of earthquakes is tectonic plate movement. The crust of the earth consists of many pieces called tectonic plates. There are plates along the outer layer of the earth which are floating on the molten magma under the crust of the earth. (Ganguly 2008) The convection current in the molten magma drive the plates to move inside the earth. They move continuously until they pass through each other. When the two plates meet together, they start to push and rub each other but they are not moving. After a while, the pressure beneath builds up and keeps on rising. Once they cannot contain the pressure, it will be expelled. This sudden release of energy and the strength of the plates cause the ground shake and the two plates start to break. (Why do earthquake happen? n.d.) For example, on December 26, 2004, an earthquake hit the Sumatra, Indonesia where the Indian and Burmese plates in India Ocean are broken and one plate is moved across the top of the other plate. (Magnitude 9.1-Off the West Coast of Northern Sumatra 2008) The region that breaks on the crust is known as a fault which usually can be seen on the surface of the earth. The point where earthquakes begin and break the plates underground is known as focus and above the focus, on the surface of the earth is called the epicenter. During plate movement, one plate gets submerged into the molten magma and another plate is moved across the top of it. This plate rises up due to the heat of molten magma. The plates keep on moving until they get stuck against each other. Most earthquakes take place on the edges of the plates where one plate is forced further into the earth crust while another plate is moved across the top of the submerged plate.
3.2 Cause 2: Human Activities
Another contributing factor to earthquakes is human activities. There are many human activities that cause an earthquake. Building skyscrapers is a good example that may cause an earthquake. Many engineers and scientists are concerned about the types of buildings in construction. Skyscraper Taipei 101 with the height of 508 meters which is the world’s tallest building. According to the geologist Cheng Horng Ling (2005), from the National Taiwan Normal University, Taipei 101 may cause an earthquake because the 101-storey skyscraper is built the stress on an earthquake faul
Effect 1: Social Impacts
One of the biggest effects of earthquakes is the social impact on survivors. Earthquakes have short term impacts as well as long term impacts. The short term impacts can be seen in the aftermath of earthquakes. We can see thousands of people dying and many corpses.In the cases of long term social impacts, thousands of children became orphans as their parents are killed in the earthquake. Most of the parents are depressed and the town lost a generation because their children were killed in schools that collapsed.
5.3 Effect 3: Economics Impacts
Apart from social and environmental impacts, earthquakes also have negative effects on a nation’s economy. Governments have to be responsible for the damage caused by earthquakes. As we can see, earthquakes cause infrastructures to collapse, reservoirs dams, shops, and hospitals are devastated after an earthquake. (Earthquake n.d.)
Explanation:
mark me the brainliest please
The earth weighs 13,170,000,000,000,000,000,000,000 pounds. You can say this number like this: 13 octillion, 170 septillion. That’s A LOT more than a million, billion, or trillion pounds!
To put things in perspective:
One male African bush elephant weighs 13,000 pounds.
100 elephants would weigh 1,300,000 (one million, 300 thousand) pounds.
One million elephants would weigh 13,000,000,000 (13 trillion) pounds.
One trillion elephants–there are not even this many on earth–would weigh 13,000,000,000,000,000 (13 quintillion) pounds.
