Paragraph on earthquake in 200 words
Answers
Answer:
An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth, resulting from the sudden release of energy in the Earth's lithosphere that creates seismic waves. Earthquakes can range in size from those that are so weak that they cannot be felt to those violent enough to toss people around and destroy whole cities. The seismicity, or seismic activity, of an area is the frequency, type and size of earthquakes experienced over a period of time. The word tremor is also used for non-earthquake seismic rumbling.
At the Earth's surface, earthquakes manifest themselves by shaking and displacing or disrupting the ground. When the epicenter of a large earthquake is located offshore, the seabed may be displaced sufficiently to cause a tsunami. Earthquakes can also trigger landslides, and occasionally volcanic activity.
In its most general sense, the word earthquake is used to describe any seismic event—whether natural or caused by humans—that generates seismic waves. Earthquakes are caused mostly by rupture of geological faults, but also by other events such as volcanic activity, landslides, mine blasts, and nuclear tests. An earthquake's point of initial rupture is called its focus or hypocenter. The epicenter is the point at ground level directly above the hypocenter.
Answer:
Earthquake means the shaking of the Earth’s surface. It's a sudden trembling of the surface of the world. Earthquakes certainly are a terrible natural disaster. Furthermore, Earthquakes can cause huge damage to life and property. Some Earthquakes are weak in nature and doubtless go unnoticed. In contrast, some Earthquakes are major and violent. the foremost Earthquakes are nearly always devastating in nature. Most noteworthy, the occurrence of an Earthquake is sort of unpredictable. this is often what makes them so dangerous.
The Earth’s crust comprises of the slab of rocks of uneven shapes. These slab of rocks are tectonic plates. Furthermore, there's energy stored here. This energy causes tectonic plates to push from one another or towards one another. As time passes, the energy and movement build up pressure between two plates.
Therefore, this enormous pressure causes the line to create. Also, the middle point of this disturbance is that the focus of the Earthquake. Consequently, waves of energy travel from focus to the surface. This leads to shaking of the surface.
This Earthquake is expounded to volcanic activity. Above all, the magnitude of such Earthquakes is weak. These Earthquakes are of two types. the primary type is Volcano-tectonic earthquake. Here tremors occur because of injection or withdrawal of Magma. In contrast, the second type is Long-period earthquake. Here Earthquake occurs thanks to the pressure changes among the Earth’s layers.
These Earthquakes occur within the caverns and mines. Furthermore, these Earthquakes are of weak magnitude. Undergrounds blasts are probably the explanation for collapsing of mines. Above all, this collapsing of mines causes seismic waves. Consequently, these seismic waves cause an Earthquake.
