Explain earthquake, epicenter, richter scale and volcano.
Answers
Answer:
An Earthquake is what happens when two blocks of the earth suddenly slip past one another. ... The location below the earth's surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter. Sometimes an earthquake has foreshocks.
The Epicenter is the point on the earth's surface vertically above the hypocenter (or focus), point in the crust where a seismic rupture begins.
The Richter Scale, also known as the local magnitude (M) scale, assigns a number to quantify the amount of seismic energy released by an earthquake.
A Volcano is an opening in the earth's crust through which lava, volcanic ash, and gases escape. Volcanic eruptions are partly driven by pressure from dissolved gas, much as escaping gases force the cork out of a bottle of champagne. ... As the magma rises, pressure decreases, allowing the gases to form bubbles.
Answer:
1.Earthquake = Earthquake is a Ground shaking And Radiation energy caused by volcanic Or Magnetic Activity on Earth .
2. Volcano = It is a hole in a mountain at the top
through which hot melted Rock ,
Fire Etc. Came out
3. Richter Scale = It is a numerical scale for expressing the magnitude of an earthquake on the basis of seismograph oscillations.
