An earthquake is a sudden shaking (or trembling) of the earth which lasts for a very short time. An earthquake is caused by the violent movements of rocks deep inside the earth’s crust. … Another major earthquake occurred on 8th October 2005 in Uri and Tangdhar towns of North Kashmir.

Which of the following natural phenomena is most destructive in terms of loss of life and property?
Earthquakes are sudden occurences which cannot be predicted like cyclones and the other natural disaters. Hence it is the most dangerous form of disaster to life and property loss.
What are the 4 phenomena?
Four Types of Wave Phenomena There are four phenomena, or behaviors, that can be observed when studying any type of wave. These four phenomena are reflection, refraction, diffraction, and interference. Each of these phenomena are caused by a wave’s interactions with its surrounding environment.
What are the phenomena events?
Phenomena can be defined as events, occurrences or happenings in the world around us. These events can be either spiritual or natural, and can also refer to physical sensations felt by a person. 2. Another definition relates to exceptional occurrences or people.
What are examples of scientific phenomena?
Some examples of explained phenomena include tornadoes and eyebrows. Some unexplained phenomena include yawning, the Moon Illusion, and the placebo effect.
Are Rainbows natural phenomena?
The rainbow is one of the most common natural phenomena we can see, but we are still surprised by this ephemeral meteorological phenomenon. … As we know, the rainbow is caused by reflection, refraction and dispersion of light in drops of water, but the rainbow has more than just seven colors.
Is natural disaster a phenomena?
Phenomena and disasters Phenomena are natural, but the disasters are produced by human action in his environment. For instance, the flooding of a flood plain caused by an overflowing river is a natural phenomenon; the presence of human settlements in the area creates the possibility of a disaster.
Is an eclipse a natural phenomenon?
In a total eclipse, the disk of the Sun is fully obscured by the Moon. … Total solar eclipses are rare at any particular location because totality exists only along a narrow path on the Earth’s surface traced by the Moon’s full shadow or umbra. An eclipse is a natural phenomenon.

What event killed the most humans?
Table ranking “History’s Most Deadly Events”: Influenza pandemic (1918-19) 20-40 million deaths; black death/plague (1348-50), 20-25 million deaths, AIDS pandemic (through 2000) 21.8 million deaths, World War II (1937-45), 15.9 million deaths, and World War I (1914-18) 9.2 million deaths.
What is an earthquake BYJU's?
What is an Earthquake? An earthquake is the shaking of the surface of the earth due to the sudden release of energy in the earth’s crust. As a result, seismic waves (also known as S waves) are created. The seismic activities in an area determine the type and intensity of the earthquake.
How does earthquake occur BYJU's?
Earthquakes are caused by a sudden release of stress along faults in the earth’s crust. … When the stress on the edge overcomes the friction, there is an earthquake. The resulting waves of seismic energy propagate through the ground and over its surface, causing the shaking we perceive as earthquakes.
Is plate tectonic?
A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere. Plate size can vary greatly, from a few hundred to thousands of kilometers across; the Pacific and Antarctic Plates are among the largest.
What happens when amber is rubbed with fur?
Thus, when amber is rubbed with fur, electrons are transferred from the fur to the amber, giving the amber an excess of electrons, and, hence, a negative charge, and the fur a deficit of electrons, and, hence, a positive charge.
How does an electric discharge occur?
Electric discharge refers to the flow of electricity or electric charge through a medium. The medium may be a solid, a liquid or a gas. When two points of different electrical potential make contact in the medium in which they are placed, it causes an electric discharge.
What is a negative charge?
A negative charge is an electrical property of a particle at the subatomic scale. An object is negatively charged if it has an excess of electrons, and is uncharged or positively charged otherwise. Such electrochemical activity plays a vital role in corrosion and its prevention.
What are earthquake causes?
An earthquake is caused by a sudden slip on a fault. … When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth’s crust and cause the shaking that we feel. In California there are two plates – the Pacific Plate and the North American Plate.
What is the scientific name for earthquake?
Seismology (/saɪzˈmɒlədʒi, saɪs-/; from Ancient Greek σεισμός (seismós) meaning “earthquake” and -λογία (-logía) meaning “study of”) is the scientific study of earthquakes and the propagation of elastic waves through the Earth or through other planet-like bodies.
What is earthquake focus?
The focus is the place inside Earth’s crust where an earthquake originates. The point on the Earth’s surface directly above the focus is the epicenter. When energy is released at the focus, seismic waves travel outward from that point in all directions.
What are the 4 types of disaster?
- Geophysical (e.g. Earthquakes, Landslides, Tsunamis and Volcanic Activity)
- Hydrological (e.g. Avalanches and Floods)
- Climatological (e.g. Extreme Temperatures, Drought and Wildfires)
- Meteorological (e.g. Cyclones and Storms/Wave Surges)
