What is an earthquake in short answer?

An earthquake is the sudden movement or trembling of the Earth’s tectonic plates, that creates the shakes of the ground. This shaking can destroy buildings and break the Earth’s surface.

What Is earthquake short answer Class 5?

Answer: A sudden movement of a part of the Earth’s surface is called earthquake. They are caused by severe shock waves that travel through the solid rocks from the Earth’s crust to the surface.

What Is earthquake short answer Class 8?

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.

What is an earthquake Class 9?

An earthquake is a sudden tremor or movement of the earth’s crust, which usually originates at or below the surface. The outer layer of the earth is solid and is divided into many sections known as plates. These plates, float over the molten magma that flows beneath the earth’s crust.

What is an earthquake class 7?

Answer: Earthquakes are the vibrations inside the Earth’s crust that happen due to seismic disturbances or volcanic eruptions.

What is an earthquake Class 6?

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.

How does earthquake occur Class 5?

Earthquakes are caused due to sudden tectonic movements in the earth’s crust. When the tectonic plates slide over one another, there is a cause of orogeny which results in earthquakes and volcanoes. These disturbances cause vibrations that spread in all directions.

What is earthquake explain in 100 words?

An earthquake is the sudden movement of the Earth’s tectonic plates, resulting in shaking of the ground. This shaking can result in the damage of various structures such as buildings and further breakdown of the Earth’s surface. The study of earthquakes is called seismology.

What is an earthquake Ncert?

An earthquake is, simply put, shaking of the earth’s crust. It is caused due to the energy release, which triggers waves that travel in all directions. The emanation of energy occurs along a fault. A fault is a sharp break in the crustal rocks.

What is an earthquake Class 11?

Earthquake and Seismic Waves. Meaning of Earthquake: Sudden movement or vibration on the earth surface is called earthquake. In other words, sudden release of energy due to tectonic activity is called earthquake.

What is earthquake waves Class 11?

Verified. 125.1k+ views. Hint: The energy and vibration that travels through earth’s layers when an earthquake , volcano or other explosion occurs, is called seismic wave. These waves travel through different layers of earth. As different layers have different densities, these waves get reflected and refracted.

How is earthquake caused Class 7?

Earthquakes are caused by the sudden breaking and movement of the tectonic plates of the earth’s rocky outermost crust. Earthquakes typically occur on plate boundaries. Every earthquake has a focus and an epicentre.

What earthquake causes?

Earthquakes are the result of sudden movement along faults within the Earth. The movement releases stored-up ‘elastic strain’ energy in the form of seismic waves, which propagate through the Earth and cause the ground surface to shake.

What is earthquake and its effect?

The primary effects of earthquakes are ground shaking, ground rupture, landslides, tsunamis, and liquefaction. Fires are probably the single most important secondary effect of earthquakes.

What is earthquake and its types?

There are four different types of earthquakes: tectonic, volcanic, collapse and explosion. A tectonic earthquake is one that occurs when the earth’s crust breaks due to geological forces on rocks and adjoining plates that cause physical and chemical changes.

Who is responsible earthquake?

The earth’s crust consists of various parts of the landmass. They cause changes to the earth’s surface. The plate of the planet responsible for causing earthquakes is the earth’s crust.

How are earthquakes useful?

Earthquakes are useful because of the following reasons:

I)They help in building landforms like rift valley, block mountains and lakes. II)They help in releasing the stored up energy of the earth. III)They tells about the interior of the Earth’s surface. IV)They can make oil and gas extraction more efficient.
