Test: Natural Phenomena - CTET & State TET MCQ

Lightening conductor is used to protect the building against lightening. It is placed at the top of building to passes the charge to earth.

Weathering is the breaking down of rocks into small pieces to form soil. It may occur due to heating, cooling and winds.

Benjamin Franklin showed that lightening and sparks from clothes is same phenomenon. In both cases, opposite charge come in contact of each other to create spark.

Electroscope is a device used to detect the presence of charge. It consists of two leaves like structure that expand when charged particle is charged.

The boundaries of earth’s plates where earthquake tends to occurs are called fault zone. Movement of plates occurs in this zone more frequently.

Like charges repel each other and unlike charge attract each other.

Some area where chances of occurring earthquake is more than the others. Those are where earthquake are likely to occur are called seismic zone.

Lightening strike could destroy life and property if falls on building or tree.

The process of transferring a charge from a charged body to the earth is called Earthing.

Lightening conductor is used to protect the building against lightening. It is placed at the top of building to passes the charge to earth.

The outermost layer of earth is called crust. The middle layer is called mantle and innermost layer is called core.

Building can be protected from lightning by using lightning rod at the top of building. Lightening rod is placed at highest point of the building.

Sudden trembling or shaking of the earth due to disturbance deep down its top layer called as the crust.

An earthquake is the sudden shaking of earth due to disturbance in plates of earth. Huge loss of life and property may occur due to earthquake.

Lightening occurs when two oppositely charged clouds come in contact of other that cause electric spark on huge scale.

Tsunami is caused due to disturbance deep down the sea. Lightning will not cause any disturbance for the sea whereas earthquakes, A major nuclear explosion undersea and Volcanic eruption can cause a disturbance in the sea.

The electric charges generated by rubbing two substances are called static charge. Static charge is charge at rest.

If the charges are like charges they repel each other and if the charges are unlike charges they attract each other.

Lightening is caused due to accumulation of opposite charge on two clouds that come in contact of each other.

Earthquake is caused by disturbance in plates of earth deep inside the earth crust. It causes huge loss of life and property.

A tall tree, high building or a high pillar may be dangerous during lightning because there are chances that they can collapse. So we should maintain a certain position in an open field which makes our body the smallest target to be struck.

The power of earthquake is measured in terms of Richter scale. Earthquake of more than 7 on Richter scale is very destructive.

Earthquake, cyclone and lightning are natural phenomenon as it occurs naturally but cooking is a manmade process.

Intensity of earthquake is measured on Richter scale. The earthquake measuring 7 or more on Richter scale can cause severe damage to life and property.

Earthing is the process of transferring charge from charged objet to earth. Earthing of building is done to prevent it from lightening.

Earthquakes are caused by the movement of earth plates in lower layer of earth.

Jammu Kashmir, Gujarat and Rajasthan are Indian state falling in seismic zone. Uttar Pradesh is not likely to be affected by earthquake.

Static charge is charge that is not in motion. Charge stored in battery or cell and rubbing two substances create static charge.

Using a mobile phone during a thunderstorm is safe because it operates wirelessly and is not connected to cables or wires that could conduct lightning. However, using corded devices or interacting with electrical systems like switches can be dangerous due to the risk of lightning-induced electrical surges.

Lightning conductors safely direct the electric charge from lightning into the ground, protecting the building from damage. Other options, like TV antennas or tall trees, can increase the risk instead of reducing it.
