Test: Some Natural Phenomena - 2 - UPSC MCQ

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

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

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

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

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

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

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

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.

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.

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

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

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

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

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

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.

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

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