Some Natural Phenomena Online Quiz

During a thunderstorm, it is dangerous to use corded telephones or electrical appliances connected to the grid because lightning can travel through wires. Mobile phones are wireless and generally considered safe to use.

An electroscope is a scientific instrument used to detect the presence and magnitude of electric charge on a body. The other terms are not standard scientific devices for this purpose.

When two objects are rubbed together, electrons are transferred from one to the other. This leaves one object with a positive charge and the other with an equal negative charge, resulting in equal and unlike charges.

Seismic waves are the waves of energy caused by the sudden breaking of rock within the earth or an explosion. They are the energy that travels through the earth and is recorded on seismographs.

A tsunami is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake, often triggered by underwater earthquakes.

The Bhuj earthquake, which occurred on January 26, 2001, was a major seismic event in the Kutch district of Gujarat, India.

A lightning rod is a metal rod mounted on top of a building and electrically connected to the ground. Its purpose is to provide a path of least resistance for lightning to travel to the ground, protecting the structure.

There are two types of electric charges: positive and negative. Rubbing objects causes the transfer of electrons, resulting in these two types of charges.

Earthquakes, cyclones, and lightning are natural phenomena. Earthing is a man-made safety procedure involving the connection of electrical equipment to the ground.

A seismograph is an instrument used to detect and record seismic waves caused by earthquakes. The Richter scale is a scale used to measure the magnitude, not the instrument itself.

The Richter scale is a logarithmic scale used to express the magnitude of an earthquake. It quantifies the energy released during the seismic event.

Earthing is the process of transferring the discharge of electrical energy directly to the earth through a low-resistance wire. This prevents damage to equipment and protects people from electric shock.

When a glass rod is rubbed with silk, electrons are transferred from the glass to the silk. This leaves the glass rod with a net positive charge.

Electric sparks on poles occur when wires become loose, causing intermittent contact or arcing between the wires or the pole structure.

Amber is a fossilized tree resin that has been appreciated for its color and natural beauty since Neolithic times. It is not a metal, rubber, or sugar.

Lightning is a massive electrostatic discharge caused by the buildup of electrical charges in clouds. The discharge occurs between clouds or between a cloud and the ground.

An earthquake is a sudden shaking of the ground caused by the movement of tectonic plates or volcanic activity. It is distinct from cyclones (wind) or tsunamis (water waves).

According to the fundamental laws of electrostatics, like charges (both positive or both negative) exert a repulsive force on each other. Opposite charges, conversely, attract one another.

The word electricity is derived from the Greek word for amber, 'elektron'. Thales of Miletus observed that rubbing amber with fur produced static electricity, which can create small sparks.
