A sudden shaking or trembling of the Earth's surface caused by the release of energy from within the Earth's crust.

The outermost layer of the Earth, composed of solid rock.

A large wave caused by an earthquake or underwater landslide.

The immense damage caused by an earthquake can include destruction of buildings, bridges, and dams.

Earthquakes can trigger landslides, which occur when masses of rock and soil move downslope.

Earthquakes can cause floods by disrupting rivers and dams, leading to water overflowing.

A large earthquake in a coastal area can trigger a tsunami, causing massive devastation to nearby shores.

Earthquakes can occur all over the world, but major earthquakes are less frequent.

A sudden discharge of static electricity in the atmosphere, often seen as a bright flash of light and heard as a loud crackle or boom.

The accumulation of electric charges in clouds, leading to the discharge of lightning.

An ancient material known for its ability to attract light objects after being rubbed with fur, demonstrating the principles of static electricity.

The ancient Greek philosopher Thales of Miletus, known for his contributions to understanding static electricity through experiments with amber.

American scientist Benjamin Franklin who famously demonstrated the link between lightning and static electricity through his kite experiment.

The process of gradually understanding a natural phenomenon through observation, experimentation, and scientific inquiry.

Actions taken to minimize the risk of harm from lightning strikes, such as seeking safe shelter during thunderstorms.

The study of electric charges, their properties, and their interactions, which helps explain natural phenomena like lightning.

The point on the Earth's surface directly above where an earthquake originates.

Vibrations that travel through the Earth's layers caused by earthquakes.

A device that records ground motion and provides information about earthquakes.

The magnitude of an earthquake, measured on a logarithmic scale.

Buildings designed to withstand earthquake tremors.

An organization specializing in earthquake-resistant building techniques.

The point inside the Earth where an earthquake originates.

The shaking or trembling of the Earth's surface caused by the release of energy.

The outermost layer of Earth, made up of solid rocks.

Large pieces of the Earth's crust that move slowly over time.

A type of electrical charge that is found on objects that have lost electrons. Usually represented by a + sign.

A type of electrical charge that is found on objects that have gained electrons. Usually represented by a - sign.

A device that is used to detect the presence of static charges.

The flow of electrical charges through a material.

The transfer of charge from a positively charged object to the earth.

The sound produced by the rapid expansion of air heated by a lightning strike.

A severe weather condition characterized by lightning, thunder, heavy rain, and strong winds.

A conductive rod installed on a building to protect it from lightning strikes.

Like charges repel each other, while opposite charges attract. So, the statement is false.

A charged glass rod attracts a charged plastic straw because they have opposite charges, resulting in an attractive force. So, the statement is true.

A lightning conductor protects buildings from lightning by providing a safe path for the electric charge to flow down to the ground.

While scientists can predict areas prone to earthquakes, predicting the exact time and magnitude is still challenging. So, the statement is false.

The crackling sound occurs due to static electricity. As the sweater is removed, friction builds up static charge on its surface. When the charge becomes strong enough, it discharges through the air with a crackling sound.

Our hands are good conductors of electricity. When a charged body is touched, the charge easily flows from the body to the hand, discharging it.

The Richter scale is used to measure the magnitude (destructive energy released) of earthquakes. An earthquake measuring 3 on the Richter scale is very small, barely noticeable by humans and unlikely to cause much damage.

To protect from lightning, stay indoors, avoid open fields and tall objects, and use a lightning conductor if available.
