Sedimentary rocks are types of rocks formed by the accumulation and compaction of mineral and organic particles, often found in layers.

Front

What is condensation in the water cycle?

Back

Condensation is the process where water vapor cools and collects to form droplets, leading to the formation of clouds.

Front

What is an electrical insulator?

Back

An electrical insulator is a material that does not allow electricity to flow through it easily, such as rubber or wood.

Front

Why does light travel in a straight line?

Back

Light travels in a straight line because it moves in a uniform direction unless it encounters an object that reflects or refracts it.

Front

What is mechanical energy?

Back

Mechanical energy is the energy associated with the motion and position of an object, often used to perform work.

Front

What is the water cycle?

Back

The water cycle is the continuous process by which water evaporates, condenses, and precipitates back to the Earth.

Front

What is the role of glaciers in shaping the Earth's surface?

Back

Glaciers shape the Earth's surface through erosion and deposition, creating landforms like valleys and moraines.

Front

What happens to light when it hits a mirror?

Back

When light hits a mirror, it reflects off the surface, changing direction while maintaining its speed.

Front

What is the difference between a conductor and an insulator?

Back

A conductor allows electricity to flow easily (e.g., metals), while an insulator resists the flow of electricity.

Front

What is the process of evaporation?

Back

Evaporation is the process where liquid water turns into water vapor, usually due to heat.
