What is compaction in geology?

Back

Compaction is the process where particles are squeezed together under pressure, reducing the space between them.

Front

What is cementation?

Back

Cementation is the process in which dissolved minerals crystallize and glue sediment together, forming solid rock.

What materials can a magnet move?

Back

A magnet can move ferromagnetic materials like steel and iron, but it cannot move non-magnetic materials like wood.

Front

What is reflection in terms of light?

Back

Reflection is when light bounces off a surface, such as water, changing its direction.

Front

What is refraction in terms of light?

Back

Refraction is the bending of light as it passes from one medium to another, like from air to water.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breaking down of rocks and minerals, while erosion is the movement of those materials from one place to another.

Front

What is an electric circuit?

Back

An electric circuit is a closed loop that allows electric current to flow, typically consisting of a power source, conductors, and a load.

Front

What is the role of a switch in a circuit?

Back

A switch controls the flow of electricity in a circuit, allowing it to be turned on or off.

Front

What is the principle of conductivity?

Back

Conductivity is the ability of a material to conduct electric current, with metals being good conductors.
