Science Review 1st Semester

Front

What is deposition?

Back

Deposition is the process by which sediments, soil, and rocks are added to a landform or land mass. It occurs when the energy of the transporting medium (like water or wind) decreases, causing materials to settle.

Front

What is erosion?

Back

Erosion is the process by which natural forces move weathered rock and soil from one place to another. It can be caused by water, wind, ice, or gravity.

Front

What is weathering?

Back

Weathering is the breaking down of rocks and minerals into smaller pieces by natural processes such as wind, water, and temperature changes.

Front

What is a conductor?

Back

A conductor is a material that allows electricity to flow through it easily. Examples include metals like copper and aluminum.

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity to flow through it easily. Examples include rubber, plastic, and wood.

Front

What happens to a circuit when one light bulb is removed?

Back

If one light bulb is removed from a series circuit, the circuit is broken, and all the lights will go out.

Front

What is the role of glaciers in erosion?

Back

Glaciers can erode the land by scraping and carrying away rocks and soil as they move, reshaping the landscape.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breaking down of rocks, while erosion is the movement of those broken pieces from one location to another.

Front

What is an example of deposition?

Back

An example of deposition is when sand is dropped by wind or water, forming new landforms like sand dunes or deltas.

Front

What is the importance of conductors in electrical circuits?

Back

Conductors are essential in electrical circuits because they allow electricity to flow, enabling devices to function.
