Science Review 1st Semester

Front

What is weathering?

Back

Weathering is the process that breaks down rocks and minerals into smaller pieces through natural forces such as wind, water, and temperature changes.

Front

What are constructive forces?

Back

Constructive forces are natural processes that build up Earth's surface, such as volcanic eruptions and sediment deposition.

Front

What are destructive forces?

Back

Destructive forces are natural processes that break down or remove materials from Earth's surface, such as erosion and weathering.

Front

What is deposition?

Back

Deposition is the process by which sediments are dropped or settled in a new location, often forming features like deltas and sand dunes.

Front

How do sea arches form?

Back

Sea arches are formed by the erosion of rock by water, particularly through wave action that wears away the rock over time.

Front

What happens to a circuit if one lightbulb is removed?

Back

If one lightbulb is removed from a parallel circuit, the other lightbulb will continue to shine.

Front

What is an example of a rapid change to Earth's surface?

Back

Examples of rapid changes include volcanic eruptions, earthquakes, and landslides.

Front

What is the difference between erosion and weathering?

Back

Erosion is the movement of sediments from one place to another, while weathering is the breaking down of rocks without movement.

Front

What is a delta?

Back

A delta is a landform created by the deposition of sediment at the mouth of a river, where it meets a body of water.

Front

What role does water play in weathering?

Back

Water can cause weathering through processes like freeze-thaw cycles, where water seeps into cracks, freezes, and expands, breaking the rock apart.
