Recall the different types of Weathering

What is weathering?

• Weathering is the process of creating new rocks.
• Weathering is the breakdown of rocks.

• Weathering refers to the movement of rocks from one place to another.
• Weathering is the formation of clouds in the atmosphere.

Recall the three types of weathering.

• Frost, heat, and pressure weathering
• Mechanical, thermal, and electrical weathering
• Erosion, sedimentation, and compaction
• The three types of weathering are physical, chemical, and biological.

How does Weathering affect the landscape?

• Weathering creates new rocks and minerals.
• Weathering alters the landscape by breaking down rocks, forming soil, and changing landforms.
• Weathering has no impact on the landscape.
• Weathering increases the height of mountains.

What is Physical Weathering?

• Rocks break apart due to natural forces like temperature changes or pressure.

• Rocks dissolve or change composition due to chemical reactions.

• Living things break rocks.

What is an example of freeze-thaw action?

• Water freezes in cracks, expands, and breaks the rock.

• Layers of rock peel due to heating and cooling cycles.

• Acid rain dissolving limestone.

What is Chemical Weathering?

• Chemical weathering is the physical breakdown of rocks by wind and water.
• Chemical weathering involves the transportation of rocks by glaciers.
• Chemical weathering is the breakdown of rocks through chemical reactions.
• Chemical weathering is the process of rocks melting due to high temperatures.

What is an example of biological weathering?

• Tree roots growing into cracks and splitting the rock.

• Burrowing animals like rabbits or moles dig into rock and soil, breaking them apart.

• Microbes produce acids that chemically break down rocks.

What are the primary processes involved in the weathering of rocks?

• Erosion, sedimentation, compaction

• Frost action, chemical reactions, biological activity

• Oxidation, hydration, carbonation

• Weathering, transportation, deposition
