1.3.1.1. Physical Weathering

Try these first

1. 1.

   What is physical weathering?

   Hint

   Think about what happens when rocks are cracked but not changed in material.

2. 2.

   Name a process that contributes to physical weathering.

   Hint

   Consider what environmental factors can physically affect rocks.

3. 3.

   Which of the following processes is NOT a type of physical weathering?

   • Exfoliation
   • Erosion
   • Oxidation

   Hint

   Remember that oxidation changes the chemical properties.

4. 4.

   True or False: Physical weathering alters the chemical composition of rocks.

   • True
   • False

   Hint

   Think about what physical weathering actually does.

5. 5.

   Evaluate the impact of physical weathering on soil composition in a mountain region subjected to freeze-thaw cycles.

   Hint

   Think about how broken rocks affect soil texture.

6. 6.

   Design an experiment to demonstrate the effects of temperature on physical weathering using different materials.

   Hint

   Consider how you would simulate the freeze-thaw cycle.
