2.2. Water Seepage and Structural Concerns

Try these first

1. 1.

   What type of lava is characterized by a smooth surface?

   Hint

   Think of the Hawaiian names!

2. 2.

   Define basalt in a geological context.

   Hint

   It's a rock formed from cooled lava.

3. 3.

   What is 'Aa' lava known for?

   • Smooth surface
   • Rough surface
   • Elevated structures

   Hint

   Think about the texture you might feel if you touched it.

4. 4.

   True or False: Water seepage can enhance the preservation of cave structures.

   • True
   • False

   Hint

   Consider how moisture affects rock strength over time.

5. 5.

   Consider a cave system showing significant 'Aa' lava presence. If heavy rains lead to major water seepage, how would you categorize the crack developments?

   Hint

   Think about the effects of moisture on lava rock.

6. 6.

   If a conservation team has categorized a cave's structural cracks from 1 to 5, what practical steps should they take based on crack severity?

   Hint

   Prioritize based on instability levels.
