Question

What is different between perivous rocks and imperivous rocks?

Answer 1

short Answer:

Pervious rocks are the rocks which allow water to passes between them are known as basically pervious rocks and the rocks which resist or not allow water to pass between them are known as impervious rocks.

Explanation:

The difference between pervious and impervious rocks lies in their ability to percolate water.  

Pervious rocks:

• Rocks are those which allow the passage of water between them.

• Pervious is also known as permeable rocks not porous. Because these have got connected spaces that support percolation of water through the surface.

• Thus, a pervious rock helps comparatively in reducing environmental impact.

Impervious rocks:

• Rocks are those which do not resist the flow of water between them.

• The forces water to run off the drainage or waterways too quickly that can ultimately lead to flooding along with a lot of debris into the following streams.

Answer 2

Answer:

The rocks which are porous and allowed water to go freely is known as pervious rocks and whereas the rock which are not porous and does not allow the water to through due to cracks or defects is known as impervious rocks. Impermeable rocks include shales and unfractured igneous and metamorphic rocks .
