Answer:
The Permeable rocks are rocks such as sandstone, chalk. The Impermeable rocks are rocks such as clay, slate, marble, and granite. Sometimes however, they do vary.
Explanation:
A permeable rock is a rock that has interconnected pores and allow passage of fluids and impermeable rocks are rocks that do not allow fluid to flow.
The PERIMETER of the equator cycle is about 40,000Km. The Greenwich cycle is a bit shorter as the earth is a bit an ellipsoid. About 37,000Km by Google Maps. The distance on the envelope between ANY antipodes (=opposite points on the axis, I won't use "diameter" to avoid confusion) is HALF the perimeter (If you walk the whole perimeter long, you'd get to the same point, of course). The distance through Earth is
D=P/Pi=37,000Km/Pi=about11777Km
