Question

Wch conditions on Earth's surface will allow for the greatest amount of water to seep into the ground?

Answer 1

they are :
1. gentle slope and permeable
2. gentle slope and impermeable
3. the steep slope and permeable
4. the steep slope and impermeable

Answer 2

The conditions on “Earth's surface” will allow for the greatest ‘amount of water’ to seep into the ground are the steep slope and permeability.

Steep slope located on the earth’s surface will allow the water to run through and get collected onto the lowest crust of the surface of the earth, this causes the maximum amount of absorption into the surface.  

In addition, the surface should be covered with a permeable surface that would support water seepage.
