Question

1. water first percolates through the *

soil
concrete
grass
cement

1. then, the water reaches the *

soil
concrete
rocks
grass

1. eventually, the water reaches the ______ beneath *

water table
groundwater
surface
aquifer

Explanation:

• Question 6: Water percolation (the process of water filtering through) occurs through soil. Concrete and cement are impermeable (water - resistant), and grass is above the soil surface.
• Question 7: After percolating through soil, water reaches rocks (as it moves downward through the soil layers towards the groundwater system).
• Question 8: Eventually, water reaches the water table (the upper surface of this underground water). Groundwater is the water itself, the surface is above the soil, and an aquifer is a geological formation that can store and transmit water, but the immediate "beneath" reference here is to the water table.

Answer:

1. soil
2. rocks
3. Water table
