What is the source of almost all ground water?
A. The ocean
B. Human activity
C. Rainwater soaking into the ground
D. Absorption from rivers
My answer is d.
Water that falls as precipitation flows along the surface of the ground. This surface water infiltrates into the ground surface and is held in soil pore spaces and in the fractures of rock formations. Gaining access to groundwater sources therefore requires digging or drilling through the ground and into an aquifer.
so the answer will be b.
Goodness no. C. How can you miss what I posted.
Prisila, be sure to look up the meaning of the word ‘precipitation.’
The correct answer is actually C. Rainwater soaking into the ground.
Groundwater is primarily formed when rainwater infiltrates into the soil and percolates through porous rocks and sediments, eventually accumulating in natural underground reservoirs called aquifers. It's a slow process that involves the movement of water underground through tiny interconnected spaces in rocks and soil, known as pore spaces. Over time, the water fills these pore spaces and forms large underground water supplies known as groundwater.
To arrive at this answer, you can eliminate options A and B. The ocean is not the source of almost all groundwater, although it can be a source of some salty or brackish groundwater in coastal areas. Human activity, option B, can influence groundwater levels and quality, but it is not the primary source of groundwater. Next, you can consider options C and D. While absorption from rivers, option D, can contribute to groundwater replenishment, it is not the most significant source. Instead, it is rainwater that soaks into the ground, option C, that is the primary source of almost all groundwater.
