It fills the pores and fractures in underground materials such as sand, gravel, and other rock, much the same way that water fills a sponge. It's widely believed, for example, that groundwater flows like an underground river: Though there are a handful of places with large underground gaps where water can flow rapidly, these are very rare.Groundwater does move, however, and it %%EOF 0 %PDF-1.6 %���� HL HH�ܭ@Bx�`���W�D�A �������d2#5���� �{ A Groundwater is water that exists underground in saturated zones beneath the land surface.
