6. Groundwater:water that soaks into the ground and collects in pores and empty spaces.
7. Permeable:

8. Impermeable:
describes materials that water cannot pass through.
9.Aquifer:
a layer of permeable rock that lets water move freely.
10. Water table:

11. Spring:
forms when water table meets Earth´s surface.
12. Geyser:
is a hot spring that erupts periodically, shooting water and steam into the air.
13. Cave:
underground opening that can form when acidic ground water dissolves limestone.
14. Long-shore current:
current that runs parallel to the shoreline, is caused by waves colliding with the shore at slight angles,and moves tons of loose sediment.
15. Beaches:
are deposits of sediment that are parallel to the shore.
are deposits of sediment that are parallel to the shore.
