Final answer:
An unconfined aquifer that intersects with the surface of the earth creates streams.
Step-by-step explanation:
An unconfined aquifer that intersects with the surface of the earth creates streams. Groundwater in the aquifer slowly flows through the pores and fissures of sand, gravel, or rocks, and eventually reaches a stream or lake, replenishing the surface water. Streams flow because of the constant inflow of groundwater from the aquifer below.
