They could in theory.
Sometimes streams will run into lakes; usually smaller lakes
A natural flow of water from underground is called a spring. Springs occur where an aquifer is filled to the point that the water overflows onto the land surface. This flow of water can create streams or rivers.
Lava, groundwater, sometimes minerals that have been melted and which flow into crevices. Depends on where and how far underground.
Water can defy the force of gravity and flow uphill. This is possible when a device called a hydraulic ram is used. A wick action such as a rope can cause the water to flow uphill.
water cannot flow uphill
The Nille River flows uphill
what is the source of the streams that flow from the Alps?
They just lead everything they pull to the bottom of the ocean.More Information:Fresh water whirlpools lead water flow underground to re-emerge further down the aquifer as underground tributaries or as running springs. Sometimes they flow to underground streams that may appear as large fresh water springs, some distance out to sea. In the case of dams, an upstream whirlpool is evidence of a low level breach, under or around the dam.
No, water cannot flow uphill in a pipe without the assistance of a pump or other external force.
Momentum. :]
Regions overlying limestone bedrock tend to have fewer visible groundwater sources (such as streams & ponds), since surface water easily drains downward through permeable fractures and fissures in the limestone
Water can flow up hill if there is some sort of machine that is able to pull it. Water does not naturally flow up hill it always flows downstream due to gravity.
