The rivers flow increase.
Rivers of molten rock, also known as lava flows, are streams of molten rock that flow down the sides of a volcano during an eruption. They can vary in speed and volume depending on the type of lava and the slope of the volcano. Lava flows are a fundamental process in volcanic activity and can cause significant destruction to surrounding areas.
Streams(also rivers) come from seas and head into land and tend to make a loop.
Streams of molten lava out of a volcano are called 'lava flows'.
Jet Streams
Known as the water cycle, basically, water is evaporated off the oceans and form clouds. The clouds drop rain on the land, and the rain water flows downwards and into rivers, and returns to the ocean. The water cycle then continues.
Runoff water
runoff
The water that flows in streams and rivers into the ocean and lakes is called runoff or freshwater.
water that flows downhill and into rivers and lakes is
Streams run into larger rivers.
Streams run into larger rivers.
Water flows in rivers and streams due to the force of gravity pulling it downhill. The water follows the path of least resistance, moving from higher elevations to lower elevations, creating the flow that we see in rivers and streams.
Streams and rivers are the result of rain falling to the ground. The water runs downhill and flows towards the sea.
Runoff
A simplified version of the water cycle is: Water is evaporated by sun and wind from the ocean. The evaporated water forms a vapour that creates the clouds. The clouds rain down on the land (and sea). The rain flows into streams, rivers, and back into the sea. Then the evaporation begins all over again - so continuing the water cycle.
Well, groundwater and runoff both land on Earth as precipitation, but groundwater is water that gets trapped underground by seeping through rocks. You capture this water by wells. Runoff is when precipitation flows from (usually) mountains. The water gets into streams, and streams join to form rivers. The rivers would usually lead to the ocean. Most of the runoff gets evaporated when the water reaches the ocean; only a little-bit of the water in rivers and streams flowing down is evaporated then.
I believe that would be called RUNOFF water.
