Because the oceans are at sea level and the rivers are always above sea level, meaning that water flows downhill.

What does runoff include?
Water also reaches the ocean as runoff from the surface. Runoff includes flow from rivers as well as melting snowfields and glaciers.
Running water above earth surface?
surface runoff (also known as overland flow or terrestrial runoff) is the unconfined flow of water over the ground surface, in contrast to channel runoff (or stream flow)
What is surface runoff groundwater?
A runoff is precipitatoin soaks into the ground, precipitation can also run over the ground and flow into streams, rivers, lakes, and eventually the ocean.
That water that moves across Earths surface after rainfall is called what?
runoff
What are some ways that water can flow over Earth's surface?
Runoff
What would happen to the oceans if surface runoff and groundwater flow were reduced for example by the growth of ice sheets during an ice age?
The ocean would become smaller.
What is surface flow?
Surface flow is when water from the rain runs on the surface into the ocean.
What refers to the water on top of the ground that begins to flow away due to gravity?
surface runoff
What are different kinds of runoff?
1. Surface Runoff: It is that portion of rainfall which enters the stream immediately after the rainfall. It occurs. When all losses are satisfied and if rain is still continued, with the rate greater than in filtration rate; at this stage the excess water makes a head over the ground surface (surface detention) which tends to move from one place to another, known as overland flow. As soon as the overland flow joins to the streams, channels or oceans, termed as surface runoff.2. Sub - surface Runoff: That part of rainfall, which first leaches into the soil and moves laterally without joining the water - table to the Streams Rivers or oceans is known as sub - surface runoff. Sometimes sub - surface runoff is also aerated under service ninoff due to reason that it takes very title time to reach the river or channel in comparision to ground water. The sub - surface runoff is usually referred as interflow.3. Base flow: It is delays flow, defined as that part of rainfall which after talling on the ground surface in fill rated into the soil and meets so the water table and flow to the streams oceans etc. The movement of water in this type of runoff is very slow that is why it is also referred as delayed runoff. It takes a long time to join the rivers or oceans. Some times base flow is also known as ground water flow.
What is the difference between surface runoff and through flow?
Throughflow is the tranfer of water through th soil. Surface runoff is the transfer of water where the soil is impermeable so the transfer of water is on top of the soil.
What controls surface runoff by building retaining walls?
The flow of surface run-off can be controlled by building retaining walls called _____.
What would happen to the oceans if surface runoff and groundwater flow did not occur?
the oceans would become smaller
