Obviously, a body of water the size of a stream or river will succumb to the immutable forces of gravitational attraction, inertia, and the other laws of physics, and be forced to flow downhill. There are some rivers that run from south to north (which is opposite of most), and some that seem to run "backwards", but no rivers run uphill. The starting point of all rivers and streams is of a higher elevation than their end point.
Because rivers need to flow down. It wouldn't make sense if a river flowed up a hill.
yes
youthful stream
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.
Small streams flow into rivers and the rivers flow to bigger rivers.
Rivers are not pure freshwater sources of water. As they flow to the ocean, they pick up small amounts of mineral salts. These slightly-salty rivers flow into the ocean, and as this is a continuous flow and there are thousands of rivers, all the salt builds up, causing the oceans to be saturated with salt. Also, because water evaporates and salt does not, the oceans get saltier over time.
If you can find a single one that flows uphill I will send you a picture of some money !
Rivers typically start at higher elevations because gravity causes water to flow downhill. Rainfall or snowmelt at the top of a hill or mountain collects and forms small streams that join together to create a river. This continuous flow downhill allows rivers to carve out paths over time.
The Rio Grande and other rivers dry up before reaching the sea because humans take so much water from them. Some rivers may also dry up naturally, or drain into a salt lake with no ocean connection.
all rivers end up in the ocean/sea
Actually many rivers run north in North America. Water has no sense of direction. If flows downhill by gravity. Most rivers east of the Rocky Mountains do flow in a southerly direction because the elevation is lower to the south and they are flowing toward the Gulf of Mexico. Source: Riverlorian.com
