One main difference between oceans and rivers is that oceans are made up of salt water while rivers are made up of fresh water. A river follows a course while oceans surround the continents and are very large.
There are some rivers that are known to be handmade. Rivers are fresh water and come from creeks and oceans.
No ocean can dry out as the rivers keep on bringing fresh water to it.
All oceans are salt water, the only bodies of fresh water are lakes, rivers, streams, etc.
organisms in fresh water had to adapt. they first lived in the oceans.
Fresh water is decreasing because factories put their waste into oceans/rivers that are closest near by and then fresh water spoils.
Only 2.5% of Earth's water is considered fresh water (i.e. not in oceans). Most water is in our oceans.
there is salt water which makes up the worlds oceans and there is fresh water that make up certain streams and rivers
It's actually the salty oceans, because the sun evaporates fresh water from the oceans; it forms into clouds; the clouds blow over the land and drop the fresh water as rain. It collects into rivers and lakes and dams and then into our houses. Fresh!
Salt water is water that has salt in it and it is found in oceans. Fresh water does not have salt and is found in rivers and lakes.
England has many rivers but no oceans.
