Groundwater can be either saltwater or freshwater, depending on the location. In coastal areas, groundwater can be saltwater due to seawater intrusion. Inland areas typically have freshwater groundwater sources.
Fresh water and salt water form layers due to differences in density. Salt water is denser than fresh water, so when they come into contact, the salt water sinks beneath the fresh water, creating distinct layers. This process is known as stratification.
Piping ocean water into the ground to refill an aquifer may not be feasible due to the high salt content of ocean water. The salt would contaminate the aquifer and make the water unusable for most purposes. Other methods, such as desalination or capturing rainwater, may be more suitable for replenishing aquifers.
Because fresh water comes from rain water, and the moisture in the clouds that form rain is salt-free. If salt water evaporates, the salt stays behind on the ground. But it is possible for a 'fresh water' late to be salty even though it is a long distance from the ocean, if that lake started to dissolve underground deposits of salt. There are some lakes that were made with rainwater that are located over salty ground and they are saltwater lakes. But most lakes are fresh water. I am amazed that the Great Lakes in the northern U.S.A. aren't salty, because it's hard to believe that all those tens of thousands of square miles of ground underneath them doesn't have a similar concentration of salt than the ground underneath the world's oceans. But I suppose if only a couple places on Earth had salt deposits under the oceans, that would be enough for the salt to dissolve and spread worldwide.
No, rivers typically have fresh water, not salt water. Salt water is found in oceans and seas.
Most of Earth's fresh water falls to the ground as rain.
buy the pump and the salt.
groundwater can be fresh, or can have various salts and/or minerals dissolved in it
Fresh and salt water are very different for one key reason, fresh water doesn't contain salt and salt water obviously does. There are different flora and fauna in fresh and salt water for this reason.
on fresh salt water
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.
salt water
Salt water is basically just fresh water with salt mixed in.
Salt water is basically just fresh water with salt mixed in.
Salt water contain salt, fresh water is practically pure.
Peru has both Fresh and Salt water. Salt Water in the ocean and Fresh in lakes, streams, and on the mountains.
Salt water has salt water in it and is bad for you, fresh water has no salt water in it and is good for you.
There are both salt water and fresh water crocs.
