Yes, but run-offs (like from oceans and rivers) help too.
Answer:
Ultimately all water is from precipitation but it can reach the groundwater through several routes.
First off groundwater systems have recharge areas (where the water enters) and discharge areas (where the water comes out). Generally the recharge areas are higher than the discharge areas. This is fortunate as water from the sea (the lowest level of water) returning to the groundwater would make it salty and unfit for agriculture or drinking.
Recharge areas can be:
* Where the rain or snow falls on porous ground * The bottoms of lakes or rivers * The base of glaciers Groundwater can also be perched (essentially in a pocket of impervious soil or rock where the water is essentially trapped) or in an aquider which has a very low permeability (the flow is very slow). In some areas this water may have been there for several thousand years and laid down in the last glaciation (ice age).

What is the source of most groundwater?
Precipitation
Main source of groundwater?
precipitation seeping through pores and cracks in the ground the main source of groundwater is rain, and melted snow soak
What is the source of groundwater?
precipitation - rain, snow, ice, sleet, hail
Which is not a major source of groundwater pollution?
Desalination plants are not a major source of groundwater pollution. Groundwater pollution is typically caused by activities such as industrial discharges, agriculture runoff, and leaks from underground storage tanks.
What is precipitation stored between rocks called?
The precipitation stored between rocks is called groundwater. Groundwater is a crucial source of water that is stored beneath the Earth's surface and can be accessed through wells or natural springs.
How are groundwater and precipitation similar?
Groundwater is similar to precipitation is because they are both WATER. *troll face*
Is groundwater powered by gravity?
Groundwater is primarily replenished by precipitation infiltrating into the ground. Gravity does play a role in how groundwater moves through the subsurface, as it causes the water to flow downward due to the force of gravity, but it is not the primary power source for groundwater.
What is precipitation that is stored within rocks?
Groundwater.
What is major source of water on earth?
The major source of water on Earth is the oceans, which hold about 97% of the planet's water. Other sources include rivers, lakes, glaciers, and groundwater.
What is it called when groundwater isn't replaced by rainfall?
Precipitation.
What are the three major uses for groundwater?
The three major uses for groundwater are drinking water supply, irrigation for agriculture, and industrial processes. Groundwater is a vital resource that serves as a primary source of water for many communities and plays a crucial role in sustaining various economic activities.
Precipitation that sinks into the ground is called?
Precipitation that sinks into the ground is called Groundwater.
