Why are so many streams going dry in places where aggressive extraction of groundwater occurs?
Aggressive extraction of groundwater can deplete underground water sources faster than they can naturally recharge, causing streams to go dry. When groundwater is over-pumped, the equilibrium between surface water and underground water is disrupted, leading to reduced flow in streams that are dependent on groundwater for their water supply. This can have negative impacts on ecosystems, wildlife, and communities that rely on those streams for water resources.

What is the cause and effect of groundwater mining what impact does it have on the water table and lake or stream levels?
Groundwater mining occurs when groundwater extraction exceeds natural recharge rates, leading to a decline in the water table. This can cause reduced flow in lakes and streams connected to the groundwater system, potentially leading to ecosystem degradation and water shortages for human use. Over time, continued groundwater mining can deplete aquifers, impacting both surface water levels and groundwater availability.
What are the features and processes of groundwater systems?
Groundwater systems consist of aquifers, which are underground rock formations that hold water. Groundwater recharge occurs when precipitation replenishes these aquifers. Groundwater flow can move through the aquifer and eventually discharges into streams, lakes, or oceans. Groundwater systems play a vital role in providing drinking water and supporting ecosystems.
When limestone on the surface is dissolved by ground water it forms?
When limestone on the surface is dissolved by groundwater, it forms features such as caves, sinkholes, and disappearing streams, through a process known as karst topography. This occurs because limestone is a rock that can easily be dissolved by the slightly acidic nature of groundwater, creating these unique geological formations over time.
What is the distribution of contaminated groundwater called?
The distribution of contaminated groundwater is commonly referred to as groundwater contamination. This occurs when pollutants are introduced into the groundwater, affecting its quality and making it unsuitable for drinking or other uses. Measures such as remediation and monitoring are often taken to address and mitigate groundwater contamination.
The lowering of the water table that occurs when water is pumped from a well is called?
the cone of depression

What is it called when two streams join together?
When two streams join together, it is called confluence. This natural phenomenon occurs where two rivers or streams meet and merge into a larger body of water.
When will a cone of depression stop enlarging?
A cone of depression will stop enlarging when the rate of groundwater extraction equals the rate of groundwater recharge in the aquifer. This occurs when the water table stabilizes as the inflow of water meets the outflow due to pumping. Factors such as geological conditions, distance from the pumping well, and the aquifer's permeability also influence this stabilization process. Once equilibrium is reached, the cone of depression will remain relatively constant in size.
What is groundwater overuse?
Groundwater overuse occurs when the rate of water removal from an aquifer exceeds the rate of water recharge. This can lead to depletion of the groundwater supply, causing lower water levels, reduced stream flow, and land subsidence. Groundwater overuse can also result in saltwater intrusion in coastal areas.
What occurs when two streams flow perpendicular to each other?
