When the groundwater flow intersects the ground level, it forces the water to come out to the surface forming a spring.
The study of changing atmospheric composition along with the ice cores, helps in determing the age upto 800,000 years. But recently, a new discovery has made, in which the ice cores helped in dating back to about 1.5 million years.
