How is the earth’s groundwater and surface water replenished

The replenishment of groundwater takes place by precipitation, and on the basis of the geology and local climate, it is non-uniformly dispersed in both the quantity and quality. When the snow melts or rain falls, the evaporation of water takes place, some flows overland and gets gathered in streams, some get transpired by plants, while some infiltrate into the cracks or pores of the rocks and soil. After the requirements of water for the plants and soil gets fulfilled, the excess water gets infiltrate to the water table.  

Similarly, the surface water, that is, the lakes, streams, rivers, and others get replenished via the process of precipitation. This can be in the form of hail, snow, rain, and others. The ice or snow melt also recharges surface water.  

a mercury barometer is a device that uses the physical properties of mercury in a tube to measure barometric pressure. mercury barometers are used for : -

1. measurement of atmospheric pressure  

2. determining the altitude of a place

3. weather forecasting

4. calibration and checking of aneroid barometers

5. application in fluid mechanics

6. measurement of pressure in aircrafts

7. surface weather analysis

8. preparation of barographs

9. usage in physical sciences like physics, astronomy & chemistry

10. preparation of aircraft altimeters

characteristics of mercury barometer : -

1.used to define and measure atmospheric pressure.

2.on the average at sea level the column of mercury rises to a height of about 760 mm.

3.this quantity is equal to 1 atmosphere.

4.it is also known as standard atmospheric pressure.

5.a barometer in which the weight of a column of mercury in a glass tube with a sealed top is balanced against that of the atmosphere pressing on an exposed cistern of mercury at the base of the mercury column, the height of the column varying with atmospheric pressure.

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
