Pls Mark as brainliest

Explanation:

1.Because hydrogen is a highly combustible gas and oxygen is the supporter of combustion since water does not show the property of hydrogen and oxygen therefore it is a compound as compound does not show the property of a constituent.

2.Ground water depletion is the phenomenon in which the water from the earth (i.e., ground water) is lost due to many reasons.

 we require water for homes, and also for agriculture and industries, Groundwater is becoming scarce in many parts of the world due to heavy dependence on it. In several states of the country groundwater levels are dangerously low, and are still declining. Deforestation is the main cause of groundwater depletion.

replenishment of ground water can be done by rain water harvesting and reforestation or by using groundwater with care and wasting zero quantity of it.

Answer 2

1. Water contains hydrogen and oxygen so it is a compound. A mixture has elements and compounds;but water doesn't contain any compound, so it cannot be called as a mixture.
2. Groundwater replenishment happens through direct recharge and in-lieu recharge. Water used for direct recharge most often comes from flood flows, water conservation, recycled water, desalination and water transfers. ... Two recharge methods are used: direct spreading and aquifer injection.
