I think it’s ABE Sorry if it’s wrong
The groundwater is the largest freshwater reservoir on Earth in liquid form. These waters though are not isolated from the rest of the freshwater, but instead they are connected with the streams, thus they affect them heavily.
The groundwater has been heavily used in the last century, and it has been depleted. The depletion of the groundwater has been the result of over usage, or to put it simple, more water has been extracted than what naturally is replenished.
This has been causing more and more problems. Apart from the groundwater resources getting depleted and than be unusable, the depletion of their water has resulted in lowering of the level of water of the streams, as the streams have been receiving less and less water. Also, because there is much less water and it mixes with lot of ground and rocks, the water quality has been becoming worse and worse, and if this trend continues it can have devastating effects.
When a farmer uses no-till farming methods, this means only organic fertilizers are used. The correct option among all the options that are given in the question is the second option or option "b". This kind of farming increases the water retention rate of the soil and also stops soil erosion.
Hello,
I don’t know which region are you talking about but I have this :
In the middle of immense desert expanses, the oases appear like islands of greenery. To irrigate crops, sedentary peasants use wells or underground galleries called foggaras. They bring the water to the foot of the plants through a network of small earthen channels
Hope it helps a bit!
Byye and don’t forget I’m proud of you!!<333
Earth's mantle has kept contributing to the Earth's atmosphere through a process called degassing. During this process, gases are emitted from the magma in the mantle and are transferred into the atmosphere through tectonic procedure such as ocean ridge spreading and volcanism.
