Freshwater supplies (resources) can be increased by using the groundwater which is used to supply cities and grow food is being pumped from the aquifers in some areas faster than it is renewed by precipitation.
So, from another way in which freshwater supplies can be increased in a water stressed area is through the use of aqueducts, tunnels, and underground pipes in order to transfer stream runoff collected by dams and reservoirs in water-rich areas. So, in some areas it is renewed by precipitation.
The freshwater supplies can also be increased by large dam-and-reservoir systems and water transfer projects which thus have greatly expanded water supplies in some areas, but this has also a negative impact, as it have also disrupted ecosystems and displaced people.
Hence, such water transfers have benefits, while they also create environmental problems.

What is probably the single most important, original, depositional feature in sedimentary rocks?.
The most important, original, and depositional feature in sedimentary rocks is bedding.
What is the meaning of bedding in terms of sedimentary rocks?Bedding is referred to as the most depositional and prominent feature in sedimentary rocks in the form of horizontal stratification. The boundaries between the different sediment layers are a function of these bedding lines. The flat and parallel surface is where most of the sediment was deposited. There is also a steeper layer of sediment known as cross-bedding where sediment is deposited on the edge or slope area due to strong wind or water waves.

Methane gas will be released the most into the atmosphere and intensify the global warming due to the melting of tundra.
What is Methane gas?Methane is non-toxic and poses no danger when inhaled in limited amounts. However, when large amounts of natural gas or methane displace the air, it can run out of oxygen and suffocate. It is mainly used as a fuel to generate heat and light. It can also be used in the formation of organic chemicals. Methane can form from the decay of natural substances and is commonly found in landfills, wetlands, septic tanks and sewers. The largest sources of anthropogenic methane emissions in the United States are oil and gas systems, livestock enteric fermentation, and landfills.Methane has more than 80 times the warming potential of carbon dioxide for the first 20 years after entering the atmosphere.

What is probably the single most important, original, depositional feature in sedimentary rocks?.
Bedding or stratification is probably the single most important, original, depositional feature in sedimentary rocks.
For instance, bedding is the division of sediments into layers that either differ from one another in terms of textures, composition, colour, or weathering traits, or are divided by partings, which are small spaces between adjacent beds. Bedding is a sign of changes in depositional processes that could be brought on by seasonal variations, climatic changes, shifting river or delta positions, or tectonic shifts. Partings could be the result of non-deposition for a few decades to several centuries. In practically any depositional setting, bedding can form.

The spiral arms of the galaxies are the the main production centres of young stars. The more gas and the dust available, the greater the fraction of the galaxy that can be involved in the star formation. These high-production galaxies actually tend to be dominated by their spiral arms and have relatively small central bulges. Their arms contain actually more clusters of very luminous stars and the more luminous nebulae (HII regions).

The reason for the formation of vesicles in igneous rocks is the rapid cooling of lava flow by water.
What is vesicles?According to the explanation by Bates and Jackson (in their book called The Dictionary of Geologic Terms, 1984), the definition of vesicles is a small cavity in an aphanitic or glassy igneous rock, formed by expansion of a bubble of gas or steam during solidification of the rock. Igneous rocks that have vesicles are just igneous rocks that are formed from the cooling of molten magma that reaches the earth's surface or this type of magma is referred to as lava. The lava is usually mixed with water when it flows over the earth's surface.
Based on the expert's explanation, it can be said that vesicles in rocks are formed when magma comes out to the surface of the earth and then cools and hardens rapidly so that the gas trapped inside the rock has not had time to be released which then forms a vesicular texture.
In conclusion, the cause of the formation of vesicles in rocks is rapid cooling of a lava flow by water.
