Answer:
Explanation:
Water scarcity already affects every continent. Around 1.2 billion people, or almost one-fifth of the world's population, live in areas of physical scarcity, and 500 million people are approaching this situation. Another 1.6 billion people, or almost one quarter of the world's population, face economic water shortage (where countries lack the necessary infrastructure to take water from rivers and aquifers).
Water scarcity is among the main problems to be faced by many societies and the World in the XXIst century. Water use has been growing at more than twice the rate of population increase in the last century, and, although there is no global water scarcity as such, an increasing number of regions are chronically short of water.
Water scarcity is both a natural and a human-made phenomenon. There is enough freshwater on the planet for seven billion people but it is distributed unevenly and too much of it is wasted, polluted and unsustainably managed.
Answer:
Option (1)
Explanation:
Isohyets- This are the lines that connects the points of equal amount of rainfall that occurs at any given period of time.
Contour lines- This are the lines of equal elevation.
Isotherms- This are the lines that connects the points of equal temperature.
Isobars- This are the lines connecting the points of equal atmospheric pressure.
Isogrids- This are a type of half hollowed-out structure that is created mostly from a single metallic type of plate with hard triangular rib like structures that are commonly known as stringers. This are very light and hard in comparison to other substances, This are very costly to build, so they are basically used for the applications that are usually related to the spaceflight and also used in the field of aerospace.
Thus, the isogrids are not a common type of isoline.
Hence, the correct answer is option (1).
Answer:
1 ) buprenorphine treatment
2) Convenience goods and services
3) furniture
4) electrical goods
5) hairdressing,
respectively
Explanation:
Threshold is the minimum population and range is the maximum distance needed to sustain a good. As such, it'd make sense for buprenorphine treatments (a rare service) to have a low threshold since not too many people will be buying it, but it's still sustainable since it's expensive.
"Medium" is a loose definition so I would say any convenience good or service would be good for this one.
Furniture would have a large threshold because a lot of people are moving and in need of furniture.
People are willing to travel great distances to get electrical goods because they're specialized goods and you can't just find them anywhere, thus, it has a large range.
Things like hairdressing aren't worth traveling great distances to receive so they have a small range.
