Answer: D. demographers
Explanation:
When planning for the future of a city, the urban planners need to ensure that the city is able to afford its current and future residents with the facilities needed to provide them with the maximum welfare possible.
To do this the urban planners should reach out to demographers. Demographers study human populations with a view to analyse and ascertain various characteristics such as size, composition, how they are distributed within a geopolitical zone and most importantly, how they will change overtime.
For urban planners to plan for a city that will take care of future residents as well, they would need to know how the kind of future residents they are planning for and this is when they will turn to demographers whose job it is to study and possibly predict future population.
Answer:
Basalt, sedimentary rock.
Explanation:
- The reason why the continental crust differs from the oceanic crust is much different in its compositions. The continental crust is thin and less dense , is made of sedimentary and metamorphic rocks than the oceanic crust and is made of lighter elements. The tectonic plates move the composition to the rocks.
The correct answer is the peacock. The plumage found in Indian peacocks are because of the Bragg reflection phenomenon.
Explanation:
Bragg's law, or Wulff–Bragg's position, a special event of Laue diffraction, gives the plans for coherent and incoherent scattering from a crystal lattice. When X-rays are conflicted on an atom, they make the electronic cloud move as does an electromagnetic wave and it is observed in peacock.
The correct option is LOESS.
Loess refers to a compacted yellowish deposit of wind blown sediments which is usually found extensively in the mid latitudes. Loess is formed by the accumulation of dust that had been blown by the wind. Scientists believed that about 10% of the earth's land area is covered by loess.<span />
