Answer 1
Answer:

Answer:

Yes, The oceanic crust is more dense but thinner than the continental crust,

Explanation:

  • As the continental crust is  35-40 km, more thicker than that of the oceanic crust and it accounts for a mean surface elevation of three miles. Hence the continental crust is lighter than the oceanic crust and thus the less dense crust floats or stays at the top but the thickness of the oceanic crust is 7 to 10 km.
  • As the surface crust is a layer of the granitic and the sedimentary and metamorphic rocks and about 40% of the earth's surface is formed by this plate or continental crust and rest 60% is by the oceanic crust which is made of basalt. Both are less dense than the mantel.

Unlike hierarchical diffusion contagious diffusion (2 points) A.spreads from urban areas to rural areas
B. Originates from a center of power
C. Has a group impact across socioeconomic groups
D. Involves the spread of ideas
E. spreads slowly over a long period of time

Answers

C. Has a group impact across socioeconomic groups 

Final answer:

Unlike hierarchical diffusion, contagious diffusion impacts across socioeconomic groups because it involves a concept or idea spreading without regard to social status. This is unlike hierarchical diffusion where ideas originate from a power center and trickle down to others.

Explanation:

Unlike hierarchical diffusion, contagious diffusion option C 'Has a group impact across socioeconomic groups' is correct. In contagious diffusion, a concept or idea spreads outwards from its source to all adjacent groups or individuals, regardless of their social status. This is different from hierarchical diffusion where ideas or concepts start with an individual or group of authority or power and then trickle down to other people. For example, a new slang term could spread rapidly through a school (contagious diffusion), regardless of social divides such as 'popular' vs. 'unpopular' students.
