Community is a place where every human being has to live
The convection currents are the ones that create the force that breaks up and moves the crustal plates on the surface of the planet. By moving the crustal plates, the convection currents contribute to the formation of different types of plate boundaries, including the divergent plate boundaries.
The divergent plate boundaries are the boundaries where two plates are moving away from one another because the convection currents are dictating that kind of movement from bellow them. As they move away from each other, they leave a gap between them, and the convection currents push up a lot of magma towards the surface. The magma cools of very quickly in the water, thus forming rocks constantly, rocks that little by little start to make a big mas, that eventually turns into an underwater mountain, or rather a mid-ocean ridge.
B = 0.4
b = 0.6
Explanation:
From the question we derive that;
BB = 16%
Bb = 24%
The gene frequency for BB = 16/100 = 0.16
To find allelic frequency of B;
B = √0.16 = 0.4
Remember Hardy Weinberg rule that all allelic frequencies of a gene must sum up to 1;
p + q = 1
If p = 0.4
q = 1 – 0.4 = 0.6
b = 0.6

Answer:
Minimizing economic, environmental, and human costs related to extreme weather is a difficult problem for public infrastructure because New York´s geography feautures include 520 miles of shoreline, marshes, beaches, harbors and waterfonts implying an big magnitude of costs requiring a wide range of adaptive strategies to bulid up resilience to hazard from extreme weather, but not as an immediate benefit.
Explanation:
New York has always been a waterfront city, therefore Hurricane Sandy’s significant flood and destruction reminded the governments on precedents around the world about extreme weather global complex issues that the city is facing as an urban waterfront community.
New York City with its unique features, coped with storm´s coastal flooding disaster and recognizes it needs to cope with the challenges of increasing risk that climate change, sea level rise and coastal storms involve. But the storm city´s resilience imply high-costs-strong measures to plan for coastal risks aid in short- and long-term robust infrastructure projects considering the special design for waterfront communities by the means of making the city safer and healthier, but still vibrant and prosperous, vital and sus
tainable.
Although critical, planning for the future of these projects depends on budget management associated with each strategy for New York City comprehensive waterfront plan, as this framework requires gigantic public and private investment for ensuring healthy waterways, a strong port, the ecological protection of nat
ural habitats, the public’s enjoyment of the shoreline, and the economic benefits of in our waterfront trying to understand the magnitude and benefits in the future and in case of disasters.

Explanation:
Soil erosion is the displacement of the upper layer of soil; it is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice, snow, air, plants, animals, and humans
