1. Does elevation play a factor? If so, can the elevation be changed to protect the homes? 2. Could the residents build a structure that would prevent a tsunami from reaching the community? What would this structure look like? How would the residents build it? 3. What could limit the erosion of the beach?

Yes.

Explanation:

Yes, elevation play a great role and has the ability to protect homes from natural disasters such as flood and tsunami etc. The residents build a hard structure of wall along the beach that would prevent a tsunami from reaching the community and also built homes at higher elevation. The residence built it with the help of government and this wall is also effective in reducing the erosion of the beach.

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
