As you can see from the way the Earth is structured earthquakes are going to happen. Yet, what in the work you have just done gives you connections to or ideas of ways to attack the problem? In other words, given what you've just done, what is most promising idea to help people survive? (So basically answer on how we can predict earthquakes from the structure of the earth. Like the mantle and crust etc)

Adiver named jacques observes a bubble of air rising from the bottom of a lake (where the absolute pressure is 3.50 atm) to the surface (where the pressure is 1.00 atm). the temperature at the bottom is 4.00 ∘c, and the temperature at the surface is 23.0 ∘c. what is the ratio of the volume of the bubble as it reaches the surface (vs) to its volume at the bottom (vb)? if jaques were to hold his breath the air in his lungs would be kept at a constant temperature. would it be safe for jacques to hold his breath while ascending from the bottom of the lake to the surface?
