Answer:
Add the thermal R values of each wall layer.
Explanation:
Fiberglass insulation R value, sheetrock, sheathing, siding etc. All sum together to one composite opposition to heat transfer/loss.
Q= U x A x Delta T
Q= heat transfer btuh
U= 1/R inverse of resistance
A= area of surface
Delta T is temerature difference across the wall.
Answer: The movement of tectonic plates
Explanation:
Tectonic plates are the part of the earth's crust that both the ocean and land rest on. These plates are constantly moving as a result of currents in the mantle.
These movements cause stress on the surface which has the effect of fracturing rocks and thereby creating/ forming faults in the earth's crust. Sometimes faults form when these plates move away from each other and sometimes they are formed when they push into each other.
Number three number three number three I’m not 100% sure though
