Explanation / Answer

;answer 11: Mesosphere

answer 12:Solid

answer 13: Iron/Nickel

answer 14:false actually crust is small part of lithosphere

ansewer 15: ductile solid

ansewer 16: ductile solid

answer 17: the crust actually crust is defined based on chemical properties( sial and sima)

answer 18: transform

answeer 19: divergent boundaries

answer 20 subduction zones

answer 21 earthquake alond boundary line and they are shallow earthquake

answer 22 transforms

answer 23 subduction

answer 24 deep trench

answer 25 divergent
