Solution

(58)A- Conduction -does not operate in interior of the earth.

(59)C- Pangea is the continent praposed by Alfred wegner.

(60)B- An ion is the an atomthat has more or fewer electrons that it should.

(61)A-The silicates are the mineral class that account for mre than 90% of the Earth\'s Crust.

(62)ABCD - All property that participate for the formation of the exterior of the earth Crust.

(63)C-Age of the universe is 13.7 billion years ago.

(64)A- Ionic bond is the strongest.

(65)B-Effervescence is the tehnique would be best for identify calcite.

(66)A- Rock

(67)D-Silica

(68)C-Independent silicates

(69)A-Sodic and Calcic

(70)B- Along divergent plate boundaries -oceanic crust generated

(71)A-Rhyolite

(72)D-Parent rock

(73)B-Black smokers

(74)D- Crust

(75)A-18 - Atomic mass= number of proton +number of neutran for ant element
