Question
All of the following are lines of evidence for plate tectonics except for____ A. Similar rocks on continents separated by an ocean B. The presence of metamorphic rocks in mountain belts C. Evidence of glaciation of the same age on continents separated by oceans. D. Jigsaw-puzzle shape of the continents You can drive a rock to melting by which of the following? A. Raise its confining pressure and cool it B. Lower its confining pressure and cool it C. Raise its confining pressure and heat it D. Lower its confining pressure and heat itExplanation / Answer
the plate tectonic theory is one of the most significant theory for deriving earth's geology . trhe above all statements for the evidence of plate tectonic is true except the jigshaw-puzzle shape of continents.
according to plate tectonic theory- along the sea floor spreading zones, the continents are separating. when they spread past the magma comes out to the surface and becomes new continent crust. as the tectonic plate moves away from the spreading zone,they collides.sometimes the edges of two different plates grinds against each other horizontally forming areas known as, "transform boundary" ( experiences most of the earthquakes).
JIGSHAW-PUZZLE SHAPE OF CONTINENTS- the shape of north and south america, south africa, india is like jigshaw puzzle. this is due to the earth is twisting in the nothern and southern hemisphere in opposite directions9 clockwise and anticlockwise); by the same time it squeezes the poles. due to this squeezing and twisting slowly the matter from inner earth came out from equatorial part regularly and dry on different plates forming continents.
