The Earth's upper mantle is mainly made of peridotite, an ultramafic igneous rock with lots of olivine crystals. Which type of magma can be produced when the upper mantle undergoes decompression melting of the upper mantle peridotite at mid-ocean ridges? - correct answer -Basaltic Seismic studies of the earth have shown that the platnet's interior is made of a few layers with distinct seismic signatures and chemical compositions. The major layers of the planet include (from innermost to the o...

What is the principle of superposition? - correct answer -In a sequence of undisturbed layered rocks, the oldest rocks are on the bottom. What is the principle of horizontality? - correct answer -1. Layered strata are deposited under the influence of gravity as horizontal or nearly horizontal or nearly parallel to the Earth's surface What is the principle of faunal succession? - correct answer -Sedimentary strata in an outcrop contain fossils in a definite "time" sequence. The same sequ...
