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...

Nicholas Steno Answer This man became a catholic bishop, challenged the tear theory, and is known as the Father of Stratigraphy Law of Original Horizontality Answer This principle states sediments are deposited under the influence of gravity as nearly horizontal beds. Law of Superposition Answer This principle states that top layers of rock are younger than bottom layers. Law of Faunal (Flaural) Succession Answer Sedimentary rock strata contain fossilized flora and fauna that these foss...

EAS 201 Exam Questions With Verified Answers Principle of superposition - ANSWER oldest layer = bottom, newest layer = top Principle of original horizontality - ANSWER sediment originally deposited in layers that were nearly horizontal and parallel to the surface on which they were accumulating, tilted rocks = crustal disturbance Principle of original lateral continuity - ANSWER all strata extend in all directions until they terminate by THINNING at the margins of the basin, end...

Earth Science Lab Final (Answered) Complete Verified Solution Noncomformity 1) Younger sedimentary rocks on top of older metamorphic or intrusive igneous rocks 2) Imply period of uplift of deeply buried rocks Three types of uncomformities angular uncomformity, disconformity, and noncomformity Radiocarbon dating Using the carbon-14 isotope to date very recent events (Half-life of carbon-14 is only 5,730 years) (Only useful for dating events from historic past and very recent geolog...

Fossils Science Olympiad Exam Questions And Answers 100% Verified Conditions required for a plant or an animal to become fossilized - answerHard body parts (bones, teeth, shells) - soft body parts will not fossilise, but may leave behind trace evidence (e.g. imprints) -Preservation of remains (protection against scavenging, erosion and environmental damage) -High pressure to promote mineralisation of remains (i.e. turn hard body parts into fossilised rocks) -Anoxic (low oxygen) condition...

Catastrophism correct answers the concept that earth was shaped by catastrophic events of a short-term nature; the present is the key to the past; James Usher constructed a chronology of human and Earth history; determined that the Earth was created in 4004 B.C.; The chronology gained wide acceptance during the mid-1600s by the scientific and religious leaders Uniformitarianism correct answers the concept that the processes that have shaped the earth in the geological past are essentially the...
