CEE 340 Exam 1 Engineering Geology
Differentiation refers to the system wherein the earth:
became chemically segregated due to melting and sinking of iron
In order to provide an explanation for the shipping of warmth through the earth, it is essential
to invoke the technique of
Convection
One quarter in the earth deforms plastically and might even be in part molten. This is the
Asthenosphere
The lithosphere is high-quality described as
a inflexible top layer of the earth that actions over the earths surface above the plastic
asthenosphere.
In order to be categorised as a mineral, a substance have to be
inorganic, certainly going on, crystalline.
All crystals of a mineral will have the same
chemical composition (or chemical compositions that adjust between constant limits),
attitude between corresponding crystal faces, inner structures
Cleavage is maximum diagnostic for which of the following mineral.
Hornblende
The silicate mineral institution incorporates all however which of the subsequent minerals?
Contains: quartz, plagioclase, olivine
Does NOT: Dolomite (carbon)
Which silicate mineral has an remoted shape?
Olivine (silica tetrahedral)
The clay minerals fall into which of the silicate mineral corporations?
Sheet
, Non-ferro-magnesian silicate
plagioclase
quarts can regularly be recognized by using its hardness and
absence of cleavage
striations are used to become aware of
plagioclase feldspar
Vitreous luster is function of
quarts
quartz and feldspar are members of the
framework silicates 3-d
Extrusive and intrusive igneous rocks can be outstanding by means of
texture
Aphanitic texture is characteristic of
extrusive rocks
if a specimen of granite had been slowly heated, which mineral would melt first
quartz
Porphyritic texture suggests.
Slow cooling, followed by way of speedy cooling.
Which of the following is an igneous rock?
Basalt
the texture of igneous rock is decided with the aid of the fee at which magma
cools
an igneous rock with honestly visible mineral grains has a ---- texture
Phaneritic
