What causes crystalline layers through conglomerate rocks these layers cut through individual rocks?
The conglomerate must have been subjected to stresses sufficient to cause fracture in the individual rocks making up the conglomerate. The cracks were then infilled by minerals precipitating from fluids which were migrating through the rock.
How does a foliated metamorphic rock from?
Schist is a typical foliated metamorphic rock. Initially, one merely has a laminated sedimentary rock. When this is subjected to heat and pressure, then some of the old minerals are destroyed and new ones formed from the available assemblage. From the types of new minerals formed, one may deduce the heat and pressure of the metamorphism. The date of the metamorphism is estimated by dating the mineral last formed - the one with the lowest freezing point. [Commonly mica]. The rock may then be subjected to further stresses which will produce folds of some complexity. This may be followed by intrusions of granites or volcanics.
What is plastic memory?
If certain plastics (take for instance PTFE) is subjected to stresses below its yield point then it may be subjected to permanent deformation. This deformation will induce certain strains through out the material. If the plastic is heated up, these strains tend to relax which allows the plastic to return to its original shape. This is often refered to as "plastic memory".
Why might metamorphic rocks be more likely to show bands of color than igneous rocks?
Some metamorphic rocks display foliation, a distict banding due to the alignment of like minerals due to high pressures and temperatures. Igneous rocks , especially those that form below the ground from cooled magma are more homogenous in appearance because of the interlocking crystalline structure among the composite minerals.
What stresses the South American plate and the African Plate?
Far-field stresses triggered by portions of the northern boundary stress the African plate. Intraplate stresses are the driving forces in the South American plate
Fracture in vertebrae subjected to extreme stresses?
compression
What fracture in vertebrae is subjected to extreme stresses?
Compression Fracture
What are the major stresses to which all aircraft are subjected?
Bending, Shearing, Torsion, Shearing, and Compression.
What type of connective tissue that strengthens and supports areas subjected to stresses from many directions?
Dense irregular connective tissue
What causes crystalline layers through conglomerate rocks these layers cut through individual rocks?

When a horizontally laid out of beam is subjected to a vertical load which part expresses compressive stresses?
If the load is from the top pointing down, compessive stress is at the top and tension at the bottom
What is difference between von mises and principle stress?
Whenever an elastic body subjected to loads in its 3 dimensions, the stresses will get developed along the principal axis of the body. These are the principal stresses. These stress should not exceed the yield stress of the material. Von Mises (1913) postulated that, even though none of the principal stresses exceeds the yield stress of the material, it is possible for yielding of the same from the combination of stresses. The Von Mises criterion is a formula (refer any textbook which content failure theories for Ductile Materials) for combining these 3 stresses into an equivalent stress, which is then compared to the yield stress of the material.

What will happen if you drop nuclear liquid?
Your question deals with nuclear fuel liquid. fluid fuels are not subjected to the structural stresses of solid fuels. If you drop liquid nuclear fuel, and you are not wearing protective gear, the Gaseous will sicken you and kill you.
What is Electric field stress?
An Electric field stress depends on the mechanical strength of the materials and the stresses that are generated during their operation. During high voltage applications, the dielectric strength of insulating materials are developed when subjected to high voltages.
