Ans: Strain is the change in shape or size of a solid object.


Elastic: an object changes shape when forced by springs back to original
when force is released.


Plastic/Ductile (very plastic): the object permanently changes shape or
deform when forced.


Brittle: not plastic; fractures instead of bending.


Question: Types of energy


Ans: Work: W=FD


PE


KE


S. Heat


L. Heat.


When gases condense into liquids or when liquids freeze into solids, latent
heat is released into sensible heat.


Question: Linkages exist


Ans: Earthquakes -> landslides + tsunamis, hurricanes -> flooding + coastal
erosion.

Question: Energy Conservation


Ans: Kinetic energy of an asteroid is converted into sensible and latent
heat when it strikes Earth.


Question: Carrying Capacity


Ans: The pop can be sustainably supported within a given domain, given
overall factors.


Question: 3 TYPES OF STRESS


Ans: 1) COMPRESSION


2) TENSION


3) TRANSVERSE.


Question: Strain


Ans: ..is the deformation in response to stress, objects change size, shape
or volume. Elastic is temp change, and reversible. Plastic is permanent
change is shape or size, irreversible. Brittle causes faults. Low temp and
low confining pressure, and at high strain rate.


Question: Earthquakes strain


Ans: Brittle deformation.
