. Describea typical stress-strain curve and the relationship between the segments of the curve and stress and strain.

the relationship between stress and strain that a particular material displays . it's unique for each material . it's is found by recording amount of strss at different values of strain. it is the stress point at which a specific material breaks under a given stress  in a typical stress-strain curve ,  the breaking strength is less than the ultimate strength

Explanation:

thermophiles, notice the prefix thermo.

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.
