Answers
Answer:
a. Epicenter
b.stratum
c.faulting
d.anticline.
Explanation:
all answer has been given on short questions
Answer:
(a) The location below the earth's surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter.
(b) As a mantle plume reaches the upper mantle, it melts into a diapir. This molten material heats the asthenosphere and lithosphere, triggering volcanic eruptions.
(c)fracture – any surface of discontinuity within a layer of rock. ... joint – a natural fracture in the formation in which there is no measureable shear displacement. shear fracture – fractures across which shear displacement has occurred. fault – (in a geologic sense) a fracture surface upon which there has been sliding.
(d)The upfold is called an anticline.
