Answer: Gneiss
Explanation: Gneiss is a metamorphic rock formed from shale at very high temperature and pressure condition. They exhibit a preferred alignment or orientation of platy minerals called foliation. They are coarse grained and exhibit gneissose banding. They are formed from highest grade regional metamorphism with temperature between 450 - 600 degree celcius and pressure between 800 - 1000 mega pascal. They generally occur in cores of fold mountain belts where mountain ranges have been eroded.
Answer:
velocity = 7.30 m/sec
23 m depth wave will feel bottom
Explanation:
given data
wavelength = 46 meters
wave period = 6.3 second
to find out
velocity and At what water depth will a deep water wave begin to feel bottom
solution
we get here velocity that is express as
velocity =
.............1
velocity =
velocity = 7.30 m/sec
and
wave base =
× wavelength .................2
wave base =
× 46
wave base = 23 m
here water depth more than 23 m will producer will circular wave less than elliptical wave
so 23 m depth wave will feel bottom
I would say...
-straight
- durable
-layered
