Answer:
Partial melting occurs when only a portion of solid is melted. It is thus enriched in the chemical components of minerals with lower melting temperatures and the remaining unmelted portion of the rock is composed of minerals with highest melting temperatures. Partial melting preferentially enriches melts with incompatible elements.
Partially melted rock do not usually experience complete melting inside the Earth, due to their different chemical composition and their melting points.
It is thought that partial-melting processes play a major role in generating more-defined liquids from less-evolved ones, so that many basalts may be the result of partial melting in the upper mantle, and many granites may have derived partly or completely from the partial melting of continental crust (anatexis).With increasing temperature and pressure, the subducted oceanic crust (of basic composition) first undergoes metamorphism and then begins to melt or release watery fluids; this material rises into the overlying mantle, which may also begin to melt, giving rise to intermediate magma.
C. Hawaii
plz mark me BRAINLIEST:))
Answer:
This is because of isostatic adjustment.
Explanation:
The mountains of the Himalayas keep growing because of the isostatic adjustment. it allows for a gravitational balance in the Himalayan mountain region, which causes tectonic plates to float below these mountains. This fluctuation occurs in the densest part of the asthenosphere. This density, together with the force of gravity, causes an increase in the height of the tectonic plate that sinks more and more. As the tectonic plate sinks, inversely, this plate rises, when its weight decreases, and it is this rise that causes the mountain to grow.
Mostly fractures than cleavage
Answer:
gamma diversity
Explanation:
Gamma diversity
The name was given by R. H. Whittaker ,
<u>Gamma diversity </u>= the total species diversity in the landscape .
<u>Beta diversity</u> = the differentiation among the habitats .
<u>Alpha diversity </u>= the mean species diversity in sites , or at local scale .
The product of alpha diversity and beta diversity together gives the gamma diversity .
