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.
Answer:
It made significantly better predictions of planetary positions in our sky
Explanation:
Of the following statements the one which was not a major advantage of Copernicus's Sun-centered model over the Ptolemaic model is that it made significantly better predictions of planetary positions in our sky. Both the model made similar predictions of planetary position in our sky. In fact the Ptolemaic model was even better than the Copernicus's heliocentric model when it came to positioning of planets.
The climate is continental. cold winters and mild summers. hope this helped
The Brazilian highlands are not in Brazil
<span>
Basically, the meteor caused there to be an increase of Carbon Dioxide, and less oxygen in the atmosphere :P I really hope this helps
