What rocks would exhibit evidence of partial melting?
Rocks such as migmatites, which are a mixture of igneous and metamorphic rock formed through partial melting, would exhibit evidence of this process. Additionally, some granites and gneisses can show signs of partial melting due to the presence of melt pockets or segregated mineral assemblages.
Which process in the rock cycle causes magma to form?
Magma forms through the process of partial melting of rocks in the Earth's mantle. This can occur due to the intense heat and pressure in the mantle, causing certain minerals within the rocks to melt and form magma.
Why are volcanic chains associated with convergent boundaries?
partial melting occurs due to subduction.
What are melting regions in the mantle called?
Melting regions in the mantle are called melting anomalies or melting zones. These are areas where the temperature and pressure conditions are conducive for the partial melting of mantle rocks, leading to the formation of magma that can eventually erupt at the surface as lava.
What is the name of semi-molten rock?
we can call it an igneous rock because it coming from partial melting of preexisting rocks

Can Small amounts of water can lower partial melting temperatures in silicate rocks?
Yes, small amounts of water can lower the partial melting temperatures of silicate rocks by promoting the breakdown of mineral structures, reducing viscosity, and increasing mobility of magma. Water can act as a flux, helping to facilitate melting at lower temperatures.
What happens when water is added to rock in the mantle?
When water is added to rock in the mantle, a process called hydration occurs where the water reacts with the minerals in the rock to form new minerals. This can lead to changes in the rock's composition, structure, and physical properties. Additionally, the presence of water can lower the melting point of the rock, potentially leading to the formation of magma through partial melting.
Would pressure play a role in partial melting?
In so far as pressure affects the melting point of substances, the answer is yes.
Which process is the key concept behind smelting metals from ores?
Partial melting
What is thought to form by partial melting and in situ crystallization of the melted portion?
migmatite
What are the causes of partial deaftness?
Some possible causes of partial deafness include prolonged exposure to loud or constant noise, disease and injury.
What is responsible for the partial melting of peridotite beneth the mid-ocean ridges?
An increase in pressure.
Why are volcanic chains associated with convergent boundaries?
partial melting occurs due to subduction.
