Can Small amounts of water can lower partial melting temperatures in silicate rocks?
The addition of water can lower partial melting temperatures in silicate rocks.
Basalt is generated by?
partial melting of mantle rocks
What happens when water is added to rock in the mantle?
It causes a lowering of the melting temperature of the material, which in turn can cause partial melting of the mantle material leading to the formation of magma.
Can Small amounts of water lower partial melting temperatures in silicate rocks?
Yes, Read A Book next time
Most basaltic magmas are believed to form by partial melting of granite in the lower crust and upper mantle?
This statement would be considered incorrect. Basaltic magmas originate from the melting of mantle rock or oceanic crust.
Can Small amounts of water can lower partial melting temperatures in silicate rocks?
The addition of water can lower partial melting temperatures in silicate rocks.
Basalt is generated by?
partial melting of mantle rocks
What is the adjective of vacuum?
of containing, producing, or utilizing a partial vacuum
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
Describe how the presence of ocean water in crustal rocks might affect the formation of magma?
Since "Wet" rock melts at a lower temperature than "dry" rock, this helps initiate partial melting in subduction zones. The subducting material is saturated with sea water which helps speed up the melting process. Steam rises into the overlying lithosphere and asthenosphere and causes the formation of vast quantities of magma
What is a dilapidated?
In a condition of partial ruin or disrepair
What is the condition of partial lack of hair?
ALOPECIA
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.
What role does asthenosphere play in generating magma at a convergent boundary?
At an oceanic subduction zone, the athenosphere is subducted under continental lithosphere, or under other oceanic lithosphere. Friction between these plates causes heat that creates magmas. At a divergent boundary upwelling mantle (athenosphere) decompresses due to reduced pressures, allowing magma to form. This magma is extruded onto the seafloor as pillow basalts, and beneath the seafloors as massive gabbros and sheeted (gabbro) dikes.
