Answer:
c. The downgoing slab takes along water, and that water lowers the temperature at which rock melts to allow melting in and near the slab.
Explanation:
A subduction zone occurs when one of the plates at convergent boundaries, an area where tectonic plates meet, is an oceanic lithosphere.
These oceanic plates are high in temperature on formation but as they cool, they descend into the mantle below. This descent applies pressure until water is liberated from the lowering crust. The water in turn rises into the surrounding mantle and lowers the temperature at which the rocks melt to produce magma which are partly melted rocks.
This liberation of water from the subducting crust and accompanying melting is responsible for the formation of almost all magma at subduction zones.
Answer:
The Printing Press
Explanation:
In the 15th century, an invention called the printing press enabled people to share knowledge more quickly and widely. Civilization never looked back. Knowledge is power, as the saying goes, and the invention of the mechanical movable type printing press helped disseminate knowledge wider and faster than ever before.
