Answer:

A. Highly viscous and associated with violent eruptions

Explanation:

Most silica rich magma have high viscosity and huge amount of trapped gases within them. As they continue to upwell and expand, the gases causes violent eruptions near Volcanoes. Most granitic/rhyolitic magma are silica rich.

Answer: Option (A)

Explanation: Silica rich magma are those in which the magma has more than 65 % of silica content. The higher the silica content, the higher is its viscosity i.e viscosity of a magma is directly proportional to the silica content of magma.

This highly viscous magma inside the volcanoes moves sluggishly and mostly gets concentrated in the vents and seals them. With time, when the pressure exerted by the magma is too high, it creates violent eruptions through the vents.

Thus, the correct answer is option (A).

Match the lithification processes.
Varvara68 [4.7K]

Answer:

ReCrystallization

Contact pressure causing grains to "grow" together.

It's a metamorphic process used to rearrange the atoms of the minerals in order to modify them in to the required form under the specific temperature and pressure. For example conversion of limestone into marble.

<em>Cementation:</em>

Precipitation of bonding agents between grains.

Cementation is the process in which the minerals in the form of fluid fills in spaces between the grains and binds them together upon crystallizing.

<em>Compaction:</em>

Increase in density due to weight of overburden.

Compaction as it's name indicate is the compaction of the sediments due to the heavy weight of the rocks which reduce their size and increase their density.
