The correct answer is B Subduction. Subduction is the process by which an oceanic plate gets dragged under another plate and is eventually destroyed in the mantle. Subduction occurs at convergent margins where two oceanic plates collide or an oceanic and Continental plate collide. Oceanic crust is made of mainly of silica and magnesium which is heavier or denser than continental crust which is composed mainly of silica and aluminium.
The subducting plate melts producing excess magma giving rise to volcanoes along these margins.
The answer would be "Rhyolite Porphyry"
It is a rock that contains
a) Orthoclase + Orthoclase phenocryst = 35 % + 15 % = 50 % = plagioclase feldspar
b) Quartz = 30%
c) Alkali fled spar = 20%
Answer:
Side = 10 cm, side = 5 cm, side = 6 cm
Explanation:
Triangle is made up of three line segment. Three line segment can form a triangle only when sum of two small line segment is more than the third line segment.
a. Side = 10 cm, side = 5 cm, side = 6 cm
5 cm + 6 cm = 11 cm > 10cm
In the first option, the sum of two small sides is more than the third size, hence it will form a triangle.
Other options do not fulfil the same criteria, so they will not form a triangle.
Hence, the correct answer is "Side = 10 cm, side = 5 cm, side = 6 cm".
