Because metamorphic rock is smaller than brick
A texture know as foliation is common in metamorphic rock and garnets are more commonly found in metamorphic rock than other rock types of the crust.
how is metamorphic rock different than intrusive rock
Igneous rock can change into sedimentary rock or into metamorphic rock. Sedimentary rock can change into metamorphic rock or into igneous rock. Metamorphic rock can change into igneous or sedimentary rock.
Brick is baked mud, and as such, can be considered to be sedimentary.
If the rock melts the resulting rock type would be igneous rather than metamorphic.
A pencil contains graphite, this is an allotrope of carbon. As such it is an elemental mineral rather than a metamorphic rock!
By a process of melting and re-solidification of the melt produced..
Not exactly. Some metamorphic rocks have foliation, which can appear similar to the layers of sedimentary rock. Foliation develops from mineral grains being oriented by pressure, rather than the deposition of layers.
if rock melts it will form magma, which leads to the formation of igneous rocks
Yes.
If by particles you mean the size of the crystals, then the crystals in metamorphic rock are often larger than in the sedimentary rock. High heat and pressure can cause the minerals to recrystallize. This would be the case in the metamorphosis of limestone (sedimentary) to marble (metamorphic).
actually, it truly depends on the type of rock the metamorphic rock formed from. in other words, if it formed from a rock that held basalt in it, the rock has basalt in it. remember that a metamorphic rock can be formed by more than two different types of rock (such as metamorphic quartz, slate, "fool's gold", plus granite). it does not matter which class the metamorphic rock formed from (but if a m. rock such as m. quartz, there is more likely a chance of finding a trace of basalt), as long as it formed from two different class of rock (this does not always apply, for there can be a metamorphic rock made from two or more metamorphic rocks). i would get into geodes...... but that's another answer. :)
