1 Age test: A child must be under a certain age depending on the particular tax benefit. 2  For the dependency exemption, the child must be younger than 19 at the end of the year. 3  However, a youth who was a student at the end of the year can be claimed as long as he or she is younger than 24.
Metamorphic rocks form when high temperatures and pressure act on a rock to alter its physical and chemical properties (metamorphism means 'to change form'). These conditions often stretch, twist and fold the rock as it cools. In metamorphic rocks some or all of the minerals in the original rock are replaced, atom by atom, to form new minerals. Types of metamorphic rocks include gneiss, quartzite, marble, schist, soapstone, and phyllite.
Best Answer: Foliation is any penetrative planar fabric present in rocks. Foliation is common to rocks affected by regional metamorphic compression typical of orogenic belts. Rocks exhibiting foliation include the typical metamorphic rock sequence of slate, phyllite, schist and gneiss.The slatey cleavage typical of slate is due to the parallel growth of microscopic mica crystals.n gneiss the foliation is more typically represented by compositional banding due to segregation of mineral phases. Foliated rock is also known as S-tectonite in sheared rock masses. Formation Mechanisms Foliation is usually formed by the preferred orientation of minerals within a rock.
