In my extensive experience of rock studying, I have concluded through many years of higher learning, including two PHDs and my bachelor's in psychology is that rocks make horrible friends and are in no way a substitute for a lover.

What can rock foliation tell us?
Rock foliation is the result of pressure and recrystallization when rocks undergo metamorphosis. It is the layering and parallel alignment of flattened or directionally oriented mineral crystals. Slate, phyllite, schist, and gneiss are all metamorphic rocks with foliated texture.
What can texture tell us about the history of the rock and melt?
The initial composition of the magma is dictated by the composition of the source rock and the degree of partial melting.
What is a poro us metamorphic rock?
Travertine might be called porous. Pumice might be considered metamorphic.
What 2 features of a rock help us determine how the rock was formed?
The crystalline structure and texture.
What size is a metamorphic rock?
Metamorphic rock is the result of the transformation of an existing rock type, the protolith, in a process called metamorphism, which means "change in form". The protolith is subjected to heat and pressure (temperatures greater than 150 to 200 °C and pressures of 1500 bars) causing profound physical and/or chemical change. The protolith may be sedimentary rock, igneous rock or another older metamorphic rock. Metamorphic rocks make up a large part of the Earth's crust and are classified by texture and by chemical and mineral assemblage (metamorphic facies). They may be formed simply by being deep beneath the Earth's surface, subjected to high temperatures and the great pressure of the rock layers above it. They can form from tectonic processes such as continental collisions, which cause horizontal pressure, friction and distortion. They are also formed when rock is heated up by the intrusion of hot molten rock called magma from the Earth's interior.The study of metamorphic rocks (now exposed at the Earth's surface following erosion and uplift) provides us with very valuable information about the temperatures and pressures that occur at great depths within the Earth's crust.Some examples of metamorphic rocks are gneiss, slate, marble, schist, and quartzite.

What happens each time a metamorphic rock is exposed to extreme heat and pressure?
Metamorphic Rock Metamorphism means to change form; this is exactly what metamorphic rocks do. This paper will take a look at the Earth's rock cycle to examine exactly where the metamorphic rock fits into it. It will also look at how metamorphic rocks are formed and the relationship between metamorphic rocks and igneous rock and sedimentary rocks. This paper will examine the geological characteristics and materials of metamorphic rocks, and examine some examples of metamorphic rocks and will describe mineral composition of some examples and explain its economic uses. The Rock Cycle The rock cycle helps people to understand the starting point of the igneous, sedimentary, and metamorphic rocks. In addition to explaining how each of the rocks are connected through the process. The rock cycle explains to us how the Earth assists in changing one type of rock into another type of rock. The process begins when magma, found from beneath the Earth's surface or from a volcano, cools and crystallizes. This process forms rocks called igneous rocks. When an igneous rock is exposed to weathering and erosion and compacted by the weight of the groundwater, which is otherwise known as lithification, it creates a sedimentary rock. When sedimentary rocks are buried deep within the Earth and evolve into mountains or are exposed to extreme pressure and intense heat it will then turn into the last cycle of rock, the metamorphic rock. Metamorphic rocks can even evolve from other metamorphic rocks. How Metamorphic Rocks Are Formed Within the Rock Cycle Metamorphic rocks are created when they are exposed to extreme heat, pressure, and chemicals. Rocks are usually exposed to extreme heat, pressure, and chemicals at the same time. Metamorphism occurs in one of two situations, contact metamorphism or regional metamorphism. Contact metamorphism occurs when a rocks experience a rise in temperature when it is exposed to magma. Heat is the most important source of metamorphism because... [continues]

Does schist exist outside the US?
Schist is a term for a type of metamorphic rock, and yes, it is found outside the U.S. as well as within it.
