What type of rock forms when heat and pressure change the structure texture or composition of sedimentary rock?

A "metamorphic" rock.


What causes sedimentary rocks to become metamorphic rocks?

Sedimentary rock can become metamorphic rock under intense heat and pressure. The heat and pressure do not change the rock's chemical composition, but do change its physical properties like hardness, texture, and structure.


Why are some metamorphic rocks foliated but others lack folitation?

Nonfoliated metamorphic rocks such as marble and quartzite derived their metamorphism more from heat than from directional pressure. Foliations form at right angles to intense directional pressures. Nonfoliated metamorphic rocks like quartzite and marble are mainly single-mineralic in composition, and would therefore not tend to display layering.


Will dyeing your hair change the texture?

Short answer is yes. Dying the hair involves a chemical process, which damages the hair. This causes the texture of the hair to change for a short while and it becomes dry, rough and often normally smooth hair will get knotty.


What are facts about metamorphic rock?

Metamorphic rocks are formed by pressure and heat. You can tell them apart by their texture. The 2 categories of texture are foliated or non-foliated. Foliation refers to the layering and alignment of the rocks crystals. Metamorphic rocks are also identified by looking at its mineral composition. For instance Quartzite is identified by its quartz sand grains.


What is rock that is changed by heat pressure or chemical change?

Metamorphic rocks have been changed by heat or pressure. This can be a change in size, shape, or arrangement of minerals.
