Chorea is an abnormal involuntary movement disorder, one of a group of neurological disorders called dyskinesias. The term chorea is derived from the Ancient Greek: ÏÎ¿ÏÎµÎ¯Î±, as the quick movements of the feet or hands are comparable to dancing. The term hemichorea refers to chorea of one side of the body, such as chorea of one arm but not both.
Metamorphic rocks are most likely found at a site that is  deep under ground. Metamorphic rocks are formed by other materials  under great amounts of pressure. This pressureâ¦ is caused by plate  collisions in the lithosphere.
In order to form magma, what must happen to sedimentary, metamorphic or igneous rocks? For weathering & erosion to occur, what process will the rock usually go through first or at the same time? Can sedimentary rock form directly from metamorphic rock? Explain your answer. All rocks follow the same pathway through the rock cycle is a false statement. Why? How does granite (igneous) change into sandstone (sedimentary)? Define igneous rocks.
