The cervical
vertebrae serve as a link between the thoracic spine-rib cage and the
head. Each thoracic
vertebrae has one pair of ribs that attaches to it laterally. <span>The vertebral column is composed of

Answer:
The word or phrase that describes slate "Foliated, igneous,metamorphic grains, arranged in parallel layers"
Explanation:
Slates are defined as the fine grained, homogeneous, metamorphic and foliated rock which are being originated from the shales of the sedimentary rock which is typically formed as a result of the clay as well as volcanic ash. The sedimental layers are maintained by the grains present in the rock. Due to the metamorphic compression the foliation occurs. slates are formed under the low grade metamorphic condition which like low temperature and pressure. Best grade slates are found in the Brazil and United kingdoms. It is found in the cliffs, underground pits etc.
