Answer:
Volcanic degassing of volatiles, including water vapour, occurred during the early stages of crustal formation and gave rise to the atmosphere. When the surface of Earth had cooled to below 100 °C (212 °F), the hot water vapour in the atmosphere would have condensed to form the early oceans.
Explanation:
The following tests can determine the mineral in a rock specimen:
1. How does the rock crumble or split under pressure?
2. What is the texture of the rock?
3. Observing it under a magnifying lens.
4. Determine the color of the rock
Test 1 and 3 determines if the rock is granular and the types of grains in the rock. Test 3 also determines if the rock has layers hence sedimentary rock.
Determining whether color of the rock is dark or light also helps identify the mineral and type of rock.

Answer:
cartilaginous joints
Explanation:
The joint system is formed by the joints, which can be defined as the joining region between two or more bones. All bones in the body except the hyoid bone are articulated with at least one other bone. There are several types of joints, among them, the cartilage joints, those that have cartilage between the bones. If this cartilage is hyaline, the joint is called synchondroses; if the cartilage is fibrous, the joint is called symphyses.
The joints are responsible for holding the bones together and allowing the skeleton to move.
