Question

Arrange unknown specimens Unknown - 3, Unknown - 4, and Unknown - 7 in order of rapid to slow cooling. Explain your answer. (15 points)

Answer 1

Volcano:

The volcano is the release of the materials having high temperature,T inside the crust of the planet. As the materials present inside the crust of the earth, and when the materials comes out of the underground or lower region of the earth's layer the temperature of the different materials goes down or decreases.

The materials which comes out in the form of lava or molten rock are composed of various elements. And each element has a different temperature range.

1. Obsidian(unknown specie 3)- It is the part of the volcanic eruption, which is low on water molecules and has a high number of silica in it. As the different molecules are different molecules in it having difference in there chemical and physical properties, leads the to having low temperature for cooling down.
2. Fine grained pyroxene(Unknown specie 4)- While, the fine grained pyroxene is composed of the igneous form of rocks, having the fine number of quartz, field spar, along with the traces from hornblende. The temperature required to cool down the fine grained pyroxene is more then the obsidian.
3. Fragmental Tuff(Unknown specie 7)- While the frag-mental tuff is composed of the volcanic ash. As the volcanic ash has a higher temperature for cooling it down.

Step-by-step explanation:

• Rapid cooling of the material:

The different materials or the unknown species have different properties, s they have a very unique way of dealing with the environmental factors and situations. As the different species deal with the change in environmental factors such as exposure to the outside environment, while coming out of the deepest layer i,e crust of the planet earth.
