From the above statement, John can infer that the rock underwent metamorphism and also is not altered by heat or pressure.
<u>Explanation</u>:
- Metamorphic rock is an igneous sedimentary rock and although when put through heat the rock becomes hot but does not alter its shape or melt. If the rock melts then it is only an igneous rock and not a sedimentary one.
- During metamorphism, the chemical and the mineral content of prolith are changed due to changes in the environment based on physical and chemical conditions.
- Even though the rocks remain solid, fluid is present between the macroscopic spaces.
- This gives "The Geologist" accurate information of what happens beneath the earth during the formation of mountains.
- Metamorphic rocks are like probes that go down the earth and comes back giving information of what happens underneath the surface.
When fossil fuels are burnt, CO2 is released into the air and is taken up by plants during photosynthesis to form glucose and subsequently starch.
Fossil fuels contain a large proportion of carbon atoms. When fossil fuels are burnt, these carbon atoms are released as carbon dioxide and escape to the atmosphere as atmospheric CO2 in air.
Recall that plants take up the CO2 in air during the process of photosynthesis. This CO2 becomes combined with water in the presence of sunlight to form glucose.
This glucose is converted to starch and stored in plant tissues. This is how the carbon atom inside a fossil fuel becomes a carbon atom inside a plant.

<u>Answer: </u>The chemical symbol of the element is Sulfur.
<u>Explanation:</u>
The element which is present in third period of the periodic table having four 3p electrons is Sulfur. Sulfur is the 16th element of the periodic table which has 6 valance electrons.
The electronic configuration of this element is: ![[Ne]3s^23p^4](https://tex.z-dn.net/?f=%5BNe%5D3s%5E23p%5E4)
This element is considered as a non-metal because it will accept electrons in order to attain stable electronic configuration.
Hence, the chemical symbol of the element is Sulfur.
