The answer is B, sodium is an element.
Speed is the rate at which something goes, and velocity is the average acceleration, which means a car can go slow for a bit, and fast for a bit, and have a velocity of medium. Also, speed is much easier to measure.
That would be the proton. The number of protons in the nucleus determine which element it is and its properties.
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.
