Carbon-14 is a radioactive isotope used to date organic material. Its consistent rate of decay allows the age of an object to be determined by the proportion of carbon-14 to other carbon isotopes. This process is called radiocarbon dating. Carbon-14 is also used as a radioactive tracer for medical tests.
Answer:
The solidifying/cooling and crystallizing of magma causes igneous rocks to form.
Answer: option 2.

Explanation:
Answer:
A.
Liquid
B.
Gas
C.
Gas
D.
Solid
E.
Liquid.
Explanation:
Solids have definite shape and volume and vibrate around a fixed position. Its relative intermolecular forces are very strong which holds its particles in a fixed position.
Liquids takes the shape of the container, that is no definite shape, has fixed volume and its particles move freely but are still attached to each other due to its mildly strong intermolecular forces.
Gases has no shape nor volume but it is highly compressible while its particles move freely in random paths.
