Answer:
B. intrusion of magma into fractions
Explanation:
A pluton is a type of rock that is formed when magma cools and solidifies underground, they are an intrusive igneous rock (forced into other layers of rock), usually in cracks. The three main types of pluton are bysmalith (cylindrical), lopolith (mushroom-shaped), and laccolith (blister-shaped).
Because magma is under high pressure and takes a long time to cool, it allows time for the formation of large crystals. Therefore, plutonic rocks have coarse-grained crystals that come in many different colors and sizes. A good example is granite.
<em>Considering this information we can conclude that pluton is not manmade rock, they come in different sizes (not only large) so the correct answer is B. intrusion of magma into fractions. </em>
I hope you find this information useful and interesting! Good luck!
I would Say C. Water I’m not sure but that’s my best guess
Answer: Option (A), (B), (C) and (D)
Explanation: A mineral is defined as a naturally arising, inorganic solid, that contains a precise chemical composition and defined crystal structure. Minerals combines to form rocks. A rock contains various minerals which are formed at different pressure and temperature condition. For example, olivine, quartz, gypsum and calcite.
Minerals are often classified as oxide minerals, carbonate minerals, silicate minerals, sulfate and sulfide minerals.
Thus, all the given options are a characteristics of a mineral.
Coral reefs provide an important ecosystem for life underwater, protect coastal areas by reducing the power of waves hitting the coast, and provide a crucial source of income for millions of people. Coral reefs teem with diverse life. Thousands of species can be found living on one reef.
