Answer:
A.
Explanation:
Shale is a sedimentary rock that is often associated with oil deposits. This is due in part to the tiny and very fine grains that make up shale. As the sediments are compacted, organic matter is trapped by the particles of clay and silt.
Later, as sedimentation continues and the layers are buried farther underground, the heat and pressure convert some of the organic material into oil. While much of the gas escapes the porous shales, some also remains trapped in the rock layer.
<span>The question is asking us which country had Fiji been ceded to by the late 19th century. If you look at Fiji's flag, you will see Union Jack, so it already suggests that it used to be a British colony. In fact, it became a British colony in 1874 and remained subjugated to the UK until 1970, when it achieved independence - so the answer is the United Kingdom of Great Britain and Ireland (as it was known then)</span>
Answer:
<u>There are a total six crystal system like triclinic, monoclinic, tetragonal, hexagonal, orthorhombic and cubic</u>.
Explanation:
- The crystal forms of the crystal family refer to several classes of crystals that are informally formed by the grouping of crystal and being divided based on sources.
- The crystal; system that corresponds to space groups is given a lattice system giving them a 32 point scale.
- These points are assigned to the trigonal crystal system which consists of all the above 6 system forms of crystals.
- Their name is given by Whittaker who formed these crystal structures as protein structures
Because humans have a lot more wonders and information than physicals
