Most minerals on earth surface contain which of the following:

a: nitrogen and oxygen
b: oxygen and silicon
c: silicon and nitogen
d: sulfur and hydrogen

Correct answer choice is :

B) Oxygen and silicon

Explanation:

Silicates comprise silicon molecules and oxygen atoms. One silicon atom is bonded to four oxygen atoms. These atoms form a tetrahedron. The silica tetrahedron is the raising block of silicate crystals. This performs silicon more or less still to more oxidation by air even up to about 900°C. After this, reaction with oxygen in the air produces silicon dioxide. At temperatures above about 1400°C, silicon responds with nitrogen, N2, in the air as well as oxygen, to make the silicon nitrides SiN and Si3N4.

The correct answer is option (B).

Explanation:

The minerals are natural occurring inorganic solids with fixed chemical compositions with constituent atoms placed in an orderly pattern.

90% of earth crust is composed of a mineral made up silicates. And these silicates are the chemical compounds made up of silicon and oxygen element. They are also known as silicon tetra-oxide with chemical formula of .

Hence, the correct answer is option (B).

when cloud cover increases then the suns ray's which provides the earth with light and warmth gets covered due to the due to the suns ray's being blocked, the temperature in that region

therefore to conclude i would like to say that,

=more the cloud cover, the lesser the
