B:Oxygen and silicon
Explanation:
Most minerals on the earth's surface contains oxygen and silicon. Silicon and oxygen are the most abundant elements we find in the rock minerals on the earth surface.
- Silicon and oxygen forms the SiO₄⁻ tetrahedron through which several minerals are formed.
- These minerals built on the network of the tetrahedron are referred to as silicates.
- Several silicate minerals are known:

Answer:
Texture Gradient
Explanation:
Texture Gradient -
It refers to the disrupted pattern on any uniform surface , is referred to as the texture gradient .
The pattern is somewhat very uniform in nature , i.e. , is constant over a particular area .
The three types of texture gradient are-
- perspective ,
- density and
- distortion of texture elements .
Hence , from the given information of the question ,
The correct answer is texture gradient .
