Interfacial adhesion and surface bioactivity of anodized titanium modified with SiON and SiONP surface coatings, The statement is correct.
<h3>what is adhesion ?</h3>
Adhesion is a type of attraction between two dissimilar phases, the theory of adhesion can be up two types mechanical interlocking and physical and chemical bonding and it is a combination of three methods.
Mechanical interlocking means when two dissimilar phases interact with one another by mechanical forces, requires a rough surface where the other material can enter.
Physical bonding includes van der Waals forces and the strength is rather weak and unable to contribute that much bonding strength.
Chemical bonding consist of covalent, ionic and metallic bonding which are more stronger than physical bonds and are responsible for cohesive forces.
chemical bonding between two dissimilar materials is more complicated due to the presence of few available bonding sites.

That is very false. What about physical reactions? yeah. that's false
Answer:
Option (3)
Explanation:
Unconformity is defined as the gaps in the sequence of geological rocks. It is a geological contact that marks the boundary between the different types of rocks. In simple words, they are also known as the time of non-deposition. These unconformities have great significance in the field of geology. They are of 4 types, namely-
(1) Angular unconformity- The sedimentary rocks are initially formed and deposited in an area, after that the area is tilted and erosion takes place. Now, the new sediments are deposited forming an angle, which is commonly known as an angular unconformity.
(2) Non-conformity- When the sedimentary rocks are deposited over the igneous or metamorphic rocks, then it is known as the non-conformity.
(3) Para conformity- When the sedimentary rocks are deposited parallel to the ground surface, and absence of erosion activity, then these surface appears to be a normal (simple) bedding plane. This is known as the para conformity.
(4) Disconformity- When the sedimentary rocks are formed and undergoes erosion, then new sedimentary rocks are deposited over this and diminishes the unconformity. This forms a discontinuity.
Thus, the unconformity arises due to both erosion and lack of rock deposition.
Hence, the correct answer is option (3).
