DIA [1.3K]

Answer:

A covalent bond is present between two non-metals that share electrons in their molecular structure.

Examples of covalent bonds may be between carbon dioxide or water. And there may be three types of covalent bonds such as ionic, covalent and polar. In the first type, there is a transfer of an electron resulting in a gain for one of the atoms. In the second type, there is a sharing of electrons between the atoms.

For example: Conversation of water into water vapours.

But int he question, there is no conversion. So this option is incorrect option.

<h3>What is Sublimation?</h3>

Sublimation is the process of conversion of solid directly into the vapour phase

Since, there is no conversion of of solid into vapours. So, this option also incorrect option.

<h3>What is Mineralization? </h3>

Mineralization is defined as the process through which chemicals which is present in organic matter are decomposed or oxidized easily in the available forms to plants.

As there is no decomposition of minerals. So, this is also incorrect option.

<h3>What is Percolation? </h3>

Percolation is defined as the process in which liquid slowly allow to pass through a filter.

So, this is correct option.

Thus, we concluded that the water moves into the lithosphere through openings in the rock or soil. This process is called percolation.
