We are talking about chemical reaction here. In a chemical reaction, substances that react are called reactants, and substances which are formed are called products. Atoms in the reactants break their bond, rearrange themselves and form new bonds to make the product. So no atoms are added or removed, which is called law of conservation of atoms/mass.

Answer:
Physical Weathering
Explanation:
As per the given conditions in the question, the primary effect is <u>mechanical action</u> which is also known as a <u>physical weathering</u>. During mechanical action, a rock is disintegrated into the smaller pieces. In the given statement, <u>the root of tree would grow in the crack and try to develop a strong network to get nutrients necessary for tha tree growth</u>. Thus, the <u>root would exert a pressure</u> in the crack to make more space for its growth and development (root network). This is primarily a mechanical action and an example of physical weathering.
Answer:
- Erosion and deposition (shoreline retreat)
Explanation:
Sand moves along a shoreline through hydraulic and mechanical action (friction) of the waves. During this course, two phenomenons usually occur, i.e. erosion followed by deposition.
However, sometimes when the wave action is stronger, it leads to the coastal erosion or the shoreline retreat where a land part is permanently lost and the sand is moved with the waves forming beaches.
