Answer:
Atoms form chemical bonds to make their outer electron shells more stable. ... An ionic bond, where one atom essentially donates an electron to another, forms when one atom becomes stable by losing its outer electrons and the other atoms become stable (usually by filling its valence shell) by gaining the electrons.

Answer:
A. Rock fragments are layered and pressurized over time.
Explanation:
Sedimentary rocks are derived from pre-existing rocks that have been subjected to agents of denudation, weathered, transported and deposited within a basin.
In the basin, the sediments are accumulated in their final resting position.
- Sediments are accumulated as layers on top of one another.
- The pressure of the sediment on top of another forces out water and presses the layers into sheets.
- Over time, the compression leads to lithification of the rock.
- During lithification, compaction and cementation occurs.
In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.
