Answer:
covalent, ionic and metallic
Explanation:
covalent bonding: A chemical bond that involves the sharing of electron pairs between atoms.
ionic bonding: When a positively charged ion forms a bond with a negatively charged ions and one atom transfers electrons to another.
metallic bonding: Is the sharing of many detached electrons between many positive ions, where the electrons act as a "glue" giving the substance a definite structure
Answer:
D. Layer B
Explanation:
The correct answer is Layer B.
The law of superposition actually states that the sedimentary rock unit is at the bottom while the the youngest rock is at the top. The principle of cross-cutting relationships states in layers of rocks, a fault or intrusion that cuts through rock layers is younger than the rocks that it cuts through.
Layer B was actually formed after Layer C. This makes Layer B younger than Layer C and closest in age to Layer C. The intrusion, Layer D is the youngest of all.
