I don't know if this question is missing some multiple choice options that go along with it, but...
One plate will subduct (go under the other plate), creating a trench or subduction zone. The other plate goes over the subducted plate, creating raised ground. This is how mountains and volcanoes are made.
Ionic and covalent bonds are intramolecular bonds, meaning that they exist inside the molecule. These bonds deal with the exchange of electrons.
Hydrogen bonds are intermolecular bonds, meaning they bond two separate molecules. These bonds deal with the attraction between hydrogen and electronegative elements such as O and F.
Covalent bond: bond in which one or more pairs of electrons are shared by two atoms. Ionic bond: bond in which one or more electrons from one atom are removed and attached to another atom, resulting in positive and negative ions which attract each other. Other types of bonds include metallic bonds and hydrogen bonding.
Ionic vs covalent
Ionic bonds form between a metal and a non-metal. In these bonds, the electrons from the metal are donated to the non-metal.
Covalent bonds form between two non-metals. In these bonds, electrons are shared between the two atoms.
Answer:
Its how you see it.
Explanation:
1.Life on Earth is based on carbon, likely because each carbon atom can form bonds with up to four other atoms simultaneously. This quality makes carbon well-suited to form the long chains of molecules that serve as the basis for life as we know it, such as proteins and DNA.
2.All life on earth <em><u>can be thought</u></em> of as "carbon-based." Just be careful about turning this around backwards. It is true that all living things contain carbon compounds... but the opposite is not true. Just because a certain material is referred to as organic does not mean it is or ever was alive.
