Answer:Sea Floor Spread is where the oceanic crust splits to form new crust on the earth forming ridges.
Continental slide is when tectonic plates slide past one another formed at the fault line causing earthquakes.
Transform boundaries can be explained by showing what happens after they slide almost like how after an earthquake the houses are destroyed and some have sunk into the grounds fault line.
Continental Crust is the crust of the earth that us humans and animals live on formed by divergent boundaries in the crust.

Answer:
A carbon atom can form up to four covalent bonds as one carbon atom has four valence electrons (in outermost shell). It is a fact that the number of valence electrons in a atom determines the number of covalent bonds it will form. Thus, each electron in carbon atom is used to form four covalent bonds with various four atoms.
Explanation:
A bond between a carbon and hydrogen atom is a non-polar covalent bond. The non-polar covalent bond are the bonds between two atoms which share equal number of electron(s) with each other. Example: as in case of methane, where one carbon atom shares its 4 outer valence electrons with four hydrogens by sharing equal number of electron.
In contrast, polar covalant bond are the bonds between two atoms which share unequal number of electron(s) with each other. Thus these bonds are partially ionic.
