A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds. » Wikipedia
Explanation:
At convergent plate boundaries two plates are moving towards one another and different scenarios are in play.
Most importantly, at these margins the crust is being destroyed.
- At continental - continental crust margin, there is an uplift because the density of the two crust is similar and lesser than that of the mantle below.
- At continental - oceanic crust margin, subduction zones are found where the denser oceanic crust sinks beneath into the mantle.
- This is also the case with ocean - ocean convergence zone.
Some of the features found at this margin include, oceanic trenches, accretionary wedges, volcanic islands, earthquakes
The first step of the scientific method would be Observations.
