◉ Sir Isaac Newton discovered that the force of gravity between two
masses increases if the masses increase, and decreases if the
distance between the masses increases. No experiments have ever
contradicted this relationship.

◉ The well-accepted scientific explanation for many characteristics
of Earth's crust states that the crust is broken into several large
plates. These plates move slowly over the mantle below because of
convection and other processes. Earthquakes and volcanoes are
most common at places where the plates interact. Evidence from
physics, chemistry, and geology supports this explanation.
Which type of scientific idea is this explanation an example of?
