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.
Which type of scientific statement is this?
Hypothesis
Theory
Law
Prediction - correct answer Law
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.
