What is Plate Tectonics?

Back

Plate Tectonics is the theory that explains the movement of Earth's tectonic plates, which are large, solid pieces of Earth's crust that move due to convection currents in the magma below.

What does Newton's Law of Inertia state?

Back

Newton's Law of Inertia states that an object at rest stays at rest and an object in motion stays in motion until unbalanced forces act upon it.

Front

What is chemical potential energy?

Back

Chemical potential energy is the energy stored within the chemical bonds of a substance, which can be released or absorbed during a chemical reaction.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist a change in motion; objects at rest remain at rest, and objects in motion remain in motion.

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not cause a change in motion, while unbalanced forces do cause a change in motion.

How do convection currents affect tectonic plate movement?

Back

Convection currents in the magma below Earth's crust cause tectonic plates to move, leading to the formation of landforms.

What is the significance of Newton's 2nd Law of Motion?

Back

Newton's 2nd Law of Motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
