How do hot spots prove the tectonic plates can move?
Hot spots are located along the midocean ridge. These hot spots erupt lava over and over again causing the seafloor to spread out. This causes seafloor spreading proving the plates can move.
Hot spots move along with the plates. Since both the plates and the hot spots move, they are able to form multiple islands. This is why there are often chains of islands instead of one single island proving the plates do move.
A hot spot is stationary meaning it stays in one spot. Because the plates continuously move, islands can form close to one another as the plates move. Hawaii is a great example! If the plates did not move, Hawaii would be one large landmass today instead of several islands proving the plates do move.
Hot spots are stationary meaning they stay in one spot. Multiple hot spots are responsible for forming the Hawaiian islands. The islands are each over a different hot spot. The islands are continuing to grow since the plates above the hot spots are stationary proving the plates can move.

A science teacher shows his students an image of a volcanic mountain range and informs them it was created by the movement of Earth’s Tectonic plates. He asked his students to explain how this occurred. Which explanation is BEST?
The oceanic crust converged with the oceanic crust. Both pieces of oceanic crust subducted, forcing lava upward towards the surface of the Earth causing a volcanic eruption which created the mountains.
The continental crust converged with the continental crust. Neither piece of continental crust subducted so lava was forced upward towards the surface of the Earth causing a volcanic eruption which created the mountains.
The oceanic plate converged with the continental crust. The more dense, continental crust sank below the less dense oceanic crust causing magma to rise up through a weak spot in Earth’s crust to create volcanic mountains.
