A is NOT an explanation , but a statement that describes a scientific phenomena , but does NOT explain why it happens . A theory become a law . They have mapped out the ocean floor . What they found is that it is not . On the bottom of the ocean they found a system . A ridge is a in the Earth . The ridge shape is not a . The ridge shape follows the . Ridges are underwater . They are not just mountains . Ridges release when they erupt . The ocean floor is considered to be geologically . The continents are compared to the ocean floor . Ridges are pulled apart by convection currents moving in the direction from one another . At ridges seafloor is . The you travel from a ridge the older the seafloor becomes . This is because seafloor is created at the ridge and then gets pushed out like a by the convection currents underneath the lithosphere . This process is known as . In the Theory of Plate Tectonics the Earth is . These sections are very large . They are than the size of the continents . These sections of the cracked Earth's lithosphere are called . These cracked sections move around the planet . The spot where the two plates meet is a crack in the Earth . Where two plates meet it is called a . Two plates that pull away from one another are called boundaries . Two plates that collide are called boundaries . And , two plates that slide past one another are called fault boundaries . Ridges occur along divergent .
