mid-ocean ridge

• an undersea valley that represents one of the deepest parts of the ocean

• the process by which molten material adds new oceanic crust to the ocean floor

• an undersea mountain

  chain where new ocean floor is produced; a divergent plate boundary under the ocean

• a plate boundary where two plates move

  toward each other

stress

• stress that stretches rock so that it becomes thinner in the middle

• a break in Earth's crust along which rocks move

• stress that squeezes rock until it folds or breaks

• a force that acts on rock to change its shape or volume

sea-floor spreading

• an undersea mountain chain where new ocean floor is produced; a divergent plate boundary under the ocean

• the process by which oceanic crust sinks beneath a deep ocean trench and back into the mantle at a convergent plate boundary

• the process by which molten material adds new oceanic crust to the ocean floor

• an undersea valley that represents one or the deepest parts of the ocean

hypothesis

• an idea that has been studied and investigated and is supported by a vast and diverse array of evidence

• the size or extent to which something occurs

• an evidence-based idea that can be tested by experimentation or investigation

• describes something that is made of a mixture of different parts or elements
