Name and describe the feature of the ocean floor shown at A. Mid ocean range, a mountain on the sea floor sometimes hidden under hundreds of meters of water. Describe the process shown occurring at B, and explain what results from this. Sea floor spreading, adds new material to the seafloor.
The Theory of Plate Tectonics Worksheet Objective: Gather evidence to explain the theory of plate tectonics. Materials: Work in pairs sharing one computer with Internet access.
What is the evidence for sea-floor spreading? Several types of evidence supported Hess's theory of sea-floor spreading: eruptions of molten material, magnetic stripes in the rock of the ocean floor, and the ages of the rocks themselves.
29 Νοε 2023 · Seafloor spreading is a geologic process in which tectonic plates —large slabs of Earth's lithosphere —split apart from each other. Seafloor spreading and other tectonic activity processes are the result of mantle convection. Mantle convection is the slow, churning motion of Earth’s mantle.
Study with Quizlet and memorize flashcards containing terms like Sea-Floor Spreading, System that uses sound waves to calculate the distance to an object, Deep faulted structure found along a divergent boundary and more.
The pattern in the ages of the rocks across the Mid-Atlantic Ridge is used as evidence of sea-floor spreading. In this activity, you will observe the pattern and learn to calculate the rate of sea floor spreading. The diagram on the next page represents a section of the ocean floor in the North Atlantic.
Explain the evidence that is used to support the theory of plate tectonics. How does seafloor spreading causes Earth's plates to move? How does paleomagnetism provide evidence for seafloor spreading?
