28 Απρ 2020 · Students will learn how seafloor spreading happens, how drill samples provided evidence of spreading, and the lines of evidence that support plate tectonics theory. The lesson involves engaging students with an animation and video on seafloor spreading, think-pair-share discussions, and an activity using a seafloor spreading model.
Seafloor spreading determines plate motion around a midocean ridge. Midocean ridges are always plate boundaries. Since many plates, such as the North American Plate, include continental portions attached to oceanic portions, seafloor spreading also the direction in which continents move.
15 Φεβ 2021 · Which of these also describes the current theory of plate tectonics? a. it combines elements of continental drift and seafloor spreading. b. it suggests that the lithosphere is divided into pieces, called plates.
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.
links titled, “What is the Theory of Plate Tectonics? What evidence supports the Theory of Plate Tectonics?” and “General information on plate tectonics, including images, animations and explanations.” Explore more about the theory. Read the background information and answer the following questions:
5 Φεβ 2024 · Using the online resources at the Earthquakes Living Lab, students examine information and gather evidence supporting the theory. Working in pairs, students think like engineers and connect what they understand about the theory of plate tectonics to the design of structures for earthquake-resistance.
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.
