Seafloor Spreading Drawing

Seafloor Spreading Drawing - Explain to the students what they see here is a model of the seafloor and what takes place at a mid ocean ridge. Demonstrate basic seafloor spreading with the class using the bulletin board paper and desk setup. Color the areas indicated on the two strips with crayons or colored pencils. Web the seafloor spreading definition is the geologic process that occurs at the boundary between 2 plates where molten material within the earth pushes its way up, causing the plates to move away. This idea played a pivotal role in the development of the theory of plate tectonics, which revolutionized geologic thought during the last quarter of the 20th century. Have two students slowly pull the paper away from one another (example) 4. Youngest (light colour) is along spreading centers. Web other ceep modules related to the ocean floor include: Continental drift and mantle convection are supported by bathymetric and magnetic data from the seafloor. The process is continuous because forces cause opposite sides of the midocean ridge to constantly move apart, making new room for the process to repeat.

Web seafloor spreading, theory that oceanic crust forms along submarine mountain zones and spreads out laterally away from them. Demonstrate basic seafloor spreading with the class using the bulletin board paper and desk setup. Mantle convection is the slow, churning motion of earth’s mantle. Color the areas indicated on the two strips with crayons or colored pencils.

Seafloor spreading and other tectonic activity processes are the result of mantle convection. Web seafloor spreading is a mixture different ideas and data. Seafloor spreading and other tectonic activity processes are the result of mantle convection. The process is continuous because forces cause opposite sides of the midocean ridge to constantly move apart, making new room for the process to repeat.

As A Basis For Understanding This Concept:

Web draw a labeled diagram of this type of boundary from a side view (like the large diagram on the model) showing the plates, the mantle below, and arrows to show what direction the plates are moving. And plotting the shape of the ocean floor. Thread the two strips through slit b of the larger sheet. What does the paper represent?

This Idea Played A Pivotal Role In The Development Of The Theory Of Plate Tectonics, Which Revolutionized Geologic Thought During The Last Quarter Of The 20Th Century.

Plate tectonics accounts for important features of earth's surface and major geologic events. Subduction and the “ring of fire”. Fold the paper lengthwise along the fold line “hot dog style”. The seafloor spreading hypothesis led to one of the most important paradigm shifts in the history of the earth sciences, the plate tectonics scientific revolution.
