What Best Describes the Theory of Plate Tectonics

The theory of plate tectonics state that the pieces of Earths lithosphere are in slow constant motion. The plates act like a hard and rigid shell compared to Earths mantle.

Sections of Earth s continents are in slow constant movement.

. Plate tectonics is the modern version of continental drift. Sections of Earth that shift are part of Earth s asthenosphere. Plate tectonic theory had its beginnings in 1915 when Alfred Wegener proposed his theory of continental drift Wegener proposed that the continents plowed through crust of ocean basins which would explain why the outlines of many coastlines like South America and Africa look like they fit together like a puzzle.

They are also driven by molten material. Seafloor and continents move around on Earths surface but what is actually moving. These pieces are called tectonic plates and they come in various shapes and sizes.

The plates consist of two principal types of material oceanic crust and continental crust. Plate boundaries are the edges where two plates meet. An area of low land with steep walls formed at divergent boundaries.

In plate tectonics Earths outermost layer or lithosphere. Parts of the ocean floor move as they are carried by rift valleys. Plate tectonics is the theory that states that Earths outer shell is divided into several plates that glide over the mantle.

Continents move over the ocean floor. This happens when two oceanic plates move apart. The reason why Earths.

The theory that pieces of the lithosphere are constantly moving due to convection currents in Earths mantle. B Sections of Earth that shift are part of Earths asthenosphere. Theory of Plate Tectonics.

The tectonic plates can consist predominantly of continental crust or predominantly of oceanic crust and there isnt a single plate that is exclusively made out just from one type of crust. A new crust is formed over the ocean floor. A Plates sometimes move closer to one another.

Which statement best describes the theory of plate tectonics. When the concept of seafloor spreading came along scientists recognized that it was the mechanism to explain how continents could move around Earths surface. Theory of Plate Tectonics Earths Tectonic Plates.

Like the scientists before us we will now merge the ideas of continental drift and seafloor spreading into the theory of plate tectonics. D Parts of the ocean floor move as they are carried by rift valleys. This strong outer layer is called the lithosphere.

Fossils are formed everywhere. The statement that best describes the theory of plate tectonics is the one that says that sections of Earths continents are in slow constant movement. Plate tectonics has revolutionized the way we view large features on the surface of the Earth.

Earths crust is broken up and divided into numerous pieces. Earths surface is broken to many pieces. Which statement best describes the theory of plate tectonics.

AnswerPlate tectonics theory basically states the earth is made up of constantly moving massive plates of rockExplanation. Plate tectonics is a geological theory developed to explain the phenomenon of continental drift that is the continents of the earth are not invariably positioned on the surface of. Which statement best describes the theory of plate tectonics.

C Sections of Earths continents are in slow constant movement. Plates sometimes move closer to one another. The molten material hardens and becomes cooler and then creates the oceanic crust.

Which of the following best describes the plate tectonic theory. The theory which solidified in the 1960s transformed the earth sciences by explaining many phenomena including mountain building events volcanoes and earthquakes. The theory of plate tectonics states that pieces of Earths lithosphere are in slow constant motion developed due to convection currents in the mantleThese plates move over the asthenosphere the molten upper portion of the mantle.

Sections of Earths continents are in slow constant movement. The downward movement of one. Plate tectonics is a scientific theory that explains how major landforms are created as a result of Earths subterranean movements.

Earths internal processes were previously thought to operate in a vertical fashion with continents oceans and mountain ranges bobbing up and down without much sideways movement.
