First and foremost we have measured the rate of continental drift using highly accurate GPS systems. The Indian subcontinent is gradually moving north, and the Americas continue drifting west at an inch or so per year.
Second, the Hawaiian and Marshall Island seamounts drift off to the west of Hawaii, indicating sea floor spreading, as does paleomagnetic striping along the mid oceanic trenches. Of course, you want to know about continental drift, not sea floor spreading (which is related). The existence of convection currents within earth's molton mantle has been fairly well confirmed. More evidence consists of matching rock outcrops along the western coast of Africa and the eastern coast of south America, and elsewhere. One more piece of evidence consists of similar fossils on both continents dating back some 130 to 200 million years or so.

Which theory describes the motion of earth's crust on its mantle?
plate tectonics=D
What theory states that plates move around on the athenosphere?
the crust cracks and magma fills in the space
What did the theory of plate tectonics replace?
The theory of plate tectonics replaced the theory of sea floor spreading.
What geological theory states that pieces of the Earth's lithosphere are in constant slow motion?
The geological theory that states that pieces of earths crust are in constant slow motion is called the Continental Drift Theory. This theory also considers Pangea, the way the continents were before the drift.
What theory explains the movement of pieces of earths surface?
theory of plate tectonics
What are some landforms in California that support the plate tectonics theory?
hups, bzzr

What is a creationist theory for plate tectonics?
Creationist theory and plate tectonics do not disagree in any way.
How do observations of earthquakes and volcanic activity support theory of plate tectonics?
Observations of earthquakes and volcanic activity support the theory of plate tectonics because they both occur on boundaries. Boundaries are where plates meet and either converge, diverge or transform.
What Is the theory that the earths lithosphere is divided into tectonic plates that move around on top of the asthenosphere?
A theory that says the lithosphere is divided into plates that move around on top of the asthenosphere is called '' plate tectonics''
What is The theory that describes large scales movements of the lithosphere called?
Plate tectonics
What theory states that earth's surface is broken into separate plated?
Plate tectonics
What are some landforms that support the plate tectonics theory?
Earthquakes, volcanoes, canyons, mid-ocean ridges, mountain ranges and so on and the results of plate tectonics.
What geological theory states that pieces of the Earth's lithosphere are in constant slow motion?
The geological theory that states that pieces of earths crust are in constant slow motion is called the Continental Drift Theory. This theory also considers Pangea, the way the continents were before the drift.
What are the huge sections of the earth's crust that move called?
plate tectonics
