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.
What else can I help you with?
What theory states that plates move around on the athenosphere?
The theory that states that plates move around on the asthenosphere is called plate tectonics. This theory explains the movement of the Earth's lithosphere into different plates and their interactions at plate boundaries due to the convective currents in the asthenosphere beneath them.
Which theory describes the motion of earth's crust on its mantle?
plate tectonics=D
What did the theory of plate tectonics replace?
The theory of plate tectonics replaced the older theory of continental drift. It provided a more comprehensive explanation for the movement of Earth's lithospheric plates and the processes that shape our planet's surface.
What geological theory states that pieces of the Earth's lithosphere are in constant slow motion?
The theory of plate tectonics states that pieces of the Earth's lithosphere, called tectonic plates, are in constant slow motion, driven by processes such as seafloor spreading, subduction, and continental drift. These movements can result in events like earthquakes, volcanic eruptions, and mountain formation.
What is the name of the person who is normally associated with the plate tectonics theory?
Alfred Wegener is the person normally associated with the plate tectonics theory. He proposed the theory of continental drift in the early 20th century, which later evolved into the modern understanding 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 theory states that earth's surface is broken into separate plated?
Plate tectonics
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 does the theory of plate tectonics affirm?
The theory of plate tectonics explains large scale motion of the earth's lithosphere.
The theory of plate tectonics affirms what?
The theory of plate tectonics explains large scale motion of the earth's lithosphere.
Why is plate tectonics theory thought to be a unifying theory?
Plate tectonics is considered to be a unifying theory because a consensus finds it to be true. Most scientists believe the plate tectonics cause volcanoes and earthquakes.
How can you define plate tectonics not plate tectonics theory?
But plate tectonics is the theory which suggests that the Earth's crust is made up of solid plates moving relative to each other. Plate tectonics and the plate tectonics theory aren't really two separate things. However plates are pieces of the Earth's crust which are moving.
What is another name for the plate tectonic theory?
The Theory of Plate Tectonics?
What theory states that plates move around on the athenosphere?
The theory that states that plates move around on the asthenosphere is called plate tectonics. This theory explains the movement of the Earth's lithosphere into different plates and their interactions at plate boundaries due to the convective currents in the asthenosphere beneath them.
