What is the major difference between continental drift and plate tectonics quizlet?
What are the differences between Continental Drift and Plate Tectonics? Continental drift believes that the continents moved because the magnetism of the sea floor. Plate tectonics believes that the lithosphere & the asthenosphere of the continents caused them to move.
What is the major difference between the continental drift theory and the theory of plate tectonics in terms of what makes up the earth’s crust?
The theory of continental drift suggests that all the land masses on earth were once part of one supercontinent. Plate tectonics is the ability to measure the movement of land masses.
How are plate tectonics and continental drift similar?
Plate tectonics is Wegener theory of continental drift reworked. The force needed to move the continents is proposed to be convection currents in the mantle. Geologist have a much better understanding the structure of the earth, in terms of the crust, and mantle than was available in Wegener's time.
What causes continental drift and plate tectonics?
Wegener suggested that perhaps the rotation of the Earth caused the continents to shift towards and apart from each other. (It doesn't.) Today, we know that the continents rest on massive slabs of rock called tectonic plates. The plates are always moving and interacting in a process called plate tectonics.
What is the difference between continents and tectonic plates?
The continents are embedded in the plates. Many continents occur in the middles of plates, not at their boundaries or edges. Plates also underlie the Earth's oceans. A single plate often includes both continental and oceanic regions.

What is plate tectonics and continental drift?
Plate tectonics is the theory that Earth's land masses are in constant motion. The realization that Earth's land masses move was first proposed by Alfred Wegener, which he called continental drift.
What is the similarities between continental drift and plate tectonics?
The similarities would be the movement and they are both apart of one large theory. The difference between continental drift and plate tectonics is that the theory of continental drift states that the world was made up of a single continent.
What causes plate tectonics?
Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth's crust.
Why was the continental drift change to plate tectonics?
Wegener suggested that perhaps the rotation of the Earth caused the continents to shift towards and apart from each other. (It doesn't.) Today, we know that the continents rest on massive slabs of rock called tectonic plates. The plates are always moving and interacting in a process called plate tectonics.

What is the theory of continental drift?
The theory of continental drift is most associated with the scientist Alfred Wegener. In the early 20th century, Wegener published a paper explaining his theory that the continental landmasses were “drifting” across the Earth, sometimes plowing through oceans and into each other.
What else does continental drift cause?
These tectonic plates rest upon the convecting mantle, which causes them to move. The movements of these plates can account for noticeable geologic events such as earthquakes, volcanic eruptions, and more subtle yet sublime events, like the building of mountains.
How are continents and tectonic plates related?
Every continent has one or more tectonic plate underneath them. Therefore, they are related because these plates under the continents can change the landforms of that landmass.
What is the theory of plate tectonics?
Plate tectonics is the theory that Earth's outer shell is divided into large slabs of solid rock, called “plates,” that glide over Earth's mantle, the rocky inner layer above Earth's core. Earth's solid outer layer, which includes the crust and the uppermost mantle, is called the lithosphere.
How are plate tectonics related to continental drift?
Plate tectonics is the theory that Earth's land masses are in constant motion. The realization that Earth's land masses move was first proposed by Alfred Wegener, which he called continental drift.

Do plate tectonics cause continental drift?
Continental drift over millions of years was caused by plate tectonics. And plate tectonics also explained how the movement of the plates create volcanoes and earthquakes, and how the collision between continents gave rise to huge mountain ranges.
