What evidence is there to suggest that the earth is composed of tectonic plates move?
Evidence for the movement of tectonic plates includes the alignment of geological features, such as mountain ranges and ocean ridges, which often match up across continents. The distribution of earthquakes and volcanic activity is concentrated along plate boundaries, indicating their dynamic nature. Additionally, the study of sonar mapping and GPS measurements shows the gradual movement of plates over time. Paleomagnetic data also reveals changes in the Earth's magnetic field recorded in rocks, supporting the theory of plate tectonics.

What was discovered that led to the knowledge that tectonic plates exist?
The discovery of seafloor spreading provided evidence for the existence of tectonic plates. This process involves the movement of oceanic crust away from mid-ocean ridges, indicating that the Earth's lithosphere is composed of separate plates that are in motion. This discovery revolutionized our understanding of plate tectonics.
How many tectonic plates are composed of only continental crust?
Some geologists believe there are no tectonic plates composed solely of continental crust, as plates typically consist of both continental and oceanic crust. The concept of a plate composed entirely of continental crust is not widely accepted in the field of plate tectonics.
What semi liquid layer does tectonic plates float on?
Tectonic plates float on the asthenosphere, which is a semi-liquid layer of the Earth's mantle. This layer is composed of partially molten rock that allows for the movement of the overlying tectonic plates. The asthenosphere's properties enable the plates to shift and interact, leading to geological phenomena such as earthquakes and volcanic activity.
Where are tectonic plates located?
Tectonic plates are located within the Earth's lithosphere, which is the outermost layer of the Earth. These plates float on top of the semi-fluid asthenosphere beneath them. The movement of these plates is responsible for various geological phenomena like earthquakes, volcanic activity, and mountain building.
What are the large thin plates that move relative to one another on the outer surface of earth called?
They are called tectonic or lithospheric plates.
What are most tectonic plates composed of?
Tectonic plates are composed of both oceanic and continental crust. Oceanic plates are predominantly made of basaltic rock, while continental plates are primarily composed of granitic rock. The Earth's lithosphere, which includes the tectonic plates, is made up of these crustal rocks.
Are tectonic plates composed of continental and oceanic crust?
Yesshhh :)
How sea floor spreading provide evidence for tectonic plates?
by the plate tectonic and the ocean bridges
What evidence can be provided to support the claim that Pangaea did not exist?
The evidence that supports the claim that Pangaea did not exist includes the distribution of fossils, rock formations, and the movement of tectonic plates. Fossils of similar species found on different continents suggest that they were once connected. Additionally, the alignment of rock formations and the movement of tectonic plates provide further evidence that the continents were not always together as one supercontinent.
What was discovered that led to the knowledge that tectonic plates exist?

This discovery revolutionized our understanding of plate tectonics.
What provides the most evidence for the theory of plates tectonic?
The spreading of the sea floor.
Are plates any where else but under the sea?
Yes. All of Earth's crust, both on land and on the seafloor, is composed of tectonic plates.
Where on earth do you see evidence that tectonic plates have collided in the past?
south america and africa .
What is composed of oceanic continental crust and upper mantle?
That would be the lithosphere which is split into tectonic plates.
Are plates composed of the crust and part of the upper mantle?
Yes, tectonic plates are composed of the Earth's crust and part of the upper mantle. The movement of these plates is responsible for various geological phenomena such as earthquakes and volcanic activity.
How many tectonic plates are composed of only continental crust?
