What is the theory proposing the movement of continents on earth's surface?
Plate tectonics (from the Late Latin tectonicus, from the Greek: τεκτονικός "pertaining to building")[1] is a scientific theory that describes the large scale motions of Earth's lithosphere. The theory builds on the concepts of continental drift, developed during the first decades of the 20th century, and accepted by the majority of the geoscientific community when the concepts of seafloor spreading were developed in the late 1950s and early 1960s.
What concepts did magnetic striping reveal to scientists about the rock on either side of a spreading ridge?
The pattern of magnetic striping on one side of the ridge was a mirror image of the striping on the other side of the ridge, indicating that the plates were moving equally in opposite directions, giving a plausible explanation for continental drift theory. Before this discovery, no evidence of a mechanism for plate tectonics existed. It was obvious after this discovery, that new crust was being created at the ridges.
What is theory of plate tectonic?
Plate tectonics (from the Late Latin tectonicus, from the Greek: τεκτονικός "pertaining to building")[1] is a scientific theory that describes the large-scale motions of Earth's lithosphere. The theory builds on the concepts of continental drift, developed during the first decades of the 20th century. It was accepted by the geoscientific community after the concepts of seafloor spreading were developed in the late 1950s and early 1960s.Tectonic plates are composed of oceanic lithosphere and thicker continental lithosphere, each topped by its own kind of crust. Along convergent boundaries, subduction carries plates into the mantle; the material lost is roughly balanced by the formation of new (oceanic) crust along divergent margins by seafloor spreading. In this way, the total surface of the globe remains the same. This prediction of plate tectonics is also referred to as the conveyor belt principle. Earlier theories (that still have some supporters) proposed gradual shrinking (contraction) or gradual expansion of the globe.
Why do you suppose plate tectonics is a theory and not a law?
For one thing many of its premises are far from uncontroversial. A minority of geologists internationally dissent from the Plate Tectonics paradigm to one degree or another. Many of the latter are loosely organized around the New Concepts in Global Tectonics Group. These geologists and geophysicists have also organized special sessions at meetings of the International Geological Congress and the European Geophysical Union, and continue to publish the New Concepts in Global Tectonics newsletter.
What concepts is part of the theory of plate tectonics?
the tectonic plate theory is....when the tectonic plates move together to make a theory
Which theory of the organization of long term memory claims that concepts are linked by experience?
spreading activating model (associative network)
What important concepts about Earth did Hutton and Lyell agree upon?
important concepts they agreed upon are because uniformitarianism combines Hutton's idea of gradual change over time with lyells observations that such changes have occurred at a constant rate and are ongoing
What is polar creep?
In the waters of the Polar Regions, it has been said that water here has high salinity (therefore also a high density) because when the seawater freezes, most of the salt stays behind in the unfrozen seawater. As this water moves, it meets up with warmer water therefore it sinks deep beneath the surface; then it travels slowly to the equator. This movement of polar water is called Polar Creep.
What is the importance of continentally?
Understanding the concepts behind continental drift is very important. This is so that scientists can track what kinds of conditions humans will be living under in years to come.
What are the advantages of chemical equations?
Well chemical equations can help us understand how a certain substance is made and what combines with what to make it using symbol and word equations .It makes more understanding of the concepts through symbols.
What are Major concepts in science for child?
It depends upon the age of the child. The fundamental concepts of the sciences are plate tectonics for geology, the big bang and stellar evolution for astronomy, the periodic table of the elements for chemistry, Newton's laws of motion for physics, and evolution for biology. Each of these should be covered in greater depth and detail each successive year of a child's elementary and secondary education.
Are Blue's Clue's videos still popular?
Blue's Clues videos are still popular amongst toddlers and younger children. Blue's Clues is a show that airs on Nickelodeon. Blue's Clues combines concepts from early childhood education with animation to help the viewers learn.
