Section 5 Flashcards
What is the definition of scientific theory?
A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment.
What is the definition of plate?
A section of the lithosphere that slowly moves over the asthenosphere, carrying pieces of continental and oceanic crust.
What is the definition of plate tectonics?
a theory explaining the structure of the earth’s crust and many associated phenomena as resulting from the interaction of rigid lithospheric plates that move slowly over the underlying mantle.
What is the definition of fault?
a crack in the earth’s crust resulting from the displacement of one side with respect to the other.
What is the definition of divergent boundary?
In plate tectonics, a divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other.
What is the definition of Rift Valley?
a large elongated depression with steep walls formed by the downward displacement of a block of the earth’s surface between nearly parallel faults or fault systems.
What is the definition of convergent boundary?
In plate tectonics, a convergent boundary, also known as a destructive plate boundary (because of subduction), is an actively deforming region where two (or more) tectonic plates or fragments of the lithosphere move toward one another and collide.
What is the definition of transform boundary?
A transform fault or transform boundary, also known as conservative plate boundary since these faults neither create nor destroy lithosphere, is a type of fault whose relative motion is predominantly.
