Earth structure and plate tectonics

What are the major divisions of the Earth's interior based on chemical composition differences?

The major divisions are the crust, mantle, and core.

What are the major divisions of the Earth's interior based on physical property differences?

The major divisions are the lithosphere, asthenosphere, mesosphere, outer core, and inner core.

What is a lithospheric plate?

rigid segment of the Earth that moves and interacts with other plates.

Do all lithospheric plates move in the same direction?

No, lithospheric plates can move in different directions and at different speeds.
-Plates are in constant motion with respect to each other
-At plate boundaries, plates are...
Moving apart(Divergent), or colliding(Convergent), or sliding past each other(Transform).

What does the motion of lithospheric plates mean for the locations of continents over time?

can cause continents to drift, leading to changes in their positions over geological time.

What are the different types of plate boundaries?

divergent, convergent, and transform boundaries.

What is the Theory of Plate Tectonics?

describes the large-scale movement of the Earth's lithosphere.

What is the Theory of Plate Tectonics meant to explain?

the formation, movement, and interaction of tectonic plates and their role in geological phenomena such as earthquakes and volcanic activity.

What evidence supports the Theory of Plate Tectonics?

the fit of continental coastlines, fossil distribution, geological similarities across continents, and patterns of earthquakes and volcanoes.
