one of the enormous slabs that make up Earth's crust and upper mantle
Earth's outermost, solid layer
the layer of Earth between the crust and the core
the forces that cause the movement of Earth's rock formations and plates
theory of plate tectonics
Earth's crust and upper mantle are broken into enormous slabs called plates or tectonic plates
places where plates interact
thin layer of crust which overlies a region called the upper mantle
What do tectonic plates consist of?
they can come together, they can move apart, and they can slide past one another
3 ways a plate can interact
earthquakes and volcanoes
What occurs along plate boundaries?
inner core, puter core, lower mantle, upper mantle and crust
What are the Earth's layers starting from the inside and moving out?
continent, ocean, or both
What can tectonic plates carry?
a super continent or "all land"
part of a continent that extends under shallow water from the ocean's edge down to a steeper slope
theory that the continents were once one landmass that had broken apart and moved to their present positions
a meteorologist that proposed the original idea of continental dirft
currents in the plasticlike mantle
What causes the plates to move across the Earth's surface?
differences in temperature in Earth's interior regions
What causes the currents in the mantle?
convergent, divergent, transform
3 types of plate boundaries
You could look at where the volcanoes and earthquakes are and predict where the tectonic plates are located.
How were the locations of earthquakes and volcanoes useful in identifying Earth's tectonic plates?
