Layers
This layer of the earth is the thickest?
What is the mantle?
Names of features that would appear at Divergent Boundaries.
What is a mid- ocean ridge and/or a rift valley?
Direction plates move in this type of boundary
What is toward each other?
Direction in which plates move in this kind of boundary.
What is past each other in opposite directions or side to side?
Earth's inner core is made of this:
What is a solid core of iron?
The top part of the mantle and the crust above it.
What is the (Earth's) lithosphere?
Direction of movement of plates in this kind of boundary
What is away from each other?
Names of the 3 types of Convergent boundaries:
What is Continental-Continental, Continental-Oceanic, and Oceanic-Oceanic?
Names of features found at transform boundaries?
What are earthquakes and faults?
Earth's outermost and thinnest layer:
What is the crust?
When looking at a cross-section of rock layers, this layer is where the OLDEST fossils be found?
What is the bottom layer or first layer?
Thing that is happening to crust in Divergent boundaries:
What is being created?
Features found at Continental- Continental Convergent boundaries:
What are folded or faulted mountain ranges?
Well known example of transform boundaries in the U.S.?
What is the San Andreas Fault?
Earth's magnetic field results from movements in this layer:
What is the outer core?
This soil layer has the greatest amount of decayed material:
What is the organic layer/top layer/Horizon O?
An example of a divergent boundary
What is a mid-ocean ridge? Or, what is a rift valley?
Features found at the Continental-Oceanic Convergent boundaries
What are trenches and volcanic mountains?
Names of plates sliding past each other in San Andreas Fault
What are the Pacific and North American plaates?
Most geologists think that the movement of Earth's plates is caused by this:
What are convection currents in the mantle?
This is how scientists learn about the mantle and core of the Earth:
What is seismic activity or by studying the material that oozes up from cracks in the earth?
Reason plates separate
What is magma pushing through the crack of the two plates?
Feature found at Oceanic-Oceanic Convergent boundaries:
What is are trenches and volcanic island arcs?
Reason earthquakes occur
What is jerking and shaking of plates as they slide past each other? :-)
The Earth's layers in order from innermost to outermost:
What is inner core, outer core, mantle, and crust?
