Earth's Layers
The compositional layer that is in the exact center of the Earth.
What is the core?
What is magma?
This is the primary stress that forms folded mountains.
What is compression?
A type associated with alternating quiet (mild) and violent eruptions.
What are composite volcanoes?
This type of volcano has the steepest sides.
What is cinder cone?
Scientists divided Earth into five layers (lithosphere, asthenosphere, mesosphere, outer core, inner core) based on this.
What are physical properties?
Constant motion caused by the transfer of energy as heat.
What is convection?
A kind of fold in which the oldest rock layers are in the center of the fold.
What is anticline?
Magma when it has reached Earth's surface.
What is lava?
The type of fault where two fault blocks move past each other horizontally.
What is a strike-slip fault?
It is thinner and denser than continental crust.
What is oceanic crust?
Where two tectonic plates collide, causing subduction and/or formation of mountains and volcanoes.
What is a convergent boundary?
A fold where the rocks get older the farther away they are from the center.
Forms a volcanically active area over a mantle plume and away from plate boundaries.
What is a hot spot?
The upper fault-block that falls from tension in a normal fault.
What is the hanging wall?
The soft layer on which tectonic plates move?
What is the asthenosphere?
A process and formation that occurs at divergent plate boundaries under the world's oceans.
What is a mid-ocean ridge?
The hanging wall moves upward in this type of fault.
What is a reverse fault?
Unlike lava, it is associated with explosive eruptions.
What is pyroclastic material?
A relatively small depression around a volcano's vent.
What is a crater?
Three main layers divided based on their chemical composition.
What are the compositional layers.
What are the core, the mantle, and the crust.
Where two tectonic plates are sliding horizontally past each other.
What is a transform boundary?
What are fault block mountains?
A type of volcano made of mostly pyroclastic materials and has the steepest sides.
What is a cinder cone?
What is deformation?
