Earth's Layers
This person first suggested the idea that continents were once one single landmass and then broke apart and drifted.
Who was Alfred Wegener?
This is the process in which rocks change shape under stress.
What is deformation?
This is located in top of mantle plumes.
What is a hot spot?
This is a break in Earth's crust where blocks of rock move.
What is a fault?
The layer of the core that is solid.
What is the inner core?
This was the single landmass that all continents joined together as 245 million years ago.
What was Pangea?
This is the type of fault that forms when rock undergo compression.
What is a reverse fault?
This type of material consists of hot ash and bits of rock.
What is pyroclastic material?
This is the place within Earth along a fault where the first motion of an earthquake occurs.
What is the focus?
The crust that is denser and thinner than continental crust.
What is oceanic crust?
This is the process in which new oceanic crust is created on the sea floor.
What is sea-floor spreading?
This is a type of stress that occurs near normal faults and divergent boundaries.
What is tension?
What is a dormant volcano?
This is the sudden return of rock to its original shape after elastic deformation.
What is elastic rebound?
The physical layer of Earth that tectonic plates float on.
What is the asthenosphere?
This describes the big movements of Earth's lithosphere.
What is plate tectonics?
This is a type of mountain made from folding and faulting.
What are folded mountains?
This is the resistance of lava to flow.
What is viscosity?
What is a convergent boundary?
The physical layer of Earth the tectonic plates make up.
What is the lithosphere?
This is the process in which material moves in the mantle due to differences in density, and it causes tectonic plates to move.
What is mantle convection?
This type of fault usually occurs near transform boundaries and forms due to shear stress.
What is a strike-slip fault?
This is composed of many explosive volcanoes that surround the Pacific Ocean.
What is the Ring of Fire?
This is a series of extremely long waves that can travel across the ocean at speeds as high as 800 km/hr.
What is a tsunami?
