Plate tectonics
This man had a hypothesis about continental drift though nobody believed him until long after his death.
Who is Alfred Wegener?
The outermost layer of earth that come in two different kinds and is mainly made from oxygen, silicon, and aluminium.
What is the crust?
This is the process in which rocks change from from one shape to another due to stress.
What is deformation?
A place where gas, ash, or melted rock comes out from the ground.
What is a volcano?
____________ are sudden movements in the ground that occur when blocks within the earth move or suddenly release energy
What is an Earthquake?
Scientists once believed that the earth was once one giant landmass combined together by all of the continents.
What is Pangaea?
An area of hot slowly flowing rock that is also located between the core and the crust.
What is the Mantle?
_________ occurs when rocks are under stress and they start to layer our horizontally on top of each other.
What is Folding?
A _________ volcano is a volcano that is no longer active.
What is a dormant volcano?
This is the area within earth along a fault at which the first motion of an earthquake occurs.
What is the Focus?
_____________ is a process in which molten rock (magma) comes out from inside the earth through cracks and forms new oceanic crust.
What is sea-floor spreading?
This area extends from below the mantle and makes up about one-third of the earth mass
What is the core?
This kind of stress pushes rocks in a parallel but opposite direction and is common along strike-slip faults.
What is shear stress?
_____________ is the resistance of a liquid material to flow it can also determine the explosiveness of an eruption and the shapes of volcanic mountains.
What is viscosity?
This place is located right above the focus on the earth's surface.
What is the Epicenter?
This is the place where old sea floor gets deposited and also where underwater canyons can form, they can also support Alfred Wegener's hypothesis of continental movement.
What are ocean tenches?
____________, ______________, ______________ are the compositional layers of the earth.
What is the core, mantle, and the crust?
This kind of stress pulls and stretches rocks part and is common along normal faults
What is tension?
This kind of eruption happens when lava flows from giant cracks in earth's surface or fissure and onto earth's surface.
What is a Fissure Eruption?
_______________ is the process in which rocks return to its original shape after undergoing deformation which is rocks changing shape due to stress.
What is Elastic Rebound?
This layer of the earth is divided into many different little pieces of land called tectonic plates.
What is the lithosphere?
The ____________, ______________, _____________, ______________, _____________ are the five physical layers of the earth.
What is the lithosphere, asthenosphere, mesosphere, outer core, and inner core?
This kind of stress squeezes and pushes rocks together and is common along reverse faults.
What is compression?
This is a location that is used to describe numerous amount of explosions on convergent boundaries which also surrounds the pacific ocean many earthquakes and volcano eruptions tends to happen a lot in that area.
What is The Ring of Fire?
An underwater earthquake that can cause vertical movement along the sea floor and can travel up to about eight hundred kilometers per hour.
What is a Tsunami?
