Tectonic Plate
The outer layers of Earth are divided into these
What is lithosphere and asthenosphere
The location where two plates meet is called
What is a plate boundary
While the movement of tectonic plates is usually slow—typically just a few centimeters per year—plate tectonics are linked to several kinds of natural disasters such as
What is earthquakes
Earthquakes trace the path of the downward-moving plate as it descends into asthenosphere, this forms, and as the subducted plate is heated it releases volatiles.
What is a trench
According to many authors, plate motion is driven by the higher elevation of plates at
What is ocean ridges.
In terms of heat transfer, the asthenosphere transfers heat by this
What is convection
While the movement of tectonic plates is usually slow—typically just a few centimeters per year—plate tectonics are linked to several kinds of natural disasters such as
What is volcanos
Earthquakes trace the path of the downward-moving plate as it descends into asthenosphere, this forms, and as the subducted plate is heated it releases this
What is volatiles
This gravitational force is regarded as a secondary force and is often referred to as
What is ridge push
Lithosphere is described as
What is cooler and rigid
In terms of heat transfer, the lithosphere loses heat by this
What is conduction
While the movement of tectonic plates is usually slow—typically just a few centimeters per year—plate tectonics are linked to several kinds of natural disasters such as
What is tsunamis
Plate boundary zones occur where the effects of the interactions are unclear, and the boundaries, usually occurring along this
What is broad belt
This is thought to be the strongest force driving plate motions
What is subduction
Asthenosphere is described as
What is hotter and flows easily
This may be part of the lithosphere or the asthenosphere at different times depending on its temperature and pressure
What is the mantle
An earthquake can cause this
What is a tsunami
Active zones of mid-ocean ridges, and continent-to-continent rifting are examples of these
What is divergent boundaries
Driving forces advocated at the moment can be divided into three categories based on the relationship to the movement
What is mantle dynamics, gravity, and earth rotation
Plate tectonics came to be generally accepted by geoscientists after this was validated in the mid to late 1960s.
What is seafloor spreading
Lithospheric mantle is overlayed by one or two types of crustal material called
What is oceanic crust and continental crust
Researchers have placed these in the ocean to detect tsunami waves traveling toward land.
What is buoys
When crust divides, what is able to make its way to the surface? What does it create?
What is magma and new crust?
This is mostly driven by the weight of cold, dense plates sinking into the mantle at trenches
What is plate motion
