Subduction occurs where the oceanic crust bends down toward the mantle at a(n)?
Seafloor spreading occurs along mid-ocean ridges. Mid-ocean ridges are large mountain ranges on the ocean floor. The shifting in the rock causes the seafloor to spread and allows magma to bubble and form more mountains on the ocean floor.
How does a volcano erupt and what causes it to erupt?
When a destructive boundary of two tectonic plates occurs the oceanic crust sinks underneath the continental crust as it is more dense, the oceanic crust then melts in the subduction zone and becomes magma in the mantle, this increases the pressure in the mantle and causes the magma to shoot up the volcano shaft and burst out of the top, this is an eruption
What process occurs in the hot pliable mantle rock beneath the earths plates?
Convection. The same as the shimmering above a hot road in summer, heated material is less dense and rises over cooler material.convection currents
What is the earths greatest density and this occurs in?
The Earth's core.
Does earths weather occur in the thermosphere?
No, it occurs in the Troposphere.
The slow circulation of the plastic mantle in the earths asthenosphere occurs by what processes?
convection
Which layer of the earth is the place where convection occurs?
Convection currents rese and sink through the mantle and the liquid outer core. In Earth's mantle, large amounts of heat are transferred by convection currents. Heat from the core and the mantle itself causes convection currents in the mantle.
Earths lithosphere is broken into huge moving slabs of rock driven by motions in the mantle?
The motion in the mantle is known as convection currents which helps move earth's slabs, known as plates. Convection occurs in the upper mantle known as the asthenosphere.
Why does convection occurs in the athenosphere?
heat from the outer core and the mantle when it drifts up to the asthenosphere it causes convection.
What name is given to the area where volcanoes often occurs because convection in the earths mantle produces a column of magma that rises into the crust?
hotspots
Where was the continental drift?
Continental drift occurs under the earths crust by convection currents in the mantle which drives the plates. It has been happening since the development of the earths core and is happening now and until the end of the earth.
What is a destructive force caused by convection currents in the earths mantle?
Convection currents in the Earth's mantle are thought to be responsible for plate motions and therefore can ultimately be considered the cause of earthquakes. Mantle upwelling or mantle plumes are also thought to be the cause of hotpots which cause intra-plate volcanic activity such as that which occurs in Hawaii.
How much force does a earthquake?
all is that i know is that it starts with a p

When the shift occurs in the earths crust the energy radiates as what?
what does the energy come out as when a shift occurs in the earths crust called
Earths weather occurs in the thermosphere?
False, it occurs in the troposphere.
Why mantle convection occurs?
