What do you think may happen to the leading edge of oceanic plate as if continues to move downward?
As the leading edge of an oceanic plate continues to move downward into the mantle at a subduction zone, it will experience increased pressure and temperature. This can lead to the release of water and other volatiles, causing melting in the overlying mantle and potentially generating magma. Over time, this process can contribute to volcanic activity and the formation of volcanic arcs. Additionally, the descending plate may also undergo metamorphism and contribute to complex geological formations.

What might happen if damage to the ozone layer continues?
If the ozone layer continues to deplete, there would be UV rays entering the surface of earth. These UV radiations cause various fatal problems to life on earth.
What will happen to the earth if continental drift happens again?
Continental drift never stopped and continues today. It just happens so slowly, we don't notice it. An example of one thing that will happen is because the pacific plate is rotating CCW, in one million years, Los Angeles will be out in the pacific ocean west of San Francisco.
How did the Chile earthquake happen?
Chile is on the western coast of the continent of South America, this is the boundary between two tectonic plates, the Nazca plate (which is an oceanic plate) and the South American plate (a continental crustal plate). In this region the Nazca plate is moving eastwards towards the South American plate. The dense oceanic crust of the Nazca plate is being forced under or subducted beneath the less dense continental crust of the South American Plate. The Nazca and South American plates are converging at a rate of approximately 80mm / year. This causes stress to accumulate resulting in elastic strain which stores elastic potential energy. Once the stress exceeds the strength of the rocks in the crust a brittle failure occurs, causing in this case thrust faulting to occur. The stored elastic strain energy is released in the form of seismic waves. This form of thrust faulting usually results in the most powerful earthquakes and in the past Chile has experienced a magnitude 9.5 earthquake caused by the same tectonic plate motions - the most powerful ever recorded. Please see the related question for further information.
How many earthquakes occur around the 'ring of fire'?
The "ring of fire" comprises the seaboard costs of the countries surrounding the Pacific Ocean. The zone is where oceanic crust is being subducted under continental crust and the location of many volcanoes and continual earthquake activity. It is impossible to give you a count of the number of earthquakes that happen in the zone, earthquake activity is continuous.
Does most earthquakes happen near near active margins?
It depends on the meaning of "tend to." They tend to not be as common, but yes they do occur for a variety of reasons, including glacial rebound ... the great ice sheets that covered continents, such as North America, were so massive that they actually pressed the North American continent down, like loading a massive block of ice onto a relatively small ship, it caused the ship -- North America -- to sink down into the mantle a bit. When the great ice sheets that caused the continent to be pressed downward melted and the water from it drained away, the continental interior was no longer in equilibrium -- in the previous hypothetical analogy, after the massive block of ice melts off the ship, its mass no longer presses the ship downward and the ship bobs upward. The continent rebounds upward from its massive ice-depressed lower level, but the upward motion is not smooth and causes strain within the continental bedrock, leading to earthquakes deep within the continent instead of the more common earthquakes occurring at the continent's edges.
What do you think may happen to leading edge of plate a as it continues to downward?
As the leading edge in forced down it is heated up and becomes part of the molten magma below.
What may happen to the leading edge of plate as it continues to move downward?
The edge of the plate will heat up and become part of the molten mantle.
May happen to the leading edge of plate as it continues to move donwnard?
The leading edge of a plate can subduct beneath another plate or slide past it along a transform boundary as it continues to move downward. This process can generate earthquakes, volcanic activity, and the formation of mountain ranges at convergent boundaries, while at transform boundaries, it can create fault lines and seismic activity.
When a pearl is dropped into a dense liquid it quickly acquires a uniform non accelerated motion downward why does this happen?
It accelerates quickly up to a low terminal velocity, then continues at constant velocity. At terminal speed, the downward force of gravity and the upward force of liquid resistance are in balance.
What will happen if war continues?
if the world continues everyone would die
Do earthquakes happen when a continental or oceanic plate moves over a hot spot?
Earthquakes happen because of continental plate shifts. Oceanic plate shifts cause title waves.
What explains the observation that when a continental and oceanic plate collide the oceanic plate dives down under the continental plate?
This phenomenon, known as subduction, occurs because oceanic plates are denser and thinner than continental plates. When the two plates collide, the denser oceanic plate is forced beneath the less dense continental plate due to gravitational pull. This process results in the oceanic plate descending into the mantle, leading to the formation of deep ocean trenches and volcanic arcs.
How did the Chilean earthquake happen?
the oceanic plate crased into the continental plate.
Do hurricanes happen in the ocean?
Yes, hurricanes are a tropical oceanic phenomenon.
What happen when cold and warm oceanic water meet?
hurricane or tornaro
What would happen if the thinning of ozone continues?
If the thinning continues, UV will enter the earth. There will be no life left.
What would happen if the continental crust and the oceanic crust went into each other?
In a convergent plate collision between continental and oceanic plates, the more dense oceanic plate would subduct, or move underneath, the less dense continental plate, eventually melting into the mantle at the leading edge.
