What can a siesmic wave do if it can travel through liquids gases and solids in the continental and or oceanic crust?

First we must define seismic waves, it consists in two forms, P-waves (longitudinal/compressional waves) and S-waves (traverse or shear waves), P-waves travel faster than S-waves and can pass through solids and liquids of the Earth's inner parts, however, they do least damage due to the way they move (up/down). S-waves, however, do the most damage, they move sideways and has a large amplitude and thus does the main damages earthquakes; nevertheless they do not travel through liquids. Therefore, seismic waves that travel through the Earth's crust does no damage as even close to the surface, the P-waves are virtually safe, travelling a long way, it runs out of energy.

Is it better to drill through Oceanic Or Continental Crust?
the oceanic crust because it is much denser so there is less chance of the hole collapsing
If a plate of ocean crust plunged underneath a continental platewhat landforms do you expect to develop?
When the oceanic plate is subducted underneath the continental plate, the oceanic plate begins to melt. The molten material rises through the continental crust and a volcano forms.
What is the difference between the continental crust and the oceanic?
Continental crust is much older, granitic in nature, and less dense than oceanic crust which is composed of basaltic rock. Oceanic crust is in a constant state of creation and destruction through the processes of plate tectonics. Oceanic crust is also considerably less thick than continental crust.
What happens when oceanic crust and continental crust collide?
Subduction occurs on continental boundaries because oceanic sub floor is denser and heavier than the lighter more buoyant crust. The oceanic crust slides under the continental crust areas usually on a plate boundary. This is in a recycle style mode that constantly is remaking the ocean floor. The oldest rocks on the ocean bottom are a drop in the geologic time bucket, compared to the rock ages on land.
What is crustal shortening?
Crustal shortening is the reduction of the size of the Earth's crust through tectonic activities such as those found at a convergent plate boundary. When an oceanic crust collides with a continental crust, the denser oceanic crust subducts beneath the continental crust. This causes the oceanic crust to be subducted back into the mantle and melt, reducing the size of the crust. When two continental crusts collide and neither subducts, the material is being pushed up towards Earth's surface, resulting in mountains like Mount Everest. This causes the crusts to reduce in size.
Would it be easier to drill through the oceanic crust or the continental crust?
Continental crust is easier. Continental crust is less dense than oceanic crust, which is made of basalt. (Basalt is very dense.)

What are siesmic waves used for?
Siesmic waves are the propogation through the ground of any energy, such as sound waves or impact forces.
How does a trench forms?
They form when the oceanic crust goes under the Continental crust. The oceanic crust then forms the trenches through a process called subduction.

How was plate tectonics proven through continental drift?
The creation of crust at the mid-oceanic ridges.

How does a deep-ocean trench form?
They form when the oceanic crust goes under the Continental crust. The oceanic crust then forms the trenches through a process called subduction.
What happens when continental collides with continental crust?
The oceanic crust is force down into the mantle in a process called subduction. The subducting oceanic plate will introduce water into the hot mantle, causing some of the rock to melt. The molten rock will rise through the overriding continental crust to form volcanoes.
Why does one continental plate slide under the other?
Because magma rises through hot spots( holes in the ground on the ocean floor) and cools forming new crust which repeats over hundreds of years making the oceanic crust more dense than continental crust. Since the oceanic crust is more dense, it sinks faster causing it to slide under the continental crust
How do volcanos form at a plate boundary?
When tectonic plates converge together at the bottom of the ocean the oceanic plate goes under the continental plate because the oceanic plate weighs more and then the oceanic plate pushes up the continental plate which forms mountains and sometimes the tectonic plates let magma through which goes up through the continental plate and then opens a hole at the top of the mountains called a vent which is where the steam, volcanic ash, debris and lava come out of.
