In an oil trap, liquid petroleum is typically found in the reservoir layer, which is often sand or porous rock that can store hydrocarbons. This layer is usually situated above an impermeable cap rock that prevents the petroleum from migrating further upward. The specific placement can vary depending on the geological formations present in the area depicted in figure 4-1.
Liquid petroleum is typically found in the reservoir rock layer of an oil trap. This layer is usually porous and permeable, allowing the oil to accumulate in significant quantities. Above the reservoir rock, an impermeable cap rock layer traps the oil, preventing it from migrating to the surface. This geological structure creates the conditions necessary for the accumulation of hydrocarbons.
Straight talk from the Oklahoma Oil Fields!Subsurface reservoir of shell oil and fuel (Petroleum trap) :Mixture of Water, Shell Oil or Crude and Natural Gas confined in porous rock like sandstone (Clastic). Natural Gas being the lightest occupies the top of the trap a layer of rock which prevents the upward escape of petroleum. Since Gas is lighter it moves upwards in the trap leaving a layer of oil and then water. Water has a greater density than oil leaving the oil layer to move up and water to move downwards in the trap.
Please refer the below link http://en.wikipedia.org/wiki/Chordiant Chordiant Framework is same as MVC2 architecture, but instead of ORM and service layers there will be separate layer like Chordiant service layer and Chordiant JXP layer (this is same as hibernate or ibatics). UI Service layer ORM layer JSF Chordiant Service layer Chordiant JXP layer
The data link layer (2nd layer), the network layer (3rd layer) and the transport layer (4th layer) each handle their own specific errors, which should prevent errors in both directions. Any untrapped errors will result in a corrupt transmission which may or may not be handled by the appropriate endpoint, dependant upon the protocol.
with single programming language we cannot do anything on the internet. Actually every application in java is divided into three layers. Presentation layer, Application layer, Data layer. Every layer has its own specification. Presentation layer role is to interact with client means presentation layer takes input from the user and send it to Application layer. Application layer is a business logic layer. All the logic is done in this layer. Data layer contains the data. for example:- suppose user enters student no. and student name in presentation layer, from here the data is send to application layer. In application layer we can write the logic for inserting, deleting, retriving and modifying the user data in database. From here the controller goes to datalayer to fetch data from database and sends the data back to user then the user see the corresponding data in the presentation layer. For presentation layer: html, jsp, velocity etc are used. For application layer: ejb, hibernate....... for data layer: oracle.......

The core is the chemical layer of the Earth with a liquid layer (the outer core), and a solid layer (the inner core).
The molten layer refers to the outermost liquid layer found in the Earth's core. It is composed of molten iron and nickel, and it is responsible for generating the Earth's magnetic field through the movement of this liquid metal.
Petroleum has a lower density than water, allowing it to float on top of water. Additionally, petroleum is immiscible with water due to differences in polarity, preventing them from mixing and resulting in the formation of distinct layers.
The least dense liquid is typically found at the top layer when multiple liquids are combined, such as in a mixture of oil and water. Since oil is less dense than water, it will float on top, forming a distinct layer. This phenomenon can also be observed with other liquids of varying densities, where the least dense liquid will always rise to the surface.
The layer that contains liquid rock is the mantle, which is located beneath the Earth's crust. Magma, which is molten rock, can be found in the mantle and can sometimes rise to the surface through volcanic activity.
The crust. There are no fossils in the core as the outer core is liquid and no organisms have lived on the inner core.
The liquid layer of the Earth's core is called the outer core.
