Answer:

Structural Trap , Stratigraphy trap , combination Trap .

Explanation:

Structural Trap -

It is a type of geological trap that is formed due to the tectonic , gravitational , changes in the structure of the subsurface and the compactional processes .

These changes leads to the formation of the petroleum reservoir by blocking the upward migration of the hydrocarbons.

They are one of the important traps since , it represents majority of the world's discovered petroleum resources .

The examples of the structural trap are -

the fault trap , anticline trap , and the salt dome trap .

Stratigraphy Trap -

The formation of Stratigraphic traps are due to the vertical and lateral variations in the texture , porosity , thickness and the lithology of the reservoir rock .

The examples of the Stratigraphy trap are -

An unconformity trap , a reef trap and a lens trap .

Combination Trap -

The trap having two or more trapping elements are called Combination traps. This type of trap is due to changes in lithology and tectonic process.

The examples of the Combination trap is -

salt dome.

Why is the earth's lithosphere considered a giant jigsaw puzzle?

Pavlova-9 [17]

The lithosphere, which is the rigid outermost shell of a planet (the crust and upper mantle), is broken up into tectonic plates. The Earth's lithosphere is composed of seven or eight major plates (depending on how they are defined) and many minor plates. Where the plates meet, their relative motion determines the type of boundary: convergent, divergent, or transform. Earthquakes, volcanic activity, mountain-building, and oceanic trench formation occur along these plate boundaries. The relative movement of the plates typically ranges from zero to 100 mm annually.[2]

Tectonic plates are composed of oceanic lithosphere and thicker continental lithosphere, each topped by its own kind of crust. Along convergent boundaries, subduction carries plates into the mantle; the material lost is roughly balanced by the formation of new (oceanic) crust along divergent margins by seafloor spreading. In this way, the total surface of the lithosphere remains the same. This prediction of plate tectonics is also referred to as the conveyor belt principle. Earlier theories, since disproven, proposed gradual shrinking (contraction) or gradual expansion of the globe.[3]

Tectonic plates are able to move because the Earth's lithosphere has greater strength than the underlying asthenosphere. Lateral density variations in the mantle result in convection. Plate movement is thought to be driven by a combination of the motion of the seafloor away from the spreading ridge (due to variations in topography and density of the crust, which result in differences in gravitational forces) and drag, with downward suction, at the subduction zones. Another explanation lies in the different forces generated by tidal forces of the Sun and Moon. The relative importance of each of these factors and their relationship to each other is unclear, and still the subject of much debate.
