Question

Which of the following statements were not true according to the "Theory of plate Tectonics”. i) The crust of carth has been formed out of seven major and seven minor plates. 1M ii) The movement of the plates results in folding, faulting and volcanic activity, iii) The plate movements were classified into two types such as convergent & Divergent. iv) The position & size of the continents have changed due to this movements. A) () & (iii) B) (ii) & (iv) C) (iii) & (iv) D) ()&(iv)​

Answer 1

In this thesis, the thermal and mechanical structure of convergent plate margins will be investigated by means of numerical modelling. In addition, we will discuss the implications of modelling results for geological processes such as metamorphism or the break-up of a plate at a convergent plate

Answer 2

Answer:

The plate movements were classified into two types such as convergent & Divergent is not true according to the "Theory of plate Tectonics”.

Explanation:

i) Seven major plates and seven smaller plates have come together to form the earth's crust.

• Seven major plates and another eight or so lesser plates cover the majority of the planet.
• The seven primary plates are the African, Antarctic, Eurasian, North American, South American, India-Australian, and Pacific plates.
• The Arabian, Caribbean, Nazca, and Scotia plates are a few of the less significant plates.

ii) Folding, faulting, and volcanic activity are caused by plate movement.

• Examples of the mechanisms involved in the production of orogenic mountains include faulting and volcanic activity.
• Geologists refer to the process of mountain creation as a process.
• The way a tectonic plate folds depends on the collision with another plate.
• A portion of the earth's surface becomes a mountain as a result of the collision.

iii) Convergent and divergent plate movements were the two categories into which they were divided.

• Some plates move in close proximity to one another, converge, and create boundaries.
• Divergent boundaries are produced when some plates migrate apart.
• They could also occasionally move past one another horizontally and create a transform barrier.

iv) Due to these shifts, the continents' positions and sizes have shifted.

• Convection currents in the molten rock in the Earth's mantle beneath the crust are most likely to blame for the movement of these tectonic plates.
• The immediate consequences of this tectonic shift are earthquakes and volcanic eruptions.
• The movement of entire continents over millions of years is the long-term outcome of plate tectonics.

Final answer:

The statement The plate motions were categorized into two types such as Convergent & Divergent is therefore untrue in accordance with the Theory of Plate Tectonics.
