Consider the following statements:
1. Sea floor spreading was proved by palaeomagnetism.
2. Andes Mountains are the result of the convergence of oceanic plate with continental plate.
3. According to Wegener, Peninsular India was part of Gondwana land.
4. How many of the statements given above are correct?

Correct option is C

The Correct answer is(c) All three
Explanation:
. Statement 1 is  correct. Palaeomagnetism, specifically the symmetrical magnetic stripes found on either side of mid-ocean ridges, provides strong and primary evidence for the seafloor spreading theory, confirming the continuous creation and outward movement of oceanic crust.
. Statement 2 is  correct. The Andes Mountains were formed at a convergent plate boundary where the denser oceanic Nazca Plate subducted beneath the less dense continental South American Plate.
. Statement 3 is  correct. According to Alfred Wegener's theory of continental drift, Peninsular India was part of the ancient southern supercontinent called Gondwanaland, which also included South America, Africa, Australia, and Antarctica. 
Information Booster:
. The theory of seafloor spreading, proposed by Harry Hess, provided the missing mechanism for Wegener's continental drift theory.
. The subduction process that formed the Andes created the Peru-Chile Trench along the coast and a volcanic arc mountain range with significant seismic activity.
. Gondwanaland was the southern part of the supercontinent Pangaea, which later broke apart into present-day continents. 
Additional Knowledge:
Statement 1: Sea floor spreading was proved by palaeomagnetism. (Option a, b, d depending on combination)
. Rocks closer to the mid-oceanic ridges have normal polarity and are the youngest, while the age of the rocks increases as one moves away from the crest, which is a key piece of evidence from palaeomagnetism.
. This magnetic striping pattern confirmed the continuous process of new crust formation and lateral movement, effectively proving seafloor spreading. 
Statement 2: Andes Mountains are the result of the convergence of oceanic plate with continental plate. (Option a, c, d depending on combination)
. This type of convergence (oceanic-continental) creates extensive mountain systems and a trench along the boundary.
. The collision of the Indian Plate with the Eurasian Plate, in contrast, is an example of continent-continent convergence, which formed the Himalayas. 
Statement 3: According to Wegener, Peninsular India was part of Gondwana land. (Option a, b, d depending on combination)
. The Peninsular Plateau is considered the oldest and most stable landmass of the Indian subcontinent because it was part of this ancient, stable craton.
. The Himalayas, in contrast, are geologically young fold mountains formed much later due to the collision after the breakup of Gondwana.
