Answer 1

• The neptunists and plutonists differed in that the neptunists believed that **all crustal rock recipitaed from an ocean** and the plutonists, who were proven right, believed that **igneous rock came from molten lava**.

Explanation :

• The Neptunist theory was prevalent in the 18th century and believed that all rocks, including igneous rocks, were precipitated from a universal ocean. The Plutonists, on the other hand, believed that igneous rocks were formed by the solidification of magma or lava, and that they could intrude into and alter existing rocks. Plutonism eventually became widely accepted due to the work of geologists such as James Hutton and Charles Lyell.
