Information gathered from observing a plant that grows 3 cm - Brainly Black, in turn, presented them to the Royal Society of Edinburgh, to be used to illustrate 'Hutton's Theory of the Earth'. Then, as this ocean receded, all of the rocks observable at Earths surface were precipitated out of the ocean in a definite order to form the current landscape. The theory took its name from Neptune, the ancient Roman god of the sea. origin of basalt disproved the Neptunist theory that all rocks were formed by sedimentation from primeval oceans. Within a year he published the first modern textbook on descriptive mineralogy, Von den usserlichen Kennzeichen der Fossilien (On the External Characters of Fossils, or of Minerals; 1774).

In the early 19th century the origin of igneous rocks was hotly debated between the "Plutonists," who believed in an igneous origin, and the "Neptunists," who believed that the crystalline nature originated as a submarine precipitate. These rocks vary in size and colour. See also extrusive rock. Igneous rocks are formed from the solidification of molten rock material. Language links are at the top of the page across from the title. Werners theory of neptunism is a perfect example that assumptions in science are toxic to a well-developed understanding of the world. Rocks were divided into two groups: the primitive rocks, that is . The correct answer is: Before life, the earth was entirely covered by water.
