In writing On the Origin of Species, Darwin synthesized ideas from other publications, as well as observations he made while voy
aging on the H.M.S. Beagle and afterward at home. The publications referenced in the first half of the time line all had a strong influence on Darwin. Which publication provided Darwin the insight that changes to the Earth can happen gradually over millions of years? Principles of Geology Philosophie zoologique Systema Naturae Essay on the Principles of Population
J. Henslow gifted Darwin the first volume of Principles of Geology, written by Charles Lyell. The book explains about the old age of the earth. Accordingly, the slow rate of several geological processes suggests that the earth is very old.
Darwin read the book as the ship was crossing the Atlantic and learned about geological processes occurring over the millions of years. For example, he learned that the earth's surface was not formed by some catastrophic event.
In his book, Lyell explained the slow and gradual geological processes like erosion gave rise to the vast landscapes present on the earth's surface.
Darwin compared the time taken by geological processes to form the earth's surface and reasoned if these millions of years were enough to support the evolution of species.
The phases of the Moon depend on its position in relation to the Sun and Earth. As the Moon makes its way around the Earth, we see the bright parts of the Moon's surface at different angles.
Mars and Moon are the locations from which meteorites would come.
Option (c);
<u>EXPLANATION: </u>
The meteorites found on Earth look like martian crystal rocks.
These might be first ejected into space during a collision of an asteroidal object with Moon or Mars and then it got into the Earth orbit because of the force produced during the collision.
There are around seventy meteorites recognised to have come from the planet Mars till up to the present date.
There are three types of meteorites such as Martian meteorites and a sample of two lunar meteorites.
To identify the origin of the meteorite, the scientist tries to identify the type of rockfollowed by analysing the chemical composition and then try toidentify its age.
