In Chile, where Darwin saw earthquakes and volcanoes, he began to see what must have happened. The centre of the earth, he decided, was very hot. The surface of the earth was thinner in some places. It was in these places that earthquakes and volcanoes developed.
As the Beagle sailed around the world, Darwin began to wonder how life had developed on earth. He saw volcanic islands in the sea, and wondered how living things had got there.
But people who believed every word of the Bible thought that God had made all creatures and Man. But, if that was true, why did some of the fossils look like" mistakes" which had failed to change and, for that reason ,died out
On went Beagle, to Tahiti, New Zealand and Australia. There, Darwin saw coral and coral islands for the first time. How had these islands come about Soon, he had the answer. Coral was made up of the bodies of millions of tiny creatures, piled up over millions of years— a million years
A. He fell in love with one of his cousins.
B. He kept a journal while on sea and noted down his observations.
C. He still believed every word in the Bible.

Earthquakes are the most lethal of all natural disasters. What causes them Geologists explain them in terms of a theory known as plate tectonics. Continents are floating apart from each other, this is referred to as the continental drift. About sixty miles below the surface of the sea, there is a semimolten bed of rock over which plates, or slabs, carry continents and sea floors at a rate of several inches a year. As the plates separate from each other, a new sea floor is formed by the molten matter that was formerly beneath. Volcanic islands and large mountain ranges are created by this type of movement. The collision of plates causes geological instability such as that in California called the San Andreas Fault, located between the Pacific and North American plates. The plates there are constantly pushing and pulling adjacent plates, thereby creating constant tremors and a potential for earthquakes in the area.
