Holmes’s career as a geologist started soon after his graduation from Imperial College of Science in London in 1910. To help pay his college expenses, he went to work as a prospecting geologist in the country of Mozambique. Unfortunately, he also wound up catching malaria. He returned to England in 1913 just when World War I was starting. As luck would have it, he was too sick to go into the army and fight. D. As a graduate student, Holmes read about the work in radioactivity done by Rutherford and Boltwood.

In addition to the mid-ocean ridge, Heezen and Tharp’s maps also showed deep valleys, many of which run along the edge of the continents. These valleys are known as submarine trenches. In many cases, these trenches, which make an almost complete ring around the Pacific Ocean, contain enormous piles of sediment. One other unusual feature on the maps is a series of fractures, or faults, that cut across both the ridge and the trenches. Many of these fracture zones would cause the ridge to be offset and split by several hundred kilometers.

Atoms have two main parts. First, in the center of the atom, is the nucleus. This is where most of the mass of an atom is located. The nucleus is made up of two different particles: protons, which have a positive charge, and neutrons, which have no charge. The second main part contains even smaller particles that move around the outside of the nucleus: These particles are called electrons. Electrons have a negative charge, and they produce electricity. Each type of element has its own special atom with a different number of protons in the nucleus.
