Developed the theory of continental drift to explain why the continents look like pieces of puzzles that are no longer together (Pangea)

Recognized the order of rock layers and tried to explain them by formulating rules for a general interpretation of sediments. He succeeded, creating the main principles of modern stratigraphy that we still use today.

His studies of the S Pacific, NW United States, Europe, and elsewhere led to changes in ideas on mountain building, volcanism, and the origin of the continents and oceans.

Discovered, in 1906, that the speed of earthquake waves becomes faster with greater depth of penetration into the Earth

He developed the first geological map of Germany and was the first to determine that granites were formed by igneous processes and that the Alps resulted from an upheaval in the earth's crust.

discovered in the 1890s "that the atmosphere consists of layers. Bort notices that air temperature decreases steadily up to about seven miles, but remains constant at higher altitudes. After more than 200 balloon experiments, he suggests that the atmosphere is divided into two layers called the 'troposphere' and the 'stratosphere.'"

He discovered that hundreds of flat-topped mountains, possibly sunken islands, that snap the Pacific floor. Later, in 1960 he proposed that the movement of continents was a result of sea-floor spreading.

Discovered the irregularity in the moons motion, known as evection and made original observations about the motions of the planets.

He developed a theory relating Earth's motion to long-term climate change and ice ages. He came up with a mathematical theory of climate uses variations in solar radiation based on season and latitude.

Wrote one of the first papers on glacial movements and deposits.

Cosmic Radiation: In 1912, he traveled to 17,500 ft. in a hot air balloon (no oxygen) and observes that radiation increases with altitude. While he further explored, he was convinced that radiation is coming from space.

contributed knowledge about shape and size of earth, and proved that the earth is not the center of the solar system because its the sun

Developed the first scientific model of clouds, discovered what keeps hurricanes whirling forward, and revealed what drives the atmospheric currents in the tropics

Discovered how to calculate the age of rocks in 1907 by "measuring the rate of its radioactive decay." Based on this research, he claimed Earth's age to be 2.2 billion years. (Although today we think this age is twice as old, his estimated age was a huge leap during that time.) "Boltwood's formulas are compatible with several radioactive elements, including carbon-14, which has been used to date historical artifacts."

Discovered evidence, during the years 1830-1833, supporting the idea of uniformitatianism which is the "idea that the Earth was shaped entirely by slow-moving forces acting over a very long period of time." This idea was not well accepted during his time as the idea of catastrophism, "a geologic idea that uses biblical chronology to date the Earth," was more accepted.
