In 1915, Alfred Wegener proposed the theory of continental drift to explain the past and present location of the continents; however, his ideas were met with resistance because he could not provide evidence that would support his hypothesis. Later oceanographers, geologists, and scientists collected more information to verify and explain the theory. In the 1960s, the mechanism and processes were explained by plate tectonic theory. With advancements in science and technology, scientists are still collecting more information. Answer each of the following questions in your own words and in 3–5 sentences: 1.
The Rocket testing started in Berlin in 1930 that would change the face of warfare forever. The very first rocket that the VFR tested was launched in August 1930 named Mirack-1 (Minimum Rocket-1). The next year in April 1931 a scientist named Atosnabruick Reinhold Tiling launched four solid-fueled rockets, but he did not work for the VFR. One of the four Rockets that he launched had reached a height of 6,600 feet in the air at 700 mph, which was very amazing for back in those times. He then made and launched two more rockets that were even more advanced than his first four.

The new theory is called plate tectonics. Soon after the Atlantic Ocean had been mapped, about three hundred years ago, it was noticed that the opposite coasts had similar shapes, but it was not until the middle of the 19th century that accurate maps were published demonstrating that the two coasts could be fitted together quite closely. Some geologists then suggested that the fit of the coasts was not an accident--that the continents were once joined and had subsequently drifted apart. None of the suggestions were taken seriously. In 1912, however, the German meteorologist Alfred Wegener investigated the fit of the Atlantic coasts more carefully than had his predecessors and grouped all the continents together into one great land mass, which he called Pangaea.
19th Century The development of aviation took various paths during the 19th century. The father of aviation, Sir George Cayley was a British aeronautical engineer and inventor. He proved his ideas of flight with experiments involving kites and controlled human-carrying gliders. Charles Augustus Lindbergh was the first person to make a nonstop solo flight across the Atlantic. He made the flight to win the prize of $25,000 offered by Raymond B. Orteig of New York City for the first nonstop transatlantic solo flight between New York City and Paris.
In 1905 Alfred went to work with his older brother at the Aeronautischen Observatorium Lindenberg in Beeskow. The two brothers would be the first ones to pioneer the use of weather balloons to investigate air masses. Alfred Wegener was a meteorologist and explorer who was a pioneer in the studies of not only meteorology, astronomy, and polar exploration, but he also came up with the concept of the Continental Drift Theory. During his lifetime, Alfred was probably known best for his studies in meteorology and his explorations in Greenland. He participated in four separate Greenland expeditions where he and the team that he was with were charged with the duty of studying the last unknown portion of the Greenland coastal area.
Could you imagine being the reason why space travel is as magnificent as it is today? Robert Goddard is the wonderful man behind all of this. Many people were so surprised when he announced that the first rocket fueled with liquid oxygen and gasoline was built and ready to launch! On March 16, 1926 in Auburn, Massachusetts on Goddard’s aunts’ farm, many witnessed the first ever working rocket to launch into space. The rocket traveled for two point five seconds going about sixty miles per hour and soaring forty-one feet in the air then landed one hundred eighty-four feet away.
Alfred Wegener even came up with the Continental Drift theory. Alfred Wegener’s interest in kites and balloons began at the Royal Prussian Aeronautical Observatory near Berlin, Germany. In addition, Alfred and Kurt Wegener used kites and tied balloons to study the higher atmosphere. Without a doubt, Alfred and Kurt Wegener broke the world record for the longest time spent aloft in a hot air balloon with a total of fifty two hours. According to Dr. Johannes Georgi, a meteorologist and Greenland explorer, Alfred Wegener became the first person to trace storm tracks over the large covering of ice in the polar region.
There was a debate on what a planet should be. The debate shows how classification itself is a complex process that takes many years to be precise. In the 1930’s Pluto seemed to meet the criteria needed to be considered a planet, but as time passed scientist began to notice its differences from the rest of the planets. Many scientist seemed optimistic about the demotion of Pluto to a dwarf planet. For many years, scientist had not come to a conclusion on what the definition of a planet was until 2006 after a meeting of the International Astronomical Union.
Alfred Wegener's Biography Alfred Lothar Wegener was born on November 1, 1880. He was interested in geophysics, and also became fascinated with the fields of meteorology and climatology. During his life, Wegener made several key contributions to meteorology; he pioneered the use of balloons to track air circulation, and wrote a textbook that became standard throughout Germany. In 1906 he joined an expedition to Greenland to study polar air circulation. Returning, he accepted a post as tutor at a German university.
