the Earth ’s continents relative to each other. The hypothesis that continents ’drift ’ was first put forward by Abraham Ortelius in 1596 and was fully developed by Alfred Wegener in 1912. However‚ it was not until the development of the theory of plate tectonics in the 1960s‚ that a sufficientgeological explanation of that movement was found. |Contents | | [hide] | |1 History

Millions of years ago Pangaea is what was believed to be‚ and now has evidence to support‚ the first continent on earth. It is referred to as the super continent as all existing continents were connected to it. In Greek‚ Pangaea is defined as “all the earth”; the man who came up with theory was Alfred Wegener. Wegener had a PhD in astronomy but always had an interest in geoscience. “Wegener was browsing in the university library when he came across a scientific paper that listed fossils of identical

Prior to use‚ melt and hold at 50c in a water bath 5 tubes of 9.0 ml trypticase soy (TS) broth 1 ml sterile pipettes Pipette aids Methods: 1. We began the experiment by marking the plates and place them in order from 10^5‚ 10^6‚ 10^7‚ then have the blank dilutions ready in order from 10^-4‚ 10^-5

contaminated and just left as agar. Having a sample of agar that wasnt exposed to any bacteria will provide a clear picutre of what grew on the agar upon feeding bacteria to it. 2. Why shoudn’t a student swab his or her mouth or cough onto an agar plate to initiate a culture? Even though most bacteria in the human body is harmless‚ if one was knowingly or unknowingly ill then harmful bacteria could be bread. 3. Why isn’t the upper lid of the Petri dish completely removed during the inoculation

Have you ever wondered what has to happen to make the Earth quake? British engineer John Michell did. He was one of the first fathers of seismology and was also the first to correctly state what the cause of earthquakes was. In 1960‚ Michell noted that “earthquakes and the waves of energy that they make are caused by shifting masses of rock‚ miles below the surface” in a scientific memoir (USGS‚ 32). In order for you to completely understand the process of an earthquake you must first understand
