Ozone Layer In the Stratosphere (between 10 and 50 kilometers high) is the layer containing most of the atmospheric ozone and this is mainly concentrated at about 25 kilometers up. Ozone is produced in the ozone layer mainly through ultraviolet light from solar radiation (hn) colliding with diatomic oxygen (oxygen made of two atoms). Diatomic oxygen in the stratosphere absorbs the majority of the harmful ultraviolet radiation (anything with a wavelength smaller than 240 nm) and in doing this the absorbed energy splits the molecule leaving two individual oxygen atoms.

Jupiter’s Moons On the 7th of January 1610 an Italian astronomer and physicist by the name of Galileo Galilei used a new instrument (originally a child’s toy) called a telescope to observe Jupiter. On this day he discovered small bodies around Jupiter which he initially believed to be stars. It wasn’t until later after observing them orbiting the planet that he determined they were some of its moons. By the 11th of January Galileo had discovered four large moons in total which are today known as the Galilean moons. n as the Galilean moons. When Galileo’s discovery was made public in a book called ‘Sidereus Nunciut’ it made Galileo famous as well as changing the view of the cosmos dramatically. Classical astronomy suggested that Earth was the centre of the universe and everything revolved around us. This idea was also endorsed by the church as this helped imply the divinity of Earth and god’s creation the life upon it (mainly humans). Copernicus had previously suggested that Earth actually evolved around the sun and the moon around Earth but many people did not except this ‘Theory’. Now Galileo too provided evidence to contradict the classical and religious idea of our importance in the universe. For this heresy Galileo was locked up for many and ordered to renounce what he had published in his book. Although Galileo had refused at first, the threat of being put to death by the church made him concede to their demands. But the truth cannot be silenced forever. Initially the Galileon moons were known collectively as ‘Medicean Stars” a name given to them by Galileo...

  Your Atoms Test may take a few moments to load.     If you have to navigate away from this page for any reason, don’t worry, you will have the option to resume your test from the point you left upon your return. The test may have multiple choice, multiple answer or true/false questions and is timed but has no time limit. It should be considered an aid to study for exams or merely a test of your knowledge base giving you indication of areas you may need further study in.   Once you have completed your test you will be able to review your results. This will give you some indication of the area you need further study or which areas you are proficient. We recommend you take the Atoms Test before reading the subject matter. If you score 80% or more than you have the option of skipping the section but if you score less than 80% we recommend you read the material associated. Then try the test again until you are able to gain a passing result of 80% correct.       Error: Embedded data could not be displayed.     Why Use the Atoms Test?   As previously stated tests give the user indication of their strengths and weaknesses.
