depending on its age‚ and is broken into plates‚ known as the tectonic plates. Within the lithosphere is the crust as a portion of the upper mantle. The crust is the outer most portion of the earth and takes up less than 1% than the total volume of the earth. It is commonly compared to the skin of an apple‚ whereas the apple represents the earth. The temperature of the crust varies from the air on top‚ to upward of 1600 at the deepest parts. The tectonic plates are part of the crust of the earth‚ moving

GENERAL SCIENCE POINTERS BASIC CONCEPTS AND LAWS Science and Technology Science - is a systematic study that is concerned with facts and principles‚ and methods that could be observed in our natural or physical and social environment. It comes from the Latin word ’scire’ that means ’to know’. - is both a body of knowledge and a process – away of thinking‚ a way of solving problems The Branches of Science THE PHYSICAL SCIENCES • Physics: The study of matter and energy

that is why the earth has the formation that it currently has‚ with seven large continents. With an area of 41‚105‚000 square miles‚ the Atlantic Ocean is currently just a little over half the size of the Pacific Ocean. The plates of the earth have never stopped moving. As the plates continue to shift‚ the Atlantic Ocean continues to grow each year‚ while the Pacific Ocean continually shrinks every year. While the Atlantic Ocean grows approximately one inch every year‚ the Pacific Ocean shrinks approximately

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

INTRODUCTION Microorganisms such as bacteria‚ fungus‚ mold‚ and yeast are present and common in almost every environment on earth. The normally microscopic organisms can easily be seen using differing types of agar‚ which creates an ideal environment for the organisms to form colonies‚ which are groups of hundreds of organisms that can be seen with the naked eye. In order to see individual microorganisms‚ it is necessary to use the magnification of a high-powered microscope. These techniques

The mouth-watering aroma flooded my nose as I entered a room full of patrons and food. I was mesmerized by the atmosphere of the restaurant. The sound of the music mixed with the clashing of utensils and plates‚ and the sizzling sound of food being cooked by professionals was all too familiar. It was here where my family had our very first high class dinner. As my parents were ordering from the menu‚ I was witnessing the chef preparing beef. He first placed the beef on a pan and poured
