Describe in basic terms how elements were/are formed during the big bang (including the reasons why only H/He formed abundantly)‚ during normal stellar operation (including why some elements such as Si and Fe were formed more abundantly)‚ and during supernova processes/explosion Big bang only thing that forms out of the big bang is the nuetrons. Protons plus electrons = hydrogen. Hydrogen fuses the helium. There are no stable atoms with 5 or 8 nucleons (hydrogen would have 5‚ helium would have

ASEPTIC TECHNIQUES AND SOURCES OF MICROBIAL CONTAMINATION. Introduction The spread of infections has come to a point where it has become catastrophic. Aseptic technique is the method used to prevent contamination of infections. It is widely used in hospitals‚ pharmacy‚ and pharmaceutical industries and in laboratories. Different establishments have come up with more ways to improve infection control. In hospitals health care acquired infections are costing the NHS £1 Billion a year and

when volcanic islands collided in the south west of America‚ where the North American plate is now. Mountain building occurred about 75 million years ago when the uplift of almost 2 miles in the region‚ (called a Laramide orogeny event) started and created the Colorado Plateau. The rocks in the Grand Canyon were igneous or sedimentary rocks before the collision of tectonic plates. The collision pushed the plates under the earths crusts. The rocks recrystallized under high temperature and pressure

EARTHQUAKES 8 MEASURES TAKEN TO MINIMIZE EARTHQUAKES 9 BIBLIOGRAPHY 11 INTRODUCTION Earthquakes are caused by the movement of the earth’s tectonic plates. Earthquakes occur where the earth’s plates meet along plate boundaries.For example as two plates move towards each other‚ one can be pushed down under the other one into the mantle. If this plate gets stuck it causes a lot of pressure on surrounding rocks. When this pressure is released it produces shock waves. These are called seismic waves.

During this event‚ Franklinian basin probably transformed into a foreland basin as a result of the subduction of Iapetus Oceanic plate which preceded the formation of supercontinent Pannotia.

Austronesian Migration Theory propounds on the expansion of a group of people called the Austronesians from Asia into the Pacific by means of Taiwan 6‚000 years ago. It was a theory proposed by Peter Bellwood a professor of Archeology. The theory largely explains the similarities in culture‚ language and physical attributes in different countries in the most Asian countries. The Austronesian migrations began from the Chinese mainland‚ reaching Taiwan first in 3500 BC then the Philippines by 3000

How Old is the Earth? James C. Wood‚ Sr. Liberty University PHSC-210 – Elements of Earth Science Instructor Mark Ivins March 2‚ 2015 Introduction The scientific community has been split on many things and the age of the earth is one of the subjects in which it is split. There are some who believe that the earth is billions of years old based on scientific measurements and there are others who believe that the earth is only thousands of years old based off of what the Bible teaches.
