环境地质学概念及学习意义 Concept of Environmental geology 1、环境地质学概念( Concept) 是认识“系统环境”的一门综合性学科, 是研究环境科学、地质科学,系统了解地球本身的一门基础科学。 人类只有一个地球,共同的家园。 2、环境地质学学习意义( why study it) 不了解地球的学者不算一个完美的学者,环境地学知识能使其它 学科,在设计施工、决策上站在“地球环境”的高度上考虑问题。 3、授课对象( who study it) 主要针对非地学类专业(文科、非地学的理科、如农业、电子、医 也可针对地学类学生 环质 Environmental Geology

星际邳境 The Planetary environment 1)囵的形成 Our Universe 大爆炸理论:“ Big bang”-发生在150亿年前 In recent decades scientists have been able to construct an ever clearer picture of the origins of the solar system and before that of the universe itself. Most astronomers now accept some sort of Big Bang as origin of today' s universe. at that time enormous quantities of matter were created and flung x ja violently apart across an ever- larger volume of space. The time of Big Bang can be estimated in several ways perhaps the most direct is the back-calculation of the universe's expansion to its apparent beginning. Other methods depend on astrophysical天体物理 models of creation of the elements or the rate of evolution of different types of stars. Most age estimates overlap in the range of 15 to 20 billion years, although a few researchers suggest an age closer to 10 billion years 环质 Environmental Geology

T星欧邳境 The Planetary environment 2)彩的形成 Our Universe 大爆炸理论:在重力作用下、碎片聚集、能量释放 From the debris of the Big bang formed the stars, as locally high concentrations of mass were collected together by gravity, and some became large and dense enough that energy-releasing atomic reactions were set off deep within them. Stars are not permanent objects. They are constantly losing energy and mass as they burn their nuclear fuel. The mass of material that initially formed the star determines how rapidly the star burn; some stars burned out billions of years ago, while others are probably forming now from the original matter of the universe mixed with the debris of older stars 环质 Environmental Geology
