INTRODUCTION Plate tectonics The large scale motions of the earth’s lithosphere are describe by a scientific theory called plate tectonics which explains that Earth’s outer layer is made up of plates‚ which have moved throughout Earth’s history. The theory was developed during first decade of 20th century (by a famous advocate Alfred Wegener) on the older concept of continental drift and was accepted by many geoscientific communities. There are currently seven major and many minor plates are

(Henning 1981). By the Age of Dinosaurs‚ 300 million years ago‚ insects were abundant in number and diversity. Like the dinosaurs‚ some pre-historic forms of insects were enormous: the dragonfly Meganeuropsis had a wing span of 35 inches‚ and the giant Mesozoic relatives of the scorpions‚ the eurypterids‚ measured over 6 feet in length (Borror and others 1992). The origins and evolution of insects and related groups is complex. Insects themselves may have descended from the many-legged animals that

GOTTHARD BASE TUNNEL‚ SWITZERLAND 1. INTRODUCTION Currently under construction to stretch a record length of 57 km‚ the Gotthard Base tunnel located in Switzerland spans the north of Europe‚ spanning through the Swiss Alps to the south of Europe. This railway tunnel has been designed to bypass the inefficient route of windy roads and cutting down travel time. The Gotthard Base tunnel consisting of twin tunnels is connected by cross passages at every 325m. The twin tunnels have been constructed

Chapter One: The Nature of Science As you look around‚ science is everywhere. From the food you eat‚ clothes you wear‚ or the television we watch‚ the success of science is made evident. In 250 B.C.‚ even with less advanced technology‚ the Egyptians successfully measured the radius of the Earth. Chapter One of “The Earth” discusses the scientific method to achieve a viewpoint that is more aligned with reality than before. The process can be described as: defining the problem‚ collecting information

1 Metallogeny: The rationale behind space (WHERE?) – time (WHEN?): distribution of ore deposits Whether there is any globally discernible unifying pattern about the space-time distribution pattern The exclusivity in spatial-temporal distribution of ore deposits is a tangible proposition Such distribution patterns are REAL and not apparent (not artifacts due to inadequate sampling) Such patterns can be explained in the light of the known/emerging facts about the evolution of the planet

Chapter 32 – An Introduction to Animal Diversity All animals share a common ancestor‚ sponges are basal animals‚ eumetazoa is a clade of animals with true tissues‚ most animal phyla belong to the clade bilateria‚ and vertebrates and some other phyla belong Animals share a unique homeobox-containing family of genes‚ known as the Hox genes‚ suggesting that this gene family evolved in the eukaryote lineage that gave rise to animals. Hox genes play important roles in the development of animal embryos
