Earth’s history. The theory was first proposed by Alfred Wegener in 1912. Whilst his general idea of continental movement eventually became widely accepted‚ his explanation for the mechanism of the movement has been supplanted by the theory of plant tectonics. However there was a problem in accepting this idea originally because Wegener had no convincing mechanism or solid evidence for how the continents might move. Wegener had originally thought that the continents were through the surface of the

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

Being so close to an active volcano poses many risks to communities. Even though Mount St. Helens erupted over 30 years ago we know that it is still an active volcano. Future eruptions can kill and injure entire communities. Since the eruption in May of 1980 of Mount St. Helens‚ geologists have come to a better understanding of both the mechanics of volcanoes and the dangers they present to the environment and communities. Did you know that volcanic ash is actually small glass particles? Or that

RF #1 The name Lucifer has often been understood to be another name for the devil or the satan. This identification has a long history in the church‚ going back to at least the fourth century. Its origin is actually from a passage in the Old Testament from the book of Isaiah that‚ to some‚ speaks of a being cast out of heaven because of pride. Since some people see a reference to the devil being cast out of heaven in the New Testament (Rev 12:9-12; cf. Lk 10:18)‚ they assumed that the Isaiah passage

kimberlite and lamproite pipes that diamond seekers look for. Natural diamonds require very high temperature and pressure. This is not present globally. It is thought to be present primarily in the mantle beneath the stable interiors of continental plates. Diamonds are stored in these “diamond stability zones”. “This type of volcanic eruption is extremely rare and has not occurred since scientists have been able to recognize them” (Geology.com). The second process is diamond formation in sebduction

Assignment: Earthquake Part A: 1. Earthquakes are the sudden and rapid shaking of the earth. The collision of tectonic plates and volcanic eruptions are what cause earthquakes. 2. Earthquakes are caused by the movement of tectonic plates and by volcanoes. The Earth’s crust is made up of plates which can freely slide across the mantle. When these plates collide or slide past with other plates‚ earthquakes occur. After the main earthquake‚ an aftershock may occur as the rock masses settle down in new

Continental Drift‚ why True? Continental drift is the process of large mass of land and rocks unceasingly moving for a long period of time‚ which can be explained by what is called "Plate Tectonics". Due to the fact that continental drift is a theory‚ there is evidence and other sets of statements to back it up. According to Wegener‚ a geologist stated that segments of the Earth has made continental drift true (possible) whilst other pieces of information supported that continental drift has happened

2008) The Galapagos Islands are roughly 4 million years old. Submarine volcanoes built up these islands over a period of time. There are a couple of theories as to how these islands were formed. The hot spot theory and the Tectonic plate theory. It is believed that plate tectonics are responsible for the formation of the Galapagos Islands.
