Continental Drift, the theory that continents move slowly about the earth's surface, changing their positions relative to one another and to the poles of the earth. In the past the theory has been discussed but not generally accepted, most geologists believing the continents to be fixed in place and subject only to vertical movements, such as those observed during mountain uplift. In recent years, however, a sound body of evidence in support of a modified form of the drift theory has been found.
to prove that his theory of “Continental Drift” could have been true. The continental drift explained how parts of Earths crust could slowly drift atop a liquid core causing all continents were once formed as a single landmass to split apart . Although Wegener was the not the first scientist that all continents were connected at some point of time but, he was the first to prove it was plausible with evidence. This is why I agree that the continental drift is true, because of the fact that there were
Alfred Wegener was a meteorologist and astronomer. He was the first scientist to introduce the theory of the continental drift. Wegener theorized that at one time the continents were one large landmass or Pangaea that had drifted apart. His ideas were initially rejected by other scientists. It was not until long after Wegener’s death that proof was obtained and his theory verified. The Life of Alfred Wegener Alfred was born in Germany in 1880 and led a very busy life. He received a PhD in astronomy
To determine how groynes prevent longshore drift. The issue: Longshore drift influences the deposition and erosion of sediments. Waves erode the coast and transport the eroded material along the coastline. Over a period of time, the material will be deposited on a beach or form a larger feature such as a spit. Groynes are structures built at equal intervals along the coastline. Their purpose is to restrict longshore drift, preventing coastal erosion. Figure 1 - Google Maps About the location:
To Test if Longshore Drift is Taking Place Along Deal Beach on the Day of Our Visit For this aim, we measured the wave angle. To do this, I laid a protractor on the floor, and watched for about 5 minutes in which direction the waves were travelling. I would look down on the protractor, and note down the angle of the waves. I then worked out the average angle. We had to do measure the wave angle because it would show us in which direction the longshore drift (if any) was taking place
Sea The purpose of this aim is to see the effects of Longshore Drift over a longer period of time. Theory Work Groynes are structures that extend finger like, perpendicularly from the shore. Usually constructed in groups called groin fields, their primary purpose is to trap and retain sand, nourishing the beach compartments between them. Groynes initially interrupt the longshore transport of littoral drift. They are most effective where longshore transport is predominantly in
school, not himself and has the time of his life. Their view changes in an instant once they enter the major leagues. Baseball suddenly converts from a sport based on fun and teamwork to the focus on money and yourself. The ethics in baseball just drift away once this switch occurs and everything has changed. How exactly do the ethics just d...
Education Department School: an educational institution which provides primary or secondary education on a full-time daily basis, or by radio or correspondence Over the past decade there has been a enrolment drift in education from public schools to private schools. In the year 2001 this enrolment drift has continued. In 1980 there were 78% of all students in public education, but last year there were less than 69%. There are a total of 2 248 275 students in public schools (ABS 12/02/2001). While Australia
distinct avenue when a linear direction does not suffice to express these multi-variable musings. It is easier to float in the sea of my unarticulated thoughts than to build a language boat and sail on a definite course, but in allowing myself to drift at the whim of my mind's currents, I get nowhere. In articulating myself, I create a solid manifestation to which I can look and say, "That's what I believe." I may not define my feelings poorly when I leave them unspoken, but in refusing to
nitrogen oxide, and ozone ( SOý, NOx, and Oý ) is released into the air. These chemicals are absorbed into clouds and results in Acid Presipitation ( Acid Rain, Acid Snow, Acid Hail, Acid Sleet ). When the chemicals aren’t absorbed into clouds, they can drift for miles and fall to the ground, resulting in Acid Deposition, or dry deposition. When Acid Rain falls into water it is mixed in with the normal water and causes the pH of the entire body to be raised. Measurments on the pH (potential Hydrogen )
