What are some flaws in Alfred Wegener’s Continental Drift Theory?

/in /by

Wegner had the basic idea correct, but what he couldn’t explain was a mechanism for why plates shifted around.

Because he could not explain a mechanism that would cause the Earths’ crustal plates to shift around, his idea was dismissed at the time. He also had rates of movements for his continents that seemed very unlikely – too high. It took another 50 or more years for the current plate tectonic theory to become accepted by geologists. This was the result of more evidence being found, including the idea of mantle convection plumes that drive plate movement.

Many People are quick to dismiss global warming after a cold winter or a late summer.After watching the video how would you respond to this person? Why is it difficult to base climate on a single seasons weather? Use the data and examples to support your answer. (Base your desesion on what you have learned from the video and textbook reading. It’s not meant to be a discussion of political ideology.

If Two loudspeakers are placed at either end of a gymnasium, both pointing toward the center of the gym and equidistant from it. The speakers emit 266 Hz sound that is in phase. An observer at the center of the gym experiences constructive interference. The observer must walk toward either speaker the distance of 0.322 m to first experience destructive interference.

Calculate the distance to the first position of destructive interference if the frequency emitted by the speakers is lowered to 230 Hz .

Chapter 4 Plate Tectonics and Earthquake

1.In 100 to 200 words: Describe common hazards that follow major earthquakes in cities.

2. In 200 to 400 words: What factors combined to cause the resonance in México City that was so deadly in the 1985 earthquake? How far was the city from the epicenter? Two days after the earthquake, the city was shaken by a magnitude 7.5 earthquake. Would you consider this a main-shock and an aftershock or twin earthquakes?

Chapter 5 Earthquakes Throughout the U.S. and Canada

3. In 100 to 200 words: Describe how Great Shakeout Events help to prepare communities.

4. In 200 to 400 words: Discuss key facts and critical issues associated with the New Madrid fault. What are the potential impacts of an earthquake occurring in this area and what can we do today to mitigate?

5. In 100 to 200 words: In your opinion, is it appropriate for the government to disallow the growth and development at the base of volcanoes that may erupt? Defend your viewpoint. If you think it is appropriate, how might the government proceed? If you think it is not appropriate, what could the government to in effort to prevent the loss of life/property in the case of an eruption?

Chapter 7 Volcano Case Histories: Killer Events

How far away is pluto from earth? Does this distance vary?

/in /by

It varies. The average distance is nearly the average distance of Pluto, from , 5906.4 million km = 3670.2 M miles. Interestingly this average is the same, for every other inner planet.

The distance between an inner planet and outer planet varies from (outer perihelion – inner aphelion) and (outer aphelion + inner perihelion), nearly. The average is as stated in the answer.. The error in this approximation due to the inclination 17.2 deg of Pluto’s orbit to ‘s orbit might change the lower sd (lsd), beyond the 5th (4 here) sd. For mathematical exactitude, this inclination has to be considered for getting more than five sd.
