Question

I'd like you to answer question 4 only, but you need question 3. So, I attached a picture of the question and the answer for question 3.

Please answer all parts for question 4 and as soon as possible.

would expect northern since the lat and long are positive. At 30 degrees near equator (90)so v is fast at 50 near pole (0) so v is slow from 30 to 50 it’s decreasing, so the Atlantic spreading is decreasing.

Using v = omega * R * sin(theta)

When theta is at 0 v is 0, 90 is Rw, 180 0, and 270 is Rw again, So if it was from 50 to 30 the atleantic spreading would increase.

Please answer Q 4, and if you thought something good would help with my answer in number 3 please add.

3(20%) Determine the pole for Eurasia with respect to North America. Would you expect the pole to be in the northern or southern hemisphere (explain why)? Would you expect the width of the Atlantic ocean to increase or decrease from 30 to 50 degrees north latitude. Why? 4. (10%) What significance is there in assuming that plates act as rigid bodies when calcualting relative plate velocities? What may result if this assumption is not true? (For example, what effect might extension and/or transtension in the Basin and Range have on your answer to part

Explanation / Answer

4- Relative plate velocities are the velocities of tectonic plates with respect to other plates. Mostly due to seafloor spreading and the magnetic polarity reversal of the materials coming out of the spreading zone, we may come to know of the spreading amount. If we do not assume plates to be rigid bodies then we won't come to know of the extension amount of the seas through seafloor spreading since in non-rigid bodies other types of forces such as shear also come to play.
