The mean angle is all the angles added up together then divided by how many angles they were. For example:
I have four angles 44°, 37°, 29° and 67°, what I would do is add them all up together, i.e, 44+37+29+67, which equals to 180. Then I would divide 180 by how many angles they were, so I would do 180÷4 which equals to 45. So the mean angle would be 45°, that's how you find the mean, hope that helps.
Plate tectonics is a term used to describe how the plates or slabs are formed as a result of faults and folds created within the earth surface and this term also used in describing how the earth was formed due to the impact of large solid objects from the outer space and the removal of gas due to the SolarWinds.
The mantel that is composed of three layers and the top of them being the asthenosphere on which Alfred Wegener gave evidence that the terrestrial plate floats freely on these with less resistance offered by SIMA.
The puzzle evidence also suggested by him was about the same theory that made the large supercontinents in existence and from which the later land masses broke off to form Pangea and Gondwanaland.
Later on much-studied were conducted in this tic to test its validity and found that the continents were truly displaced due to the spreading of the oceanic floors due to the mid-oceanic ridges and these accounts for 99% of the oceanic crustal masses. It was only possible through the deep exploration of the paleomagnetism and chain of rocks of various ages.
Many Native Americans in the Great Lakes–St. Lawrence Lowlands planted various crops such as maize. The correct option among all the options that are given in the question is the second option or option "B". I hope that this is the answer that you were looking for and the answer has come to your desired help.
Flows are a mixture of water, rock and sediment. They move very quickly. A slide happens when a section of soil or rock suddenly gives way and moves down a slope. The material moves as a single mass along a slippery zone.
