ERS120H5 Lecture Notes - Lecture 4: Isostasy, Mid-Ocean Ridge, Mariana Trench
Document Summary
O/c - trench and a volcanic ridge - the andes. The continent begins to pull apart and the crust is thinned and a valley forms. Divergent - plates move away from each other - c/c or o/o or o/c. Convergent - plates move toward each other - c/c or o/o. Transform - plates move past each other - c/c. Name and define the three types of plate boundaries (divergent, convergent, transform) and whether they can occur between ocea(cid:374) ocea(cid:374), ocea(cid:374) co(cid:374)ti(cid:374)e(cid:374)t and/or co(cid:374)ti(cid:374)e(cid:374)t co(cid:374)ti(cid:374)e(cid:374)t. Recognize the different types of plate boundaries (e. g. tra(cid:374)sfor(cid:373)/co(cid:374)ti(cid:374)e(cid:374)t continent or co(cid:374)(cid:448)erge(cid:374)t/ocea(cid:374) continent, etc. ) from the distribution of earthquakes, volcanoes, topography and age of the ocean flo or. (i. e. tutorial 1) Explain some of the different features found at ocea(cid:374) ocea(cid:374), ocea(cid:374) co(cid:374)ti(cid:374)e(cid:374)t and co(cid:374)ti(cid:374)e(cid:374)t continent convergent zones (trench, volcanic arc, mountain range). O/o - volcanic arc - mariana trench & islands in between japan and australia.
