Document Summary
Match the three major types of plate boundaries to the motion at those boundaries. The edges of the plates slide past each other - transform plate. The plates are moving away from each other at mid-ocean ridges. The plates are colliding with each other, and oceanic plates subduct under continental plates. Question 3: which of these will cause a rock to melt (lower the melting point)? (select 3 answers, decrease in temperature with pressure remaining the same. Increase in temperature with pressure remaining the same: decrease in pressure with temperature remaining the same. Increase in pressure with temperature remaining the same: low/no water content, high water content. Question 4: seismic waves are used to determine that the interior of the earth is divided into layers of rock with different properties. Seismic waves will stop or slow down depending on the density of the material they"re traveling through.
