WebView Answer. Where on Earth does magma (a) cool slowly, (b) cools rapidly, and (c) cools instantaneously? View Answer. Igneous rocks are composed of primary minerals, sedimentary rocks mostly of secondary. What is the significance of this with respect to relative stability under chemical weathering conditions? WebMagma is produced at convergent boundaries and rises toward the surface, where it can form magma bodies in the upper part of the crust. Such magma bodies, at temperatures of around 1000°C, heat up the surrounding rock, leading to contact metamorphism (Figure 7.19). Because this happens at relatively shallow depths, in the absence of directed ...
