Why does a higher temperature cause the viscosity of a magma to decrease? A. in minerals that form at high heat, silica tetrahedra share fewer (or no) links with other tetrahedra, leading to fluid melts
B. heat increases bonding in a magma causing the atoms to resist moving past one another
C. heat causes the magma to dissolve in water, meaning it can flow easily like a river of water

An ionic compound can conduct electricity when a it is dissolved in water b its crystals are ground into powder c it is in solid form d it is heated to just below its melting point

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length of a column of water 1.00 km high for a temperature increase of 1.00ºc. note that this calculation is only approximate because ocean warming is not uniform with depth.
