Gneous rock is formed by the cooling and solidification of molten earth materials. igneous rock forms when magma or lava cools. if underground pockets of magma and solidify, igneous rock is formed, such as granite. a) cools quickly, extrusive b) cools quickly, intrusive c) cools slowly, extrusive d) cools slowly, intrusive

The answer is d. Igneous rocks is indeed formed through the cooling of molten lava on the surface, making extrusive igneous rock. However, if those underground pockets of magma were to cool underneath the surface, because of its force to, it will still form intrusive igneous rock, slowly cooling.

he would use the colour black

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
