Answer: none


Question: Process:  -Rock begins as magma from a volcano -The magma cools -Crystals form and the magma become igneous rocks -The igneous rocks break down into sediment -Become sedimentary rocks -If subjected to heat and/or pressure from plate-tectonic activity the sedimentary rocks become metamorphic rock -The metamorphic rocks melt -Become magma again.
 Question: What is the effect of less hard plant parts replaced by minerals on less igneous rock forming.?

Answer: none


Question: Process:  -Greenhouse gases are released into the air by human activities -The earth changes energy from the sun into heat -Heat rises from the ground -Greenhouse gas molecules in the atmosphere prevent the heat from going into space -The temperature of the earth increases -The temperature continues to rise and melts the polar ice caps -The temperature rises even faster.
