The Rock Cycle & Classification of Rocks The rock cycle is the formation‚ breakdown and reformation of a rock as a result of sedimentary‚ igneous‚ and metamorphic processes. The rock cycle is an illustration that is used to describe how the three rock types are related and how Earth processes change a rock from one type to another over time. Each group contains a collection of rock types that differ from each other on the basis of the size‚ shape and arrangement of mineral grains. Due to the driving

Formation of Rocks The three main ways rocks are formed: • Sedimentary rocks are formed through the gradual accumulation of sediment: for example‚ sand on a beach or mud on a river bed. As the sediment is buried it is compacted as more and more material is deposited on top. Eventually the sediment will become so dense that it is essentially rock. This process is known as lithification. • Igneous rocks are rocks which have crystallized from a melt or magma. The melt is made up of various components

About the Igneous rocks: The Igneous rocks are the oldest type of rocks among all. The word "Igneous" comes from a Greek word which means fire. In the deepest part of the Earth‚ the minerals are found in a liquid form‚ which is known as magma. When the magma pushes towards the surface of the Earth‚ it starts to get cool and converts into the solid Igneous rocks. The formation of Igneous Rocks: The Igneous rocks are known as the fire rocks and these are generally formed underground or above the

Igneous Rocks Igneous rocks originate from deep within the Earth’s crust. Igneous rocks (from the Greek word for fire) are formed when magma crystallizes and solidifies. An increase in temperature‚ a change in the composition‚ or decrease in the pressure can cause melting of these rocks in the mantle which form igneous rocks. The melt begins deep below the surface of the Earth close to active plate boundaries. As the temperate increases the rocks rise toward the surface. Igneous rocks are divided

The Big Rocks of Life! One day a wise teacher was speaking to a group of his students. He pulled out a one-gallon‚ wide-mouthed mason jar and set it on a table in front of him.

When the jar was filled to the top and no more rocks would fit inside‚ he asked‚ "Is this jar full?" Everyone in the class said‚ "Yes." "Really?" he asked. "Let’s see." He reached under the table and pulled
