Q. What are the processes involved in the formation of rocks?
The key processes of the rock cycle are crystallization, erosion and sedimentation, and metamorphism.
Q. What are the processes involved in the transformation of igneous rocks to sedimentary rocks?
Igneous rock can form underground, where the magma cools slowly. Or, igneous rock can form above ground, where the magma cools quickly. When it pours out on Earth’s surface, magma is called lava. After a long time the sediments can be cemented together to make sedimentary rock.

Q. What are the processes and products of the rock cycle?
The three main rock types are igneous, metamorphic and sedimentary. The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation. Any rock can transform into any other rock by passing through one or more of these processes. This creates the rock cycle.
Q. What is a rock-forming and give three examples?
Rocks are composed of minerals. There are almost 5000 known mineral species, yet the vast majority of rocks are formed from combinations of a few common minerals, referred to as “rock-forming minerals”. The rock-forming minerals are: feldspars, quartz, amphiboles, micas, olivine, garnet, calcite, pyroxenes.
Q. What are the major rock-forming types?
There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming—that are part of the rock cycle. Sedimentary rocks are formed from pieces of other existing rock or organic material.
Q. What are the two most common rock-forming mineral groups?
The roughly 1,000 silicate minerals make up over 90% of Earth’s crust. Silicates are by far the largest mineral group. Feldspar and quartz are the two most common silicate minerals. Both are extremely common rock-forming minerals.
Q. Which two elements are found in all silicate minerals?
General structure A silicate mineral is generally an ionic compound whose anions consist predominantly of silicon and oxygen atoms.
