from pre existing rocks‚ they collect and undergo a process called lithification‚ then form layered rocks The crust of the earth is largely covered up with sedimentary rocks When sedimentary rocks melt they become magma. Magma can undergo crystallization‚ forming igneous rocks (intrusive or extrusive) The igneous rocks may encounter rain and start to break apart and become sediments. Metamorphic rocks are formed by igneous or sedimentary rocks Granite is a: intrusive igneous rock Limestone is

making up parts of 6 provinces and 2 territories. The Canadian Shield is the largest landform region in Canada. Physical Landscape The Canadian Shield is made up of metamorphic and igneous rock‚ containing some of the world’s oldest rocks. It had once been a major mountain region but it is now relatively flat with rounded rock hills. In addition‚ hundreds of thousands of lakes existed as gouging and scrapings of ice many years ago which had left depression in the bedrock. The Canadian Shield lakes are

chemical and structural adjustments in solid rocks to physical and chemical conditions which have been imposed due to changes in pressure and temperature or both. Metamorphism occurs below the surface zones of weathering and cementation. Conditions of metamorphism differ from the conditions under which the rocks in question were originally formed. Metamorphism produced as a result of the progressive increase in temperature and pressure‚ i.e. by burial of a rock within the earth‚ is termed prograde metamorphism

our planet over time through rocks. Rocks are divided into three major classifications; • Igneous- rocks created by volcanism and the cooling/ crystallization of magma. • Sedimentary- rocks created by the compaction and cementation of sediment created by the weathering of pre-existing rocks of igneous‚ metamorphic or sedimentary origin. • Metamorphic- rocks that are formed by metamorphosing pre-existing rocks through heat and pressure. Metamorphic rocks can be made from any of the

Professor Roberlyn Cabrera DETERMINING ROCK TYPE I. Introduction: A rock is a naturally occurring solid aggregate of one or more minerals or mineraloids. For example‚ the common rock granite is a combination of the quartz‚ feldspar and biotite minerals. The Earth’s outer solid layer‚ the lithosphere‚ is made of rock. Rocks have been used by mankind throughout history. From the Stone Age rocks have been used for tools. The minerals and metals we find in rocks have been essential to human civilization
