marcasite 4. Distinguish between a rock and a mineral i.e.‚ what are they? How are they similar? How are they different? A rock is a solid mineral formed on the surface of the Earth. A mineral is a natural solid substance (i.e. mountains). They both are solid substances and are both natural substances. Also‚ they both are chemical compositions and both make up the Earth. Minerals are natural occurring inorganic solids and have a specific chemical formula. A rock is made of one or more minerals. 5

the hot lava fragments and clouds of dust erupting from Vulcano came from Vulcan’s forge as he beat out thunderbolts for Jupiter‚ king of the gods‚ and weapons for Mars‚ the god of war. 2. What is the difference between magma and lava? •Molten rock below the surface of the Earth that rises in volcanic vents is known as magma‚ but after it erupts from a volcano it is called lava 3. What are the main types of volcanoes? •cinder cones‚ composite volcanoes‚ shield volcanoes‚ and lava domes.

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

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

fine-grained metamorphosed shale rock‚ usually gray to black in color. Mineral composition in variable but is usually made up of some combination of equidimensional mosaic of quartz or calcite along with inequidimensional sheet silicates in random orientation or sometimes containing andalusite porphyroblasts. OCCURANCE Hornfels forms when shale rocks come into contact with a hot igneous intrusion body at lower pressures and at the equilibrium temperature of the igneous-country rock contact. TYPES Hornfels

Someting About Feldspar Crusher Feldspar will be the most common rock forming mineral. Feldspar occurs in igneous‚ metamorphic and sedimentary rocks and consequently could be observed all through the state. Applications of feldspar Feldspar is used to create dinnerware and bathroom and creating tiles. In ceramics and glass production‚ feldspar is used as being a flux. A flux can be a material that lowers the melting temperature of another materials‚ in this case‚ glass. The feldspar crusher

Canyon is a big mystery. What we can say‚ is that its rock layers give us clues of how tectonic erosion occurred in the Grand Canyon. Some of those rocks can be age determined‚ but some can’t. Some of the rocks that can be age determined are the igneous rocks‚ and those rocks that can’t be age determined are the metamorphic rocks. The igneous rocks are one of the three main rocks. The metamorphic rocks arise from the transformation of existing rock types‚ which make changes due to heat and pressure
