Scenery You Need to Know You Need to Know What is Geological Time What is geological time and what does it look like Where does carboniferous limestone granite and chalkclay fit in to it WHAT IS THE DIFFERENCE BETWEEN AN ERA AND A PERIOD. “Liquid Hot Magma!”. Igneous Rocks. Rocks formed from cooling of lava or magma. Lava-Melted rock erupted from volcanoes and deposited on the earth’s surface. Cools quickly.. Magma-Melted rock that sits inside the earth in a magma chamber. Cools slowly.. Sedimentary rocks cover ~ 75% of Earth’s surface. ~ 5 % (by volume) of Earth’s outer 10 miles. Contain evidence of past environments:. Important resource. Coal, oil, and other fossil fuels. Groundwater resources. Chemical Sedimentary Rocks. . Limestone. Chert – Silica. Evaporites. Organic Rocks. Coal. Oil and natural gas. Clastic Sedimentary Rocks. Formed from clasts (bits and pieces of pre-existing rocks) transported, deposited,and lithified. UNIT . - . 6. What is Metamorphism. Metamorphism. (from the Greek words for “changing form”) is the process by which rising temperature and changes in other environmental conditions transform rocks and minerals. GLY 2010 - Summer 2016 - Lecture 11. 2. Metamorphism. The mineralogical, chemical, and structural adjustment of solid rocks to physical and chemical conditions. 3. Metamorphic Rock. Any rock derived from pre-existing rocks by mineralogical, chemical, and/or structural changes, essentially in the solid state . Bell ringer: . Looking at the pictures, what do you think metamorphic rocks are? . What are Metamorphic Rocks? . Metamorphism means “to change form”.. Metamorphic rocks are rocks that form when . Color . Texture. Light. Dark. Fine. Coarse . Igneous rocks are classified according to their. . origin. , . texture. , and . mineral composition. .. Origin . D. id it harden inside the earth or on the earth’s surface?. Rocks are classified by how they are formed, their composition, and texture. Rocks change over time through the rock cycle. TYPES OF ROCKS. ROCKS ARE DIVIDED INTO THREE GROUPS BASED ON HOW THE ROCKS . What are minerals?. Common rock-forming minerals. Physical properties of minerals. Basic rock types. The rock cycle. Minerals . Natural . Solid. Atoms arranged in orderly repeating 3D array: . crystalline. Sedimentary rocks form in 1 of 3 ways:. 1. . Clastic. Sedimentary Rocks- made of pieces and grains of other rocks. Material such as . sand . or . mud. -usually deposited in . water. Conglomerate sandstone. Standards:. S6E5b. Investigate the contribution of minerals to . rock composition.. S6E5c. Classify rocks by their process of formation.. S6E5d. Describe processes that change rocks and the . http://www.youtube.com/watch?v=aCnAF1Opt8M. 1. What are the building blocks of rocks? . 2. How are rocks classified?. 3. What are the parts of a volcano?. Magma chamber. vent. Crater. sill. Magma conduit. . Chemical Sedimentary Rocks. In contrast to detrital rocks, which form from the solid products of weathering, . chemical sediments . derive from ions that are carried in solution to lakes and seas. . River erosion. River erosion also happens by the load carried on the river channel itself.. The erosion rate varies with different volume and velocity.. C. orrasion (abrasion). A. ttrition. S. olution (corrosion).
