Name jack laber GEOL 1010 Section 002 Homework Assignment 1 Due Date September 2 2021 11 59PM Part I What is the Rock Cycle On the diagram below complete the rock cycle flow chart using arrows to show how each material product in the boxes transforms from one to the other The different processes are listed on page 2 Some processes on pp 2 are missing definitions which you will be filling in in Part II In other words what process turns magma into igneous rock Think of ALL the processes that can occur If you can use a different color for each rock type and process see pp 2 draw arrows between the products to represent the processes Label the arrows with the appropriate process es using the text function Don t forget the transformations or processes that result in the same product 15 points Red melting Blue cooling Pink heat pressure Black erosion weather Purple cementation Magma Metamorphic Rock Igneous Rock Sedimentary Rock Sediment 1 Name jack laber Part II Definitions Please fill in the missing definitions You can fill in the table or use the next page 5 points Process es Textbook pg BURIAL deep BURIAL shallow CEMENTATION Chapter 5 COMPACTION Ch 5 CRYSTALLIZATION Chapter 4 DEPOSITION ERUPTION Chapter 4 EROSION Chapter 5 EXHUMATION MELTING Chapter 4 METAMORPHISM Chapt 6 SUBDUCTION Chapt 9 WEATHERING Chapt 5 What happens Rocks are buried by the deposition of younger overlying rocks or by plate tectonic processes Associated with METAMORPHISM Rocks are buried by the deposition of younger overlying rocks Associated with COMPACTION and CEMENTATION Define the binding together of particles or other things by cement The deposition of rock layers above puts pressure on deeper sediments causing the grains to be pushed closer and closer together and reducing pore space between sedimentary grains Define the process in which crystals are formed either from something that has been melted or from a solution Sediments cease moving and are buried by other sediments Magma erupts into the atmosphere or water at Earth s surface transforming into solid igneous rock Elements and molecules in the magma combine into distinct mineral crystals Define the process of eroding or being eroded by wind water or other natural agents Solid rocks formerly buried deep under the Earth s surface are brought to the surface by the removal of overlying rocks Define becoming liquified by heat Increased heat and or pressure associated with DEEP BURIAL and or contact with hot magma Rock is NOT melted but elements and molecules can recombine to form new minerals while the rock remains in a solid state Define the sideways and downward movement of the edge of a plate of the earths crust into the mantle beneath another plate Breakdown of rocks at the Earth s surface into smaller fragments of the same composition and or chemically altered into different minerals or elements and molecules all called sediments 2 Name jack laber Definitions Only fill in the table on page 2 or use this page Cementation Crystallization Erosion Melting Subduction 3 Name jack laber Part III A Layers of the Earth Please fill in this table about the major chemical layers of the Earth for chemical layers only the chemical composition matters not whether its solid or liquid Go in order from the center to the surface or vice versa when completing the table State one additional fact observation or characteristic about each major layer 9 points Layer 1 Mantle Composition Additional Fact Observation The mantle makes up about 84 of earths volume The deepest areas of earths crust are located in mountainous areas Earth s core is very hot due to frictional heating Magnesium Iron Oxegyn Calcium Aluminum silicon Oxegyn Silicon Aluminum Iron calcium Iron Nickel 2 Crust 3 Core Geosphere Lithosphere Mesosphere Asthenosphere B What are the major physical layers of the Earth for physical layers the layers are differentiated by strong or weak solid or liquid state density 3 points 4 Name jack laber Part IV General Questions 1 State two differences between the oceanic crust and the continental crust Expand in 1 or 2 sentences on one of those differences 5 points The oceanic and continental crusts have very different thickness s the oceanic crust is about 5 10 km thick whereas the continental crust is 30 50 km thick This id due to the plate boundaries in the oceanic crust usually being destroyed 2 List the geologic eons from youngest to oldest 2 Phanerozoic Proterozoic Archean hadeon 3 In what geological era do we live 1 We live in the Holocene era 5
