Solar System Formation – Earth Formation Layers of the Earth Review The force of attraction between two objects Accretion solar wind gravity The clumping together of smaller gas and dust particles into larger objects Accretion Solar wind Gravity A stream of charged particles from a star Accretion Gravity Solar wind Nebula formed from a supernova and contains heavier elements Terrestrial Nebula Gaseous Nebula Solar Nebula Earth-like planets made of heavier elements and compounds located closer to the sun Terrestrial Planets Gaseous Planets Solar planets Planets consisting of lighter elements located further from the Sun Terrestrial planets Gaseous planets Solar planets Mineral compounds made of silicon and oxygen that make up most of the inner planets crust Carbonates Silicates oxides Left over frozen gaseous debris where dwarf planets are found Kuiper Belt Oort cloud Asteroid belt Outer boundaries of the Solar System where comets form Kuiper Belt Oort cloud Asteroid Belt Region between Mars and Jupiter containing irregular shaped objects Oort Cloud Kuiper Belt Asteroid Belt Layers of the Earth Which layer is a solid ball due to high pressure? A. THE CRUST B. THE MANTLE C. THE INNER CORE D. THE OUTER CORE Which layer is Earth’s Outer Rocky Surface? A. Inner Core B. Outer Core C. Crust D. Mantle Which layer is semi molten and sits underneath the crust? A. Inner Core B. Outer Core C. Crust D Mantle Which layer is responsible for Earth’s Magnetic Field? A. Inner Core B. Outer Core C. Crust D. Mantle Ocean Crust is made of Granite Basalt Oxygen Silicate Continental Crust is made of Granite Basalt Oxygen Basalt Which is more dense? ocean crust continental crust Both are the same Inner planets are _____ than outer planets A. Less dense, refractory and hotter B. More dense, volatile and cooler C. More dense, refractory and hotter D. Less dense, refractory and hotter Solar winds caused A. Less dense material to be blown farther B. More dense material to be blown farther Inner planets have Cores of silicate rock and iron/nickel crust Cores of granite and silicate rock crust Cores of iron/nickel and silicate rock crust Outer Planets have Cores of silicate rock and crust of silicates Cores of gases and layers of granite Cores of silicate and layers of gases True or False The asteroid belt lies between Mars and Saturn The Oort cloud is close to Neptune The Kuiper Belt contains Dwarf planets The Kuiper Belt is closest to Neptune Comets originate from the Oort Cloud The iron catastrophe was responsible for Forming volcanoes Forming the core Forming water on the surface Which Planets were formed by gravity Inner planets Outer planets Which planets are cooler / lower melting points? Inner Planets Outer Planets Order of Earth Formation first 5 events Solar nebular, accretion, bombardment, iron catastrophe & radioactive elements Solar nebula, accretion, bombardment, radioactive elements & iron catastrophe Solar nebula, bombardment, accretion, iron catastrophe & radioactive elements Order of Earth formation, last 5 events Crust forms/ surface water, magnetic field forms, planetesimal hits earth, volcanoes form, moon moves away. Magnetic field forms, volcanoes form, planetesimal hits earth, moon moves away & crust forms /surface water Magnetic field forms, planetesimal hits earth, volcanoes form, moon moves away, crust forms/surface water Minerals – T or F Man-made Organic Can be solid or liquid Definite crystal structure Definite chemical composition The greatest percentage class of minerals in the crust is Oxides Carbonates Silicates Rock formed from magma Igneous Metamorphic Sedimentary Rock formed from the layering and cementing of sediments over time Igneous Metamorphic Sedimentary Any rock type that undergoes great pressure and heat Igneous Metamorphic Sedimentary How can rocks change over time? Discussion How do rocks recycle – why do we call how rocks form the rock cycle? Discussion
