| What is in the nucleus? | Protons and neutrons |
| What charge does the proton have? | Positive charge |
| What charge does neutrons have? | Neutral charge |
| What charge does electrons have? | Negative charge |
| What is atomic mass? | The number of protons plus neutrons |
| What do electrons do? | Electrons move AROUND the nucleus |
| What are the four layers of Earth? | Mantle, Outer core, Inner core, and the Crust |
| What are the four layers of earth from outer to inner? | Crust, Mantel, Outer core, Inner core |
| What are the four layers of earth from thickest to thinnest? | Mantel, Outer core, Inner core, Crust |
| Why does the crust float on the Mantel? | Because it is less dense |
| What is the crust? | Earths surface and continental/oceanic plates:where we live |
| What is the Mantel? | Molten rock |
| What is the Outer core? | Liquid nickle and iron |
| What is the inner core? | Solid nickle and iron |
| What are the two classification systems scientist use to describe Earths interior? | Compositional and Physical |
| What is compositional? | Materials that make up each layer of Earth |
| What is Physical? | State of matter and temperature of each layer of the Earth |
| What are the four Earth systems? | Geosphere, Hydrosphere, Atmosphere, and Biosphere |
| What is the Geosphere? | Earths surface and interior |
| What is the Hydrosphere? | All water on Earth |
| What is the Atmosphere? | Layer of gasses around Earth |
| What is the Biosphere? | All living things on Earth |
| How do Geologist know about the earths interior? | Seismic Waves |
| What is Mechanical Weathering? | Physical break down of rocks and minerals |
| What are some examples of Mechanical Weathering? | roots breaking rook, water freezing and expanding to break rock |
| What is Chemical Weathering? | Chemically break down or rocks and minerals |
| What are some examples of Chemical Weathering? | acidic water dissolving rock |
| What is erosion? | Transport of weathered materials |
| Examples of erosion | Carving a canyon by running water, formation of underground caverns by water, landslides |
| What are the soil layers called? | Horizons |
| What are the layers of soil from top to bottom? | Topsoil/horizon A, Subsoil/horizon B, Bedrock/horizon C |
| Which horizon is rich in humus? | Topsoil/horizon A |
| What determines what minerals are in soil? | The parent rock/bedrock |
| What is soil made up of? | Minerals, water, air, and organic mater |
| What are minerals made up of? | Crystals |
| What are rocks made up of? | Minerals |
| What are the Mineral Characteristics? | Hardness, luster, streak, cleavage/fracture, and density |
| What are the three types of rocks? | Igneous Rocks, Sedimentary Rocks, and Metamorphic Rocks |
| How is an Igneous Rock formed? | When magma or lava cools and hardens |
| How is a Metamorphic rock formed? | Through heat and pressure |
| How is a Sedimentary Rock formed? | Weathering and erosion and then compaction and cementation |
| Can all rocks turn into any form of rock? | Yes |
| What are Topographic map? | A map elevation that shows |
| What does it mean when the contour lines and close together? | That is a steep area |
