Final Exam Review
Question | Answer |
---|---|
Solid, form in nature, crystal, made of same ingredients, inorganic | Characteristics of minerals |
Chemically changes rock - rusting and dissolving | Chemical Weathering |
Occur in the mantle and cause plate motion | Convection Currents |
Plates push together. Forms: mountains, volcanoes, island, trenches | Convergent Boundary |
Forms as sediments are deposited at the mouth of a river | River Delta |
Plates move apart. Forms: mid ocean ridge, rift valley | Divergent Boundary |
Transport or movement of rock or sediments | Erosion |
Mesosaurus fossils found in S. America and Africa, tropical plants fossils found in Greenland, continents fit together like a puzzle | Evidence of continental drift |
Rocks form from lava that cools outside Earth | Extrusive Igneous |
by the process of how they form | How are rocks classified? |
Forms from the cooling of magma | Igneous Rocks |
Forms from the cooling of magma inside Earth | Intrusive Igneous Rocks |
Least dense layer of Earth, coolest in temperature | Crust |
Layer that is denser than the crust, hotter than the crust, has convection currents | Mantle |
Layer that is denser than the crust and mantle, is liquid | Outer Core |
Layer that is the hottest and most dense layer of Earth, solid | Inner Core |
Best mixture for growing crops - sand, silt and clay | Loam |
Occurs when rocks and soil move suddenly | Mass Wasting |
Physical breakdown of rock by tree roots, ice wedging, abrasion, etc. | Mechanical Weathering |
Forms as existing rocks are subjected to heat and pressure | Metamorphic rocks |
Least reliable clue to a mineral's identity | Mineral Color |
Uses 1-10 to determine hardness. 10 is the hardest. | Moh's Scale |
The ability of air and water to pass through soil particles. | Permeability |
Earthquakes, volcanoes, mountains, valleys, ocean ridges, trenchs, islands | Landforms/Results of Plate Movement |
Luster, hardness, color, radioactivity, fluorescence, streak, cleavage, fracture, scratch, etc. | Properties of Minerals |
Forms from pieces of rock (sediments) that are compacted and cemented | Sedimentary Rocks |
Weathered rock and decayed organic material | Soil composition |
the layers of a soil profile | Horizons |
O, A, B, C, D/R | Soil Profile Horizons - top to bottom |
organic material - dead decaying plant and animal remains | Humus |
sand - largest, silt - smaller, clay - smallest | Soil Particle Size |
plates scrape/grind past each other, forms fault zone | Transform Boundary |
Breaking down of rock | Weathering |
