| Question | Answer |
|---|---|
| Physical disintegration of rocks into smaller pieces is called | mechanical weathering |
| The decomposition of rock from exposure to water and atmospheric gases is known as: | chemical weathering |
| A mechanical weathering process caused by pressure release (or unloading) is | exfoliation |
| Where do sediments come from? | Rock weathering produces sediment. |
| In which environment is frost wedging likely to be prevalent? | a high mountain |
| Silt is a product of: | mechanical weathering |
| Hydrolysis occurs when | feldspars are chemically altered to clays |
| Exfoliation is a natural process which results from | unloading of deeply buried rocks |
| The common end product of the chemical weathering of feldspar is: | clay. |
| Soil with approximately equal proportions of sand, silt, and clay along with generous amounts of organic matter is called | loam |
| Which soil forms in arid climates, with little organic material? It usually includes hardpans of salt, gypsum or calcite | Aridisols |
| The soil horizon rich in clay is the: | B horizon |
| Tropical soils are typically | deeply leached and infertile |
| The single most effective agent of chemical weathering at the Earth's surface is | carbonic acid |
| When feldspar weathers, it turns to | clay |
| Which of the following minerals would weather away the fastest at the Earth's surface | olivine |
| Where do aluminum cans come from | laterite soil |
| What is the parent material of all soils?` | rock |
| A sedimentary rock can be | produced from weathered products of pre-existing rocks |
| Where do sediments come from? | Rock weathering produces sediment |
| Based on your experience, which of these environments will produce sediments with cross-bedding? | cross-bedding may develop in all these environments |
| Particles of sediment from 4 mm to 2 mm diameter are called | gravel. |
| Rounding is | the grinding away of sharp edges and corners of rock fragments during transportation |
| Compaction and cementation are two common processes associated with | lithification |
| Which of the following is a chemical sedimentary rock | limestone, rock salt, rock gypsum |
| The major difference between sandstone and conglomerate is | grain size |
| Which of the following is a type of sandstone | breccia,conglomerate, arkose |
| Shale differs from siltstone in that | shale has smaller grains than siltstone |
| The chemical element found in dolomite that is not found in limestone is | magnesium |
| A body of sedimentary rock of considerable thickness and with features that distinguish it from adjacent rocks is | a formation |
| If sea level rises or the land sinks, what is likely to occur? | a transgression |
| The process whereby rocks are changed to sediment is called | weathering |
| A sedimentary rock composed of rounded particles of gravel is called | clay |
| A layer in which the grain size becomes smaller vertically within the layer is called | graded bedding |
| Cross-bedding observed in sand dunes can be used | to determine the direction the wind was blowing |
| Sedimentary rocks provide clues about | depositional environments, The plate tectonic setting when the sediment was deposited, where the sediments originally came from |
| Foliation is | the alignment of minerals or grains due to differential stress |
| Foliated metamorphic rocks commonly contain | mica |
| Shearing is a response to: | differential stress |
| Metamorphic rocks in which minerals are NOT aligned within the rock are | non-foliated |
| Metamorphic rocks are classified primarily according to | whether they are foliated or non-foliated |
| The major difference between metamorphism and metasomatism is | metasomatism is metamorphism with the introduction of additional ions from an external sour |
| Ore bodies at divergent plate margins are commonly formed by | hydrothermal processes |
| Metamorphic minerals that form under a limited range of temperature and pressure are called | index minerals |
| A metamorphic rock that has undergone partial melting to produce a hybrid metamorphic-igneous rock is called | migmatite. |
| Which of the following lists is arranged in order from lowest to highest grade of metamorphic rock | slate, phyllite, schist, gneiss |
| Regional metamorphism is associated with | convergent plate boundaries |
| The generally accepted temperature limits for metamorphism are | metamorphism is limited by pressure, not temperature |
| The principal agents of metamorphism are: | temperature, pressure and fluids |
| When rocks are metamorphosed, the mineral components of the rock are | changed in the solid state |
| Contact metamorphism results whenever | a body of magma comes in contact with solid rock |
| Gneiss is a metamorphic rock type associated with | high pressure, high temperature conditions |
| Shale is a metamorphic rock associated with | Shale is not a metamorphic rock |
