Pyroxene biotite mica K-rich orthoclase feldspar Na-rich plagioclase feldspar Which one of the following statements concerning cinder cones is not true? they are small volcanoes with fairly steep sides they are built mostly or entirely during one eruptive cycle the cinders and other pyroclastic particles are tightly welded into consolidated rock the cinders most commonly are basaltic Rocks composed of calcilc (calcium carbonate in limestone and marble) are very susceptible to which form of chemical weathering? Dissolution frost wedging hydrolysis oxidation Which mineral gives the red and pink colours to some soils and sandstones? olivine (Mg2Si04) hematite (Fc203) calcite (CaC03) graphite (C) Talus slopes are closely related to which process of mechanical weathering? Oxidation residual leaching humus formation frost wedging Which of the following conditions produces the highest rates of chemical weathering? warm climates, dry conditions cool climates, wet conditions cool climates, dry' conditions warm climates, wet conditions does not matter How does a conglomerate differ from a sedimentary breccia? the breccia clasts are angular: the conglomerate clasts are rounded breccia has a compacted, clay-rich matrix: conglomerate has no matrix a breccia is w'ell stratified: a conglomerate is poorly stratified breccia clasts are the size of a baseball: conglomerate clasts are larger Which of the following is a common mineral in evaporate rock?

Quartz feldspars carbonates micas none of the above

Explanation / Answer

6) c. Still

Still is a relatively thin tabular concordant body intruded along bedding planes

7) Na-rich plagiocase felspar

Discontinuous series include olivine, pyroxene, amphibole, biotite mica

8) c.The cinders and other pyroclastic particles are tightly welded into consolidated rock

The cinders and other pyroclastic particles are consolidated into welded tuff.
