QuestionAnswer
Which of the following explains why, unlike the Earth, the Moon's surface is marked by ancient impact craters? Tectonic activity is nonexistent on the Moon, whereas on Earth, tectonic processes such as mountain building, volcanic eruptions, and earthquakes constantly change the Earth's surface and have erased most evidence of ancient impact craters over time.
Which of the following is an example of weathering processes? The breaking apart of a boulder due to the freeze-thaw actions of water
A geologist tests exposed igneous rock for calcite with hydrochloric acid. As the wind picks up, she hears a portion of the coast fall into the ocean with large boulders. Which event represents an erosional process? Coastal boulders falling into the ocean
Which of the following does NOT cause chemical weathering? Heat
Which weathering process or processes explain the spheroidal weathering of some igneous rocks? Mechanical weathering followed by mechanical and chemical weathering
Which of the following explains why quartz is one of the primary components of sand? Resistance to mechanical and chemical weathering
Which of the following is a common problem caused by chemical weathering at open air mining locations? The creation of a solution of dissolved metal and sulfuric acid
Which of the following explains the geologic processes behind the formation of acidic rain? Acid rain is formed from air pollution.
Salt cracking is an example of which weathering process? Chemical and Mechanical weathering
Which of the following is an example of abrasion? Glaciers dragging rock clasts, sand, and silt across bedrock
A farmer is trying to determine the best way to ensure continued crop harvests in his plot of land. After plowing the field, the farmer should do which of the following? Replenish nutrients and humus in the soil
The surface down, which soil horizons are represented in a profile with four distinct layers: the topmost is decaying leaf litter and humus, the second is a mix of humus, sand, silt, and clay, the third is largely clay, and the bottom is decaying bedrock? O, A, B, C
Which of the following processes create distinct soil horizons? The transformation of soil by physical, chemical, or biological processes and the translocation of sediment and ions downward over time
Which of the following does NOT control the characteristics of a forming soil? Available nutrients
A geologist is examining a soil profile comprised mainly of red clay with a concentration of insoluble iron oxides and aluminum oxides. Under what climatic conditions did this soil likely form? A climate with high temperatures and high rainfall
Which of the following is a soil type largely characterized by its parent material? Andisol
Which of the following is NOT one of the three major categories of rapid mass wasting? Creep
A contractor wants to build a house at the base of a mountain and points out a plot beyond hummocky topography. Closer to the mountain, trees are tilted slightly uphill. A geologist warns against building there due to which mass wasting feature? Slump
Which of the following does NOT affect the occurrence of mass wasting events? The presence of constructed buildings
Which of the following is not a component of soil classification? The proportion of organic litter
