Earth Science 13
Describe how plants promote mechanical and chemical weathering but inhibit erosion.

Earth Science 13
Dust collecting on furniture is an everyday example of a sedimentary process. Provide another example of a sedimentary process that might be observed in or around where you live.

Earth Science 13
Each statement describes how an intrusive feature appears when exposed at Earths surface by erosion. Name the feature. a. A dome-shaped mountainous structure flanked by upturned layers of sedimentary rocks. b. A vertical wall-like feature a few meters wide and hundreds of meters long. c. A huge expan

Earth Science 13
During a field trip with your geology class you visit an exposure of rock layers similar to the one sketched here. A fellow student suggests that the layer of basalt is a sill. You, however, disagree. Why do you think the other student is incorrect? What is a more likely explanation for the basalt la

Earth Science 13
. Referring to the accompanying hypothetical plate map, complete the following: a. Portions of how many plates are shown? b. Is continent C moving toward or away from continents A and B? How did you determine your answer? c. Explain why active volcanoes are found on continent A and continent B. d. Wh

Earth Science 13
Suppose a sliver of oceanic crust was discovered in the interior of a continent. Would this support or refute the theory of plate tectonics? Explain.

Earth Science 13
Granite and basalt are exposed at Earths surface in a hot, wet region. Will mechanical weathering or chemical weathering predominate? Which rock will weather more rapidly? Why?

Earth Science 13
Briefly describe the concept of elastic rebound. Develop an analogy other than a rubber band to illustrate this concept.

Earth Science 13
Describe an environment within Earth where you might expect rocks to experience ductile deformation. Suggest a scenario in which brittle rather than ductile deformation might occur

Earth Science 13
For each of the accompanying four sketches, identify the geologic setting (zone of volcanism). Which of these settings will most likely generate explosive eruptions? Which will produce outpouring of fluid basaltic lavas?

Earth Science 13
Examine the accompanying photos, which show the geology of the Grand Canyon. Notice that most of the canyon consists of layers of sedimentary rocks, but if you were to hike down into the inner gorge you would encounter the Vishnu schist, a metamorphic rock. a. What process might have been responsible

Earth Science 13
. Examine the accompanying photo and complete the following: a. What type of volcano is it? What features helped you make a decision? b. What is the eruptive style of such volcanoes? Describe the likely composition and viscosity of the magma. c. Which one of the three zones of volcanism is the likely

Earth Science 13
The accompanying photo shows a footprint on the Moon left by an Apollo astronaut in material popularly called lunar soil. Does this material satisfy the definition we use for soil on Earth? Explain why or why not. You may want to refer to Figure 4.12.

Earth Science 13
Match each of these volcanic regions with one of the three zones of volcanism (convergent plate boundaries, divergent plate boundaries, or intraplate volcanism): a. Crater Lake b. Hawaiis Kilauea c. Mount St. Helens d. East African Rift e. Yellowstone f. Vesuvius g. Deccan Plateau h. Mount Etna

The dimensions of the cumulonimbus cloud pictured in Figure 17.21H are roughly 12 km tall, 8 km wide, and 8 km long. Assume that the droplets in every cubic meter of the cloud total 0.5 cubic centimeter. How much liquid does the cloud contain? How many gallons is this (3785 cm3 = 1 gallon)?

Earth Science 13
If the budget of a valley glacier were balanced for an extended span of time, what feature would you expect to find at the terminus of the glacier? Now assume the glaciers budget changes so that wastage exceeds accumulation. How would the terminus of the glacier change? Describe the deposit you would

Earth Science 13
Refer to the accompanying diagrams to answer the following: a. What type of dip-slip fault is shown in Diagram 1? Were the dominant forces during faulting tensional, compressional, or shear? b. What type of dip-slip fault is shown in Diagram 2? Were the dominant forces during faulting tensional, comp

Earth Science 13
The circumference of Earth at the equator is 24,900 miles. Calculate how fast someone at the equator is rotating in miles per hour. If the rotational speed of Earth were to slow down, how might this impact daytime highs and nighttime lows?

Earth Science 13
Refer to Figure 3.2. How does the rock cycle diagram, in particular the labeled arrows, support the fact that sedimentary rocks are the most abundant rock type on Earths surface?

Earth Science 13
Compare the sediment deposited by a stream, the wind, and a glacier. Which deposit should have the most uniform grain size? Which one would exhibit the poorest sorting? Explain your choices.
