Question 7 of 18

Based on history of the region containing Acadia National Park and the color of the rocks (from 3,000 ft), what type of igneous rock occurs in this area? (Hint- What color do the rocks in the outcrop below the parking lot appear? Zoom out to about 1,400 miles. What physiographic province is this according to Figure 14.1? According to the description of this province, what sort of rocks are these? Think about which rocks cooled slowly underground (phaneritic), and which cooled above ground from a magma (aphanitic). How did these rocks cool? were they intrusive, or extrusive in this province? Look up the names of the intrusive and extrusive igneous rocks as described in your e-textbook, sections 4.1.1 through 4.1.3. Select from the following choices which rocks the ones shown in the Google Earth satellite image, from 3,000 ft, that these could be. Granite and rhyolite are usually pink, gabbro is a very dark-colored mafic rock. Diorite and andesite are intermediate igneous rocks with equal light and dark mineral grains, and usually appear gray colored.)

  A. Gabbro

  B. Granite

  C. Rhyolite

  D. Basalt

  E. Diorite

Question 8 of 18

What type of igneous body does this structure represent? (Hint- see figure 9.6; a stock is a type of pluton. Review section 4.1.3 in the e-textbook for descriptions of igneous rock bodies. What general shape is the rock outcrop from 3,000 ft? Is it linear, flat, or rounded?)

  A. Stock

  B. Dike

Question 10 of 18

p. 343, Congaree National Park - What is the maturity of the river in this area? (Hint- see Chapter 5, compare with the descriptions and graphics on p. 96. Is there a well-developed flood plain?)

  B. Mature

  C. Old Age

Question 11 of 18

Zoom out to an eye altitude of 500 miles to see the source of the sediment that is accumulating in this area. This sediment is ____________ and if lithified would be called ____________ . (Hint- what province is this? Read the description of this province in section 4.2.2 in the lab manual. How long has this sediment been accumulating?
