Base your answer to the question on the map below of Iceland, a country located on the Mid- Atlantic Ridge. Four locations are
represented by the letters A through D.
Figure 5
The fine-grained texture of most of the igneous rock formed on the surface of Iceland is due to
1. rapid cooling of the molten rock
2. high density of the molten rock
3. numerous faults in the island’s bedrock
4. high pressure under the island
-------------14.
What is the best way to determine if a mineral sample is calcite or quartz?
1.
2.
3.
4.
Observe the color of the mineral.
Place the mineral near a magnet.
Place a drop of acid on the mineral.
Measure the mass of the mineral.

15.
Which is the best explanation for the cleavage of mica into thin layers?
1.
2.
3.
4.

2. cooling and crystallization of magma
3. evaporation of an ancient ocean
4. heat and pressure during metamorphism

Where is metamorphic rock frequently found?
Base your answer to the question on the map below. The
represents Mt. Hekla, a volcano in Iceland. The isolines
represent the thickness of ash, in centimeters, that settled on
Earth’s surface after a volcanic eruption of Mt. Hekla on March
29, 1947. Point X is a location on the surface of the ash.
1. on mountaintops that have horizontal layers containing
marine fossils
2. within large lava flows
3. as a thin surface layer covering huge areas of the
continents
4. along the interface between igneous intrusions and
sedimentary rocks
--------------
Figure 9
In addition to the ash, solid rock formed on Mt. Hekla from the
lava extruded during this eruption. This rock is most likely
1. light-colored metamorphic
3. fine-grained igneous
2. dark-colored metamorphic
4. coarse-grained igneous
