Quiz 3

Which of the following sites would most likely have composite volcanoes? A is on an island arc, B is in the Andes, C is near Hawaii, D is along a mid-ocean ridge.

A and B

What type of volcanic eruption is shown in this photograph?

a pyroclastic column

What type of weathering is best expressed in this weathered limestone?

dissolution

Long, thin lava flows are typically produced by:

low-viscosity lavas

Which of the following is NOT a typical match between the type of eruption and resulting rock type?

pyroclastic flow - scoria

This volcano is broad and low, and is composed of basaltic lava flows. What kind of volcano is it?

shield volcano

Which of the following environments would most likely have sediment formed by evaporation of seawater?

tidal flat at E

Magma rising through the crust fractures rocks, producing rhythmic, repeating:

Seismic shaking

What happens to the majority of sediment being carried by moving water as it enters a standing body (little or no motion) of water?

The sediment gradually settles to the bottom.

Downslope marine flows comprised of mixed masses of sand, and water are called:

Turbidity currents

Changes in topography, water chemistry, and gas output all are used to help predict:

Volcanic eruptions

If a rock is poorly sorted, this means the rock contains:

a wide range in the size of clasts

Shallow coastal accumulations of sand that rise above the sea as long, narrow islands are called:

barrier islands

If bubbles cannot escape easily from a magma, the resulting eruption is likely to:

be explosive

This relatively large, symmetrical volcano contains interlayered lava flow, pyroclastic deposits, and volcanic mudflows. What kind of volcano is it?

composite volcano

What type of volcano is Mount Rainier?

composite volcano

Which of the following is NOT involved in turning some sediment into sedimentary rock?

metamorphism

Rocks rich in what mineral tend to have a poor solubility during weathering?

quartz

Fluvial refers to:

the processes and sediment of streams and rivers

This relatively small volcanic feature consists of solidified lava and some volcanic ash. What kind of volcano is it?

volcanic dome
