Question
Chapter 5, Problem 1RQ
To determine
The products of volcanic eruptions.
Expert Solution & Answer
Answer to Problem 1RQ
The thermal energy inside the earth is leads to volcanic eruption, and lava flows, pyroclastic debris, and gas are all the byproducts of magma.
Explanation of Solution
A volcanic eruption brings materials from inside the earth to surface of the earth.
The three different kinds of products of an eruption are lava flows, pyroclastic debris, and gas. Lava is molten rock, lava flows downward through the sides of the volcano like a condensed liquid, and lava gets cooled on the ground.
Pyroclastic debris is seen as ash, lapilli (plum sized material), blocks (fragments of pre-existing rocks), bomb (apple sized rock material). When the volcanic eruption happens, which sends volcanic gases into the atmosphere and the gases eruption are water vapor, carbon dioxide, sulfur dioxide, hydrogen sulfide, carbon monoxide.

Calculate the elevation of the water table at each well location and write the approximate elevation on the line next to each well. Next, use a colored pencil to draw smooth 10-foot contours that show the shape of the water table. (Start with the 1160-foot contour.) Use a pencil of a different color to draw arrows on the map to indicate the direction of the slope of the water table. a. Toward which direction (downward) does the water table slope? b. Referring to the site of the proposed water well, at approximately what depth below the surface should the proposed well intersect the water table? 2. Assume that a dye was put into well A on May 10, 2017, and detected in well B on May 25, 2018. What was the rate of groundwater movement between the two wells, in centimeters per day?
