Question

which of the following is an example of the effect on human life of the processes within the interior of the earth (the lithosphere)?

the mojo layer marks the division between the crust and the mantle.
hurricane katrina devastated the city of new orleans.
earths inner core is made of solid iron.
volcanoes frequently erupt around the ring of fire.

Explanation:

Analyze the question requirements

The question asks for an example of the effect on human life of internal Earth processes (lithospheric activity).

Evaluate the options

• Option 1 describes a geological boundary (Moho layer), which is a scientific fact but does not directly describe an effect on human life.
• Option 2 describes a hurricane, which is an atmospheric/meteorological process, not an internal Earth process.
• Option 3 describes the composition of the inner core, which is a geological fact but does not directly describe an effect on human life.
• Option 4 describes volcanic eruptions around the Ring of Fire. Volcanism is an internal Earth process (lithospheric activity) that directly impacts human settlements, safety, and agriculture.

Select the correct option

Option 4 is the only choice that connects an internal Earth process (volcanism) to an impact on human life/environments.

Answer:

• The Moho layer marks the division between the crust and the mantle.
• Hurricane Katrina devastated the city of New Orleans.
• Earth's inner core is made of solid iron.
• Volcanoes frequently erupt around the Ring of Fire. (Correct answer)
