Which mountain type is described as the lighthouse of mediterranean?

Analyze the question: The question asks which mountain type is called the "lighthouse of the Mediterranean." This refers to a famous mountain with a nickname linked to its activity.

Explain the concept: Stromboli is a volcano on an island off the coast of Sicily, Italy, in the Mediterranean Sea. It has erupted almost continuously for thousands of years, throwing out glowing lava and ash at regular intervals. At night the glow is visible from far away, and sailors used it as a natural navigation beacon. That is why it is nicknamed the "Lighthouse of the Mediterranean."

Solution:

1. The "lighthouse" nickname comes from a light, a glow of fire, that can be seen from far away.
2. Only an erupting mountain produces such a glow, so it must be a volcano.
3. Check the options: • A. Block mountains are formed by faulting (uplifted crustal blocks). They do not glow. • B. "Flow" is not a recognised mountain type. • C. Residual mountains are remnants left by erosion. They do not erupt. • D. Volcanic mountains are built from lava and ash. Stromboli is one, and it fits.

Answer: D. volcanic

Tip: When you see a nickname that involves fire, light, or smoke, think volcanic. Remember: Stromboli = Strong glow = Volcano. Also review other famous volcanoes, such as Vesuvius, Etna, and Mount Cameroon, which is West Africa's well-known example.
