Volcanologists, or scientists who study volcanoes, are most likely to study the cooling of lava. They are interested in understanding the behavior, properties, and processes associated with volcanic eruptions, including the cooling and solidification of lava after it is erupted from a volcano. By studying the cooling of lava, volcanologists can gain insights into various volcanic phenomena and hazards.
A vulcanologist is most likely to study the cooling of lava after a volcanic eruption
A volcanologist or a geologist specializing in volcanoes would be most likely to study the cooling of lava after a volcanic eruption. They would investigate the physical and chemical properties of the cooling lava to understand its behavior and how it solidifies over time.

Volcanic eruptions are most likely to produce fragmental sedimentary rocks due to the rapid cooling and subsequent deposition of ejected volcanic material, such as ash, lava fragments, and rocks. These materials can accumulate, compact, and cement together to form rocks like tuff or volcanic breccia.
An increase in volcanic activity emitting ash and sulfur compounds into the atmosphere is most likely to cause Earth to cool by blocking sunlight. This phenomenon can lead to a short-term cooling effect on the climate known as volcanic winter.
Powerful explosive volcanic eruptions can release large amounts of ash and sulfur dioxide into the atmosphere, which can block sunlight and lead to a short-term cooling effect for a few years. However, this cooling effect is temporary and not likely to last for millions of years. Long-term climatic cooling would be influenced by other factors such as greenhouse gas concentrations and solar activity.
You are likely familiar with the term "Global Warming." Well, volcanic gases are essentially the same as those that scientist who subscribe to the the Global Warming theories claim man is producing. CO2, Sulfur Dioxide, hydrogen sulfide, etc.
The rock you are describing is likely obsidian. Obsidian is a naturally occurring volcanic glass formed during rapid cooling of lava. It is usually black in color and has a smooth, glassy texture.
