Answer:
Fusion
Explanation:
Supernova Definition:
The supernova occurs after fusion begins to pile up iron in the high-mass star's core. Because iron fusion cannot release energy, the core cannot hold off the crush of gravity for long. In the instant that gravity overcomes degeneracy pressure, the core collapses and the star explodes.
Fun Fact!
Approximately one supernova occurs every second. Supernova happens more often than you might think: One occurs somewhere in the universe every second!
In areas where the plates come together, sometimes volcanoes will form. Volcanoes can also form in the middle of a plate, where magma rises upward until it erupts on the seafloor, at what is called a “hot spot.” The Hawaiian Islands were formed by such a hot spot occurring in the middle of the Pacific Plate.
what is continental drift?
A continental drift is when earth moves geologic time relative to each other part of ocean bay

Answer:Roman Agriculture describes the farming practices of ancient Rome, an era that lasted 1000 years. From humble beginnings, the Roman Republic (509 BCE to 27 BCE) and empire (27 BCE to 476 CE) expanded to rule much of Europe, northern Africa, and the Middle East and thus comprised a large number of agricultural environments of which the Mediterranean climate of dry, hot summers and cool, rainy winters was the most common. Within the Mediterranean area, a triad of crops was most important: grains, olives, and grapes.
The great majority of the people ruled by Rome were engaged in agriculture. From a beginning of small, largely self-sufficient landowners, rural society became dominated by latifundium, large estates owned by the wealthy and utilizing mostly slave labor. The growth in the urban population, especially of the city of Rome, required the development of commercial markets and long-distance trade in agricultural products, especially grain, to supply the people in the cities with food.

Explanation:
Answer:By far the most abundant volcanic gas is water vapor, which is harmless. However, significant amounts of carbon dioxide, sulfur dioxide, hydrogen sulfide and hydrogen halides can also be emitted from volcanoes
