D. exhausting a natural resource is not sustainable
I'd have to say gas because it usually doesn't change at all
The Neolithic revolution was the first agricultural revolution. It was a gradual change from nomadic hunting and gathering communities and bands to agriculture and settlement. This period is described as a "revolution" because it changed the way of life of communities which made the change. It occurred in different prehistoric human societies at different times. Many societies changed 9–7 thousand years ago.
The term refers to the general time period over which these developments took place. It also applies to the changes which took place: the adoption of early farming techniques, crop cultivation, and the domestication of animals. The Neolithic Revolution is important for developments in social organization and technology.
The Neolithic revolution led to living in permanent or semi-permanent settlements. Because of this fewer people led a nomadic lifestyle. To be able to know who the crops grown belonged to, the concept of land ownership was developed. The natural environment was changed, population densities grew, and people ate more vegetable and cereal foods in their diet. Hierarchies developed in society. Grain was stored, and could be traded. Surplus production from good crop yields helped societies survive bad years.
The moon. Gravity between the Earth and the Moon causes water to bulge out.
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!
