What are volcanoes?

A volcano is a crack in a planet's crust, such as the one on Earth, that permits hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.

Most volcanoes on Earth are found underwater, and they are most frequently found where tectonic plates are diverging or convergent.

For instance, the Pacific Ring of Fire has volcanoes created by convergent tectonic plates while the Mid-Atlantic Ridge has volcanoes caused by divergent tectonic plates.

When ash and sulfuric acid droplets block the Sun and cool the Earth's troposphere, large eruptions can change the temperature of the atmosphere.

Large volcanic eruptions have historically been followed by volcanic winters that resulted in terrible famines.

Answers

A logical hypothesis, if a detailed map is discovered about a location, is that the map's creator must have been to that location. This relates to Archeology.

What is an example from the unit that illustrates how an archaeological find can redefine or rewrite history?

One of the archeological findings that changed history is the discovery of Tutankhamun's tomb.

This discovery enhanced the knowledge of what an Egyptian King's tomb looked like and expanded the world's knowledge about Egypt.

How did the destruction of the Library of Alexandria affect history?

It is important to state that although Alexandria's library held very important information that would have served mankind, its absence was not really missed because other great libraries existed at that time such as the Library of the Roman Empire.

What do Defixiones tell us about human nature?

Defixiones are sheets of lead or pewter inscribed with curses. They tell humanity that it is commonplace for human beings to hold grudges.

And to satisfy these grudges, they sometimes wish for higher powers to exact vengeance on those that have hurt them.

In divergent boundaries hot material rises, separating tectonic plates and creating new crust between them. D) Ocean basins grow wider as new oceanic crust forms at a divergent boundary.​

What is the divergent boundary?

In Divergent boundaries, new crust is created by the molten materials rising from the mantle.

Two plates separate, and the stream of hot material creates a new seabed between them. It occurs as an expansion of the sea bottom.

As old plates get separated, the new and young crust instantaneously gets formed. The emerging mantle occupies the space left by the separation of the two plates.

This process occurs along with an underwater mountain range, known as the mid-oceanic ridge or divergent ridge.

The seafloor spreading is the process through which these tectonic plates separate from each other as a consequence of the rising mantle.

The correct option is D. Ocean basins grow wider as new oceanic crust forms at a divergent boundary.​
