The Magna Carta, signed in 1215 by King John, was an important step in because it took some power from the monarch and gave it to the people. An example of this would be that the monarch could no longer take someone's land without just reason and payment to the person for the land. Because of this major step from traditional government, the Magna Carta is often regarded as the basis of Democracy. Never before had power been taken from the monarch and given to the people. It was, however, still a far cry from the consitutional monarchy that Great Britain has today.
A dike is an intrusive body of volcanic magma that pushes it's way between layers of rocks and sediment.
It depends on what you mean by "how old". Much of Tasmania is composed of dolerite which means the island began life as stewing magma agitating under the earth's crust until, some 145-199 million years ago, it spewed forth from the belly of the earth during the Jurassic period. Much later, about ten thousand years ago, Tasmania split off from the mainland of Australia, compelled by tectonic forces to begin a new life as an island. Anthropological evidence suggests man occupied Tasmania some 35,000 years ago, long before it drifted out to sea. In 1642, Abel Tasman, the European to discover the island, spotted Tasmania. British colonies occupied the island in the early 19th century.
Magma carta
The Magna Carta is a medieval charter that was signed by King John of England in 1215. It is Latin for "Great Charter" and it established principles such as the rule of law, limits on the power of the monarchy, and protection of individual rights. It is considered a cornerstone of constitutional law.
the rights of all free citizens to own and inherit property and to be protected from excessive taxes.
Silica is something in the magma, so it is a pretty important part of magma because it pretty much a part that makes magma!

The magma vent and crater are important parts of a volcano because they are pathways for magma to reach the surface. The magma vent allows magma to flow up to the crater, where it can accumulate and eventually erupt as lava and volcanic gases. Monitoring these areas can provide valuable information for predicting volcanic activity and protecting surrounding areas.
Pressure and magma
creater,vent and the magma chamber
magma chambers. These reservoirs can hold large volumes of magma and are important in the formation of volcanic eruptions.
An acid magma or a granitic magma.
The amount of silica in magma determines its viscosity or flowability. Magma with high silica content is more viscous and tends to trap gases, leading to explosive eruptions. Low-silica magma has lower viscosity and allows gas to escape more easily, resulting in less explosive eruptions.
The most common dissolved gas in magma is water vapor, or H2O. Other important gases that may be present in magma and released during volcanic eruptions are carbon dioxide, sulfur dioxide, and hydrogen sulfide.
