PATTERNS OF PARAGRAPH DEVELOPMENT
Definition
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.
Exemplification
Earth's volcanoes occur because its crust is broken into 17 major, rigid tectonic plates that float on a hotter, softer layer in its mantle.[1] Therefore, on Earth, volcanoes are generally found where tectonic plates are diverging or converging. For example, a mid-oceanic ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates pulling apart; the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates coming together. Volcanoes can also form where there is stretching and thinning of the crust's interior plates[clarify], e.g., in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande Rift in North America.
Persuasion
Most people have a natural fear of death- its a trait man have to think about what will happen before we act. If we don’t think about it consciously, we will think about it unconsciously. Think- if every murderer who killed someone died instantly, the homicide rate would be very low because no one likes to die. We cannot do this, but if the Justice system can make it more swift and severe, we could change the laws to make capital punishment faster and make appeals a shorter process. The death penalty is important because it could save the lives of thousands of potential victims who are at stake (Bedau, H., 1982).
Chronology
A volcano begins as melted rock (magma) which rises from deep inside the earth toward the surface. As the gas-filled magma rises, it melts gaps in the surrounding rock and forms a large chamber. Pressure from the solid rock around it forces the magma up to the surface through the conduit (channel) in a weakened part of the rock. The gas and melted rock blast out an opening called the central vent.
Listing
If a volcano erupts in your area, evacuate only as recommended by authorities to stay clear of lava, mud flows, and flying rocks and debris. Avoid river areas and low-lying regions. Before you leave the house, change into long-sleeved shirts and long pants and use goggles or eyeglasses, not contacts. Wear an emergency mask or hold a damp cloth over your face. If you are not evacuating, close windows and doors and block chimneys and other vents, to prevent ash from coming into the house. Be aware that ash may put excess weight on your roof and need to be swept away. Wear protection during cleanup.
