Question:

Despite the common knowledge, most rocks are hard, what evidence is there to show that they can also be soft?

Luke S.
Answer:

Certain outcrops, cliffs or mountain ranges show a process named folding which is proof of the malleability of these materials. Folding is a slow acting process often taken several thousands of years, where layers of rock can be bent and squashed similarly to bread slices. If the process occurs too quickly the typically behave brittlely and break of form jagged edges (e.g. mountain ranges).

Question:

What is the difference between global warming and climate change? And how is carbon sequestration important in maintaining a stable climate?

Luke S.
Answer:

The difference between climate change and global warming is found in the contrasting frequency and the difference in what constitutes their dynamic processes. Climate change is a change in the long term status of the climate of a region. Where the weather is the daily and/or weekly conditions of a region, climate takes into account the sum of all of these frequently daily weather changes and exhibits the overall averages in the format of the climate. Global warming is also an event the is re-occurring however is the title for a process typically created by the environment. Before the industrial age, global warming was a natural accumulation of various greenhouse gases (e.g. CO2, MH4) that altered the atmospheric composition of Earth resulting in increased absorption of ultraviolet radiation. This increase heated the planet's average global temperature creating a global warming effect. This process is now enhanced by the addition of greenhouse gases produced by anthropogenic activities. Carbon sequestration helps to combat this effect by storing the aforementioned greenhouse gases in various sources. Many examples of this relate to the process carried out by plants, photosynthesis. The process consumes carbon, among other elements and stores them into the plant material. Oceans and seagrasses also aid with carbon sequestration. Unfortunately, there is still an excess of greenhouse gases, and deforestation prevents the current processes to cope with the amounts in the atmosphere.

Question:

Describe the key aspects that a required to form what we know as a society and extrapolate on how these have evolved over time to the detailed compartmentalisation of society that we know today?

Luke S.
Answer:

Society as a whole is no one single entity but a multitude of components that when put together bring it into existence - a form of 'emergence'. It is a concept that is fluid and although the following like aspects a typically required to create a society - note that all of them can be altered at any time while still maintaining this entity. Society requires a population, a purpose in life and an ability to create a sense of security and stability. These 3 factors may change in that populations can be lost to war or disease, a purpose in life is very subjective and could range from occupational to spiritual depending on the individual and a sense of safety is created by the population and the environment in which they live/have created. This has evolved from the first band of wandering nomads to present day in an array of ways. Governments, geopolitical borders, and pursuits, global communication and monitoring, immigration and transportation, to name a few. Each of these builds upon those three initial aspects and continue to add and improve on there based on the needs and desires of the society that developed them.
