radius. Although the shape of Earth is not exactly spherical, it has an average radius of 3960 miles. Estimate the surface area of Earth. The surface area of a sphere is found by using the following formula: s = 4r2, where s represents surface area and r represents radius. To find the approximate surface area of the Earth, the equation would be set up as follows: S = 439602 = 197060797.4 This calculation shows that the approximate surface area of the Earth 197060797.4 square miles.

Critically Evaluate the factors influencing the Global Heat Budget (40 marks) The global heat budget, also known as the atmospheric heat budget, is the balance between the incoming insolation (solar radiation), and outgoing radiation from Earth. Due to absorption, reflection and scattering throughout the atmosphere, the Earth’s surface only receives 24% of the incoming insolation. Whilst the atmosphere has a net deficit of energy, the surface has a net gain, except for the polar regions. This difference

must admit that I too enjoy “sitting glued” to the TV as mum often laments. Since I watch TV whole day long, I don’t blame mum.

If you only had one more day to live, how would you spend it and who would you spend it with? These are the questions that 7 billion people are going to be faced with in a few weeks. This is called the ‘’Theory of 2012’’ or “The end of the world’’ According to this theory, December 21, 2012 is the ‘’last day of earth’’. No matter how many reasons are given to prove this theory, there are still many controversies and speculations. The 2012 apocalypse is false because of too many proofs to this theory

Can we save the earth? While reading The Creation: An Appeal to Save life on Earth by E.O Wilson a lot of ideas popped up in my head. I have to admit some were crazy ideas but reading this book sparked them all. If the course didn’t require me to read at least two books from professors Isenhour list I probably wouldn’t have read this book. I’m glad I did because this is an issue that I have heard a lot about but never gave it importance. All my ideas which I will explain later on all lead to a question

Geologic features. The martian geology is different than Earth in many ways when it comes to the soil and the plate tectonics. Red soil. Mars is called the red planet for a reason. The soil on Mars is rich in magnetic iron oxides which is rust. Scientists took a soil sample that mimics that of Mars and tested it to see if it would rust the way it looks like on Mars. The iron was unchanged after a year in a dry atmosphere and finally changed when the sample was put in a wet atmosphere. (R., 2005)
