1. How have scientists gain knowledge of Earth's interior since no one has ever sampled the interior below the crust directly? Explain
2. What physical clues and evidence prove that the continental landmasses were together 225 million years ago as Pangaea and why do scientists think the continents are drifting?
3. If you were a petroleum geologist searching for oil deposits (derived from ancient biomass) why would you want to know the positioning of these landmasses 225 million years ago?
4. Using a physical Geography textbook, such as Geosystemsor a map, name the three lithospheric plates that converge on Japan.
5. The seamount, Loihi, is not yet above sea level. It will eventually break through the surface of the Pacific Ocean to become the newest Hawaiian Island. The seamount is growing taller through summit eruptions at a rate of 2 metres per year. When in years approximately will the seamount break through the surface of the Pacific Ocean? (Showwork i.e. do not just give an answer: add the formulae used to get your answer).
6. How can volcanic eruptions become natural disasters? Be specific about the types of events that can significantly affect the environment as well as human population in the vicinity of an eruption.
7. What is the relationship between an epicentre and the focus of an earthquake? You are a radio announcer. An earthquake just happened and you have to announce this event to the public. How will you craft the announcement to capture both the focus and epicentre?
