Geography Part A Plate tectonics is a theory that states that the Earth is divided into several plates that tend to float over the inner layer of the earth called mantle. Note that the earth crust/outer shell is much rigid compared to the mantle which is often fluid due changes occur over a long period that is decades. Throughout this duration several factors which acts like warnings might be noted. However when it comes to abrupt climate changes there are no warnings and thus the effects are usually catastrophic as people would not be able to adjust effectively. [...]
In your own words, using college level writing, describe plate tectonics to someone who has a high school education, but has never studied the process. You should include a few basic definitions and descriptions, and discuss the following: Part A What are plate tectonics? Why and how do plate tectonics occur? What are some potential hazards caused by plate tectonics? Part B What is abrupt climate change? How and why could abrupt climate change occur? How do we know abrupt climate change has occurred in the past?
