EAST AFRICA’S GREAT RIFT VALLEY 2 INTRODUCTION This article.” East Africa’s Great Valley: A Complex Rift System” (EARS) written by James Wood and Alex Guth, tells their belief about how the East African Rift System came about. Wood and Guth describes a rift as being a fracture in the earth’s surface that widens over time, or more technically, as an elongate basin bounded by opposed steeply dipping normal faults. The article goes on to say that EARS are one of the geologic wonders of the world, and how the earth’s tectonic forces are presently trying to create new plates by splitting apart old ones. They stated that the purpose of this article is to discuss the,” general geology of the rifts and to highlight the geologic process involved in their formation.”(Wood and Guth, 2014) BRIEF OVERVIEW AND MAIN POINTS Within this article is the continuing saga of how the earth was created. Wood and Guth explains how the rifts are cracking and separating. The separating has gone on to form new plates that are so displayed in East Africa, that geologists have begun to name them. They also explain in great detail how the Nubian Plate and the Somalian Plate are not only moving from each other but also from the Arabian Plate to the North. They explain that all rifting in East Africa is not confined to the Horn of Africa but is further south as well. STRENGTHS OF THE ARTICLE One of the strengths of the article is how Wood and Guth explained with great detail what their beliefs were. They were knowledgeable about how rifts are formed and the cracking EAST AFRICA’S GREAT RIFT VALLEY 3 and separating process. When they explained the geological process it was done with great clarity which made it easy to understand. The addition of the area maps were a
