May 8, 2023 · Ocean trenches and rift valleys are two of the most prominent and fascinating geological features of the Earth’s crust. These are long, narrow depressions that are formed due to tectonic plate movements. Ocean trenches are deep, elongated depressions on the ocean floor, while rift valleys are narrow, elongated depressions on land or under the ...
Apr 3, 2018 · This photo shows a large crack that recently appeared in the East African Rift Valley. The crack, which is up to 50 feet deep and 65 feet wide significantly damaged a major road and destroyed homes. The East African Rift Valley is one of the most famous geologic regions on earth. Stretching for over 3,000 km from the Gulf of Aden in the north ...
Mar 20, 2024 · 13. Lake Kyoga, Uganda. Located in Northern Uganda, this large, shallow lake is part of the Great Rift Valley but is not considered to be a great lake. Lake Kyoga is fed by the Victoria Nile. Water flows in from Lake Victoria and then flows out to Lake Albert. Lake Kyoga is reaches a maximum depth of just 5.7 meters.
The geologic term for this type of tectonic depression is “ graben ,” the German word for “ditch” or “trough.”. Tectonic depressions also can be produced by horizontal compression of the crust— i.e., by crustal shortening. Two types of compressional tectonic valleys and basins can be recognized: ramp valleys and foreland basins.
Here is an animation from the United States Geologic Survey (USGS) of divergent plate boundary at mid-ocean ridge and another animation by IRIS.As divergence occurs, shallow earthquakes can occur along with volcanoes along the rift areas. When the process begins, a valley will develop such as the Great Rift Valley in Africa.
The East African Rift, also called the Great Rift Valley in East Africa, is the largest continental rift valley on Earth, stretching for about 3000 miles north and south and reaching up to 37 miles wide. The deepest portion is 6,000 feet below the surrounding area. As the tectonic plates on each side continue to move apart, during the next 10 ...
Mar 27, 2024 · The most famous rift on Earth is the Great Rift Valley, which stretches from the Middle East in the north to Mozambique in the south. What was the Great Rift nicknamed? The Great Rift is sometimes called the Dark Rift or the Dark River in astronomy due to interstellar clouds of cosmic dust that obscure the view of the Milky Way galaxy.
