What sort of a plate is the Sunda plate?
Geology & LandformAsked by: Jim Greenwood The Sunda Plate is a minor tectonic plate straddling the Equator in the Eastern Hemisphere on which the majority of Southeast Asia is located. The Sunda Plate was formerly considered a part of the Eurasian Plate, but the GPS measurements have confirmed its independent movement at 10 mm/yr eastward relative to

What causes volcanoes to erupt?
Geology & LandformAsked by: Sabrina Stepanova The melted rock, or magma, is lighter than the surrounding rock and rises up. This magma collects in magma chambers, but it is still miles below the surface. When enough magma builds up in the magma chamber, it forces its way up to the surface and erupts, often causing volcanic eruptions.

What are the two main geological processes?
Geology & LandformAsked by: Michelle Garcia Geologic Processes Weathering – responsible for landslides, subsidence. Erosion – responsible for landslides, subsidence, flooding. What are the major geological processes? The four major geological processes are impact cratering, volcanism, tectonics, and erosion. Earth has experienced many impacts, but most craters have been erased by other processes. We owe the existence

Where was Big Sur landslide?
Geology & LandformA 150-foot-stretch of the roadway, located about 15 miles south of the town of Big Sur, completely fell away on Jan. 28 during a mudslide caused by a burn scar. This is far from first time that a landslide has forced the closure of a section of Highway 1 in the Big Sur area, which

Can seafloor spreading cause earthquakes?
Geology & LandformVolcanic activity causes the seafloor to spread along oceanic ridges, forming new areas of crust and mantle. After being generated, this new oceanic lithosphere cools down and contracts by up to 3% of its own volume. This contraction can trigger oceanic earthquakes. How does seafloor spreading related to volcanoes? Volcanic activity causes the seafloor to
