The category of rock that might be forming in the sea near a volcano due to weathering is sedimentary rock. As volcanic materials such as ash and lava are weathered and eroded by water, they can break down into smaller particles. These particles may then accumulate on the seafloor, compact, and cement over time, leading to the formation of sedimentary rock. Additionally, volcanic activity can contribute to the creation of new sediments that further enhance this process.
When a volcanic cone collapses it forms a caldera.
Factors such as the type of eruption (explosive or effusive), the composition of the magma, and the presence of glaciers or erosion can all contribute to changing the shape of a volcano. Expansive eruptions can lead to the collapse of the volcano's summit, while erosion can alter its overall profile over time.
A form of volcano that collapses in on itself is called a caldera. This occurs when a volcano erupts and empties its magma chamber, leading to a significant loss of structural support. As a result, the ground above the emptied chamber collapses, creating a large depression. Calderas can be quite vast and may eventually fill with water, forming lakes.
Yes. All the Aleutian volcanoes are the result of subduction.
It is a shield volcano, a result of the Great African Rift Valley. It is located on the southern arm of the African Rift Zone.
Weathering and erosion, tectonic plates movement and human intervention ( for example: farming, civilization)
Not really. Earthquakes can and do occur when a volcano is forming, but the volcano is not a result of an earthquake. Volcanoes are formed when magma (molten rock) within the earth's crust reaches the surface.
They are not actually all hexagonal. They formed that way from the result of a volcano and cracks forming to bring the various shapes that they are.
Soil horizons develop as a result of various soil-forming processes such as weathering, organic matter accumulation, leaching, and soil mixing. These processes lead to the distinct layers or horizons that make up a soil profile, each with unique characteristics and properties.
Sedimentary rocks are made of particles that result from weathering and erosion of pre-existing rocks. These particles, such as sand, silt, and clay, are carried by water, wind, or ice and accumulate in layers, eventually forming sedimentary rocks through compaction and cementation processes.
a normally result of a volcano is subducting continental crust.
An example of weathering in the Edwards Plateau could be the process of exfoliation, where outer layers of rock gradually peel away due to expansion and contraction caused by changes in temperature. This can result in large slabs of rock breaking off and forming distinctive domed landforms in the region.

Fine silica sand results from well weathered quartz.
