Is volcanism found at convergent and divergent boundaries of tectonic plates?
Yes, volcanism is found at both convergent and divergent boundaries of tectonic plates. At convergent boundaries, subduction zones can result in the formation of volcanoes due to the melting of subducted crust. At divergent boundaries, magma rises to the surface to create new crust, leading to volcanic activity as seen in mid-ocean ridges.
At which type of plate boundary does rift-volcanism occur?
Rift volcanism occurs at divergent plate boundaries, where tectonic plates move away from each other, causing magma to rise to the surface and create new crust as it cools and solidifies. This process is often associated with the formation of mid-ocean ridges and rift valleys.
What geological processes cause volcanism?
Volcanism is caused by the movement of tectonic plates, which can create magma chambers beneath the Earth's crust. This magma can rise to the surface through fissures or vents, causing volcanic eruptions. Subduction zones, hot spots, and divergent boundaries are common geological settings where volcanism occurs.
What boundary are trenches found?
Trenches are found in a divergent boundary.
Where are divergent boundarys found?
Divergent boundaries are found primarily along mid-ocean ridges, where tectonic plates are moving away from each other. Additionally, divergent boundaries can also occur on continents, leading to the formation of rift valleys.

What types of volcanic rocks are generally found at divergent plate boundaries?
Basaltic rocks are generally found at divergent plate boundaries. These rocks form from the solidification of lava that erupts from mid-ocean ridges and oceanic rift zones, which are common features at divergent plate boundaries. Basaltic rocks have a low silica content and are dark in color.

Where can divergent divergent boundary be found?
Most divergent boundaries can be found on the ocean floor. divergent boundaries create Rift Valleys An example of this is the Mid-Atlantic Ridge discovered by Harry Hess.
Characterized by basaltic volcanism and seafloor spreading?
This description is often associated with mid-ocean ridges where new oceanic crust is formed through seafloor spreading, creating basaltic volcanism. These ridges are areas of tectonic activity where magma rises to the surface, solidifying into basaltic rocks.
What boundary are trenches found?
Trenches are found in a divergent boundary.

Which type of rock is associated with volcanoes?
Igneous rocks are found in areas of volcanism
Were are pumice rocks found?
In areas of past or present explosive felsic volcanism
What is found at the mid-ocean ridges?
New oceanic crust from rift volcanism.
