Question

sometimes, one plate moves under another plate at a convergent boundary. what is this process called? image of plate tectonics sea floor spreading convection currents subduction weathering most volcanoes occur near oceans deserts plate boundaries mountain ranges

Explanation:

First Question (Process at Convergent Boundary)

• Sea floor spreading: Involves new oceanic crust formation at mid - ocean ridges, not plate subduction at convergent boundaries.
• Convection currents: These are the driving force for plate movement in the mantle, not the process of one plate moving under another.
• Subduction: By definition, it is the process where one tectonic plate moves under another at a convergent boundary.
• Weathering: It is the breakdown of rocks at or near the Earth's surface, unrelated to plate movement at convergent boundaries.

• Oceans: While there are underwater volcanoes, most volcanoes are associated with plate boundaries rather than just oceans in general.
• Deserts: Volcanic activity is not a typical feature of desert regions as deserts are defined by aridity, not tectonic activity.
• Plate boundaries: At plate boundaries (convergent, divergent, transform), the movement and interaction of plates create conditions (like subduction, rifting) that lead to magma formation and volcanic eruptions. Most volcanoes are found near plate boundaries.
• Mountain ranges: Mountain ranges can be formed by plate boundaries, but the key location for most volcanoes is plate boundaries, not just mountain ranges.

Answer:

C. subduction
