what create lava domes, plateaus and volcanoes?
Answer (1)
Lava domes, plateaus, and volcanoes are formed by different volcanic processes related to the movement and eruption of magma from beneath the Earth's surface.1. Lava Domes – Formed by slow, viscous lava (usually andesite or rhyolite) that piles up near the vent instead of flowing far. Since the lava is thick, it cools and hardens quickly, creating steep-sided domes.2. Lava Plateaus – Formed by large-scale fissure eruptions that release highly fluid basaltic lava, which spreads out over vast areas before cooling. Over time, multiple layers of lava accumulate, forming a plateau. Example: Columbia River Plateau (USA).3. Volcanoes – Formed by magma rising through the Earth's crust and erupting as lava, ash, and gases. The type of volcano (shield, stratovolcano, or cinder cone) depends on magma composition, eruption style, and tectonic activity.These landforms are primarily shaped by tectonic plate movements—such as subduction zones, rift valleys, and hotspots—that generate and move magma.
