What happens at divergent and convergent plate boundaries?
Crust and mantle melt into magma
Earthquakes shake magma loose
Magma champers collapse into caldera
Sediment deposits become volcanic ash
Volcanic ash is produced during
explosive eruptions
lava flows
liquefaction
subduction
What is magma
Magnetic force under the ground
Type of tectonic plates
Hot, molten rocks
Lava
What is geyser
Lava flows
Magma chamber
Caldera in the center of volcano
Jet of stream of hot and steamed water formed at hot spots
The factor that helps magma to form in mantle at convergent boundary is
Shear force
Water carried from sink oceanic plate
Low pressure surface in the rift
The type of volcanoes that has violent and explosive eruptions is
Shield volcano
Caldera
Composite volcano
Primary Waves
Composite volcano has viscous (sticky) lava, because
magma will mix with part of continental crust while it erupts.
magma become cold while it erupts.
magma flow onto Earth's surface smoothly
As lava flow through the rift, cools and solidifies this will form
island
mid-ocean ridge
hot spring
Volcanic eruptions can block the sunlight
True
False
Mouna Loa volcano formed at
Divergent boundary
Convergent boundary
Transform boundary
