Explosions from composite volcanoes occur as a result of gas buildup within them. Shield volcanoes also may erupt explosively if water accumulates inside their vents.
lava with a higher content of <em>silica</em><em> </em>has higher viscosity
The volcano can collapse and form a <em>caldera</em>
shield volcanoes can form when less <em>viscous</em> lava flows quickly away from a vent
During an oceanic plate convergence, the <em>denser</em> plate will sink
The west coast of the united state has features formed by <em>subduction</em>
During the <em>divergence </em>of two tectonic plates, magma wills the space between two tectonic plates
The only volcanic activity that is not formed at tectonic plate boundaries is <em>hot spots</em><em> </em>and volcanoes are linked severe weather events
The response to all these is earthquakes
9. An explosive eruption is a very violent type of volcanic eruption and can be caused when enough gas has dissolved under pressure in a viscous magma in a way that when the lava is expelled it froths into volcanic ash when pressure is low at its vent

Creation of walkable neighborhoods with mixed-use land and access to public transportation
Explanation:
The goal of smart-growth planning is to produce a pattern of compact and contiguous development to limit urban sprawl. Walkable neighborhoods with mixed-use land and access to public transportation are part of the design goals.
France may have been Britain's key ally, and the British government accepted that it had no choice but to stand by France for so long as the war was being fought.
