An explosive volcanic eruption does not produce lava flows because Choose one: A. the lava produced cools too quickly due to the

abundant water in the surrounding environment. B. the sudden release of accumulated gas pressure blasts the lava upward, forming pyroclastic debris. C. the gases below the surface rise and cause the magma to cool and solidify. D. the overriding plate at the subduction zone where the volcano formed is composed of oceanic lithosphere.

Answer:

B. the sudden release of accumulated gas pressure blasts the lava upward, forming pyroclastic debris.

Explanation:

Lava flows occurs in non explosive eruptions. This is because it is favored by low gas and low viscosity which brings fire fountain when the gases dissolves. For explosive eruptions, the pressure blast the lava upwards forming debris instead. So when this happens, it sends ash, gas and magma high up into the atmosphere. These eruptions occurs when sufficient gas has dissolved under pressure within a viscous magma in such a way that the lava is expelled violently froths into volcanic ash when pressure is suddenly lowered at the vent.

Which statement best compares the movement of P waves and S waves?
ikadub [295]

Answer:

C.  P waves move matter back and forth, in a direction parallel to the direction of the wave, while S waves move matter up and down, perpendicular to the direction of the wave.

Explanation:

P and S - waves are both called seismic waves. They are produced during deformation within the earth.

Usually, P or Primary waves have the fastest velocity and arrives at the seismic station first. Secondary, Shear or S-waves follows P-waves.

  • P-waves are body waves that propagates within a body. They cause movement internally.
  • Secondary waves are surface waves. They move on the surface of earth.
  • One way to also distinguish between these two seismic waves is that, P-waves are longitudinal waves that travels parallel or longitudinally to the source.
  • Secondary waves moves in an up and down motion pattern. They propagate transversely to their source.

Because there is more friction, heat, and weight the further you go down.
