Question

If Magma is thick, gas bubbles cannot escape and pressure builds up as the magma rises which can cause an eruption true or false

Answer 1

Answer:

             

            It is true. If Magma is thick, gas bubbles cannot escape and pressure builds up as the magma rises which can cause an eruption. With the accumulation and rise of bubbles through the magma chamber, the pressure increases and will eventually become great enough to break through overlying roof rocks, creating a conduit to the surface. The erupting gases force the magma out with great force, which breaks the lava into fragments that quickly cool and harden into pieces of different sizes.
