Complete the flow chart showing the arrangement of the following events leading to
a volcanic eruption. Write them on the boxes provided.
•Heated magma goes up.
•Enhanced formation of bubbles.
•Magma is ejected out as lava.
Magma is continuously heated below the earth's surface
•As magma rises, gas bubbles are developed pressure inside the volcano increases due to trapped bubbles within it.
•When pressure exceeds the strength of overlying rocks, fracturing occurs resulting in a further drop in pressure.
