2. False

The statement "the eruptions of the Hawaiian volcanoes may be described as explosive in comparison to the 1980 Mount St. Helens eruption" is incorrect/false.


Mount St. Helens' magma is inherently more explosive than others like Hawaiian volcanoes. It has higher amount of water & silica (64% silica and about 4% water) and it delivered to the earth's surface at higher pressure 'cause of higher magma viscosity.
