Answer:

True

Step-by-step explanation:

Most of the volcanoes in Hawaii are basaltic shield volcano that erupts to release a basaltic magma known as tholeiite. There are different type of basaltic eruptions with varying composition . for example –

a) Tholeiite is a dominant extrusive releasing magma from volcanoes in Hawaii

b) Another type is Mid-Ocean Ridge basalts that are formed at ocean spreading centers and consists of more than 95% tholeiitic in composition

c) Alkali basalt is a rarer basalt type which are released during the pre- and post sheild stages of the life of a volcano.

d) Ocean Island Basalt consists of trace elements such as Th, U, Ba, Pb, the Rare Earth Elements etc

Hence, Lava flowing from volcanoes in Hawaii is basaltic magma.
