Question 9The islands of Hawaii are home to both dormant and active volcanoes. When the magmaof the active volcanoes reaches Earth's surface, it erupts as lava. The composition of lavaaffects its speed of travel and its physical appearance, forming distinct types.

Lava is the magma that is emerging on the Earth's surface. Lava flow depends on its magma composition, temperature, gas and crystal content, and eruption dynamics. Depending on the types of lava eruptions, different types of volcanic structures form.
