In a volcano, magma fills cracks in the Earth's crust. Under the right conditions, this magma can be forced onto the surface of the Earth in a volcanic eruption. What could cause a volcano to erupt?
O A
A chemical reaction occurs within the volcano causing the magma to boil.
ОВ.
Hot water under Earth's surface rises causing the magma to move upward.
O c.
Earth's plates move causing the heat and pressure of the magma to increase.
OD
The temperature of Earth's inner core rises causing the magma to expand.
