What is made up of hot, molten rock beneath the Earth's crust?

• VOLCANO

• LAVA

• MAGMA

• CHAMBER

Volcanic magma's chamber has a high amount of silica. What might happen if a volcano erupts?

• Non-explosive eruptions might happen.

• Magma will become hard beneath.

• Explosive eruptions might occur.

• Lava will flow slowly.

Which statement differentiates picture A from picture B in Figure 3 below?

• Picture A is inactive because it has no sign of eruption, while picture B is active because it has a sign of eruption.

• Picture A is inactive because it has a sign of eruption, while picture B is active because it has no sign of an eruption.

• Picture A is an active volcano because there is no sign of eruption, while picture B is inactive because it indicates eruption.

• Picture A is an active volcano because it has a sign of eruption, while picture B is an inactive volcano because it has no sign of an eruption.

Which statements differentiates a mountain from a volcano?

• A mountain has a steep slope that doesn't erupt, while a volcano has a vent in which magma flows.

• A mountain has craters through which gases come out, while a volcano has magma beneath.

• A mountain lava hardens for a long time, while a volcano is a steeply inclined slope.

• Both geological structures have erupted hot molten materials and turned them into lava.
