Imagine you are planning a safety drill for your school because of a nearby volcano. Based on the learning objectives, what important information should you include in your plan?

• Volcanic landforms and safety measures

• The history of volcanoes

• The names of all volcanoes in the world

• The temperature of lava

What is a volcano?

• An opening in the Earth's crust where magma escapes as lava, ash, and gases

• A large mountain formed by wind erosion

• A deep ocean trench formed by tectonic plates

• A valley created by river erosion

What is the first step in the volcanic eruption process?

• Pressure builds

• Eruption occurs

• Magma formation

• Ash falls

Which of the following best describes what happens when pressure builds during a volcanic eruption process?

• Rock melts beneath the Earth's crust

• Gases and pressure accumulate, forcing magma upward through cracks and conduits

• Magma erupts through the vent as lava

• Ash settles on the ground

What is released during the eruption stage of a volcanic eruption?

• Only water vapor

• Only rock fragments

• Lava, ash, gases, and rock fragments

• Only magma

Which volcano is an example of a dormant volcano?

• Mount Fuji in Japan

• Mount Kilimanjaro in Tanzania

• Barren Island in India

• Mount Popa in Myanmar

What is a caldera?

• A cone-shaped mountain formed by eruptions

• A large circular depression formed when a volcano collapses after a major eruption

• A vast area covered by lava flows

• An island formed by underwater volcanoes

Which volcanic landform is formed when underwater volcanoes build up enough material to rise above sea level?

• Lava Plateaus

• Volcanic Islands

• Cone-Shaped Mountains

• Calderas

Lava plateaus are best described as:

• Large circular depressions formed after eruptions

• Classic volcano shapes with steep sides

• Vast areas covered by successive lava flows that spread horizontally over great distances

• Islands formed by volcanic activity

What is Japan's highest mountain and an active volcano that last erupted in 1707-1708?

• Mount Etna

• Mount Fuji

• Mount Kilimanjaro

• Mount Vesuvius
