What is the difference between a volcano and a volcanic vent?

  1. A volcano is a mountain that has been formed by volcanic activity, while a volcanic vent is an opening in the Earth's crust through which magma and volcanic gases escape.

  2. A volcano is a large volcanic vent, while a volcanic vent is a small volcano.

  3. A volcano is a dormant or extinct volcanic vent, while a volcanic vent is an active volcano.

  4. There is no difference between a volcano and a volcanic vent.


Correct Option: A
Explanation:

A volcano is a mountain that has been formed by volcanic activity, while a volcanic vent is an opening in the Earth's crust through which magma and volcanic gases escape. Volcanic vents can be found on the sides of volcanoes, or they can be separate from volcanoes altogether.

What is the difference between lava and magma?

  1. Lava is molten rock that has erupted onto the Earth's surface, while magma is molten rock that is still beneath the Earth's surface.

  2. Lava is hot, molten rock, while magma is cold, solid rock.

  3. Lava is a type of volcanic rock, while magma is a type of igneous rock.

  4. There is no difference between lava and magma.


Correct Option: A
Explanation:

Lava is molten rock that has erupted onto the Earth's surface, while magma is molten rock that is still beneath the Earth's surface. Lava is typically hotter than magma, and it can flow more easily.

What is the difference between a volcanic eruption and a volcanic earthquake?

  1. A volcanic eruption is the release of magma and volcanic gases from the Earth's crust, while a volcanic earthquake is an earthquake that is caused by volcanic activity.

  2. A volcanic eruption is a sudden and violent event, while a volcanic earthquake is a gradual and gentle event.

  3. A volcanic eruption is a large event, while a volcanic earthquake is a small event.

  4. There is no difference between a volcanic eruption and a volcanic earthquake.


Correct Option: A
Explanation:

A volcanic eruption is the release of magma and volcanic gases from the Earth's crust, while a volcanic earthquake is an earthquake that is caused by volcanic activity. Volcanic earthquakes can be caused by the movement of magma beneath the Earth's surface, or by the collapse of volcanic structures.

What is the difference between a pyroclastic flow and a lahar?

  1. A pyroclastic flow is a fast-moving mixture of hot gas, ash, and rock fragments, while a lahar is a mudflow or debris flow that is caused by volcanic activity.

  2. A pyroclastic flow is a cold, slow-moving mixture of gas, ash, and rock fragments, while a lahar is a hot, fast-moving mudflow or debris flow.

  3. A pyroclastic flow is a type of volcanic eruption, while a lahar is a type of volcanic mudflow.

  4. There is no difference between a pyroclastic flow and a lahar.


Correct Option: A
Explanation:

A pyroclastic flow is a fast-moving mixture of hot gas, ash, and rock fragments, while a lahar is a mudflow or debris flow that is caused by volcanic activity. Lahars can be caused by the melting of snow and ice by volcanic heat, or by the remobilization of volcanic ash and debris by heavy rainfall.

What is the difference between a volcanic dome and a volcanic cone?

  1. A volcanic dome is a rounded, steep-sided hill that is formed by the accumulation of viscous lava, while a volcanic cone is a conical hill that is formed by the accumulation of loose volcanic material.

  2. A volcanic dome is a large, steep-sided hill, while a volcanic cone is a small, gently sloping hill.

  3. A volcanic dome is a type of volcanic eruption, while a volcanic cone is a type of volcanic landform.

  4. There is no difference between a volcanic dome and a volcanic cone.


Correct Option: A
Explanation:

A volcanic dome is a rounded, steep-sided hill that is formed by the accumulation of viscous lava, while a volcanic cone is a conical hill that is formed by the accumulation of loose volcanic material. Volcanic cones are typically formed by eruptions of low-viscosity lava, while volcanic domes are formed by eruptions of high-viscosity lava.

What is the difference between a caldera and a crater?

  1. A caldera is a large, basin-shaped depression that is formed by the collapse of a volcano, while a crater is a small, bowl-shaped depression that is formed by a volcanic explosion.

  2. A caldera is a deep, narrow depression, while a crater is a shallow, wide depression.

  3. A caldera is a type of volcanic eruption, while a crater is a type of volcanic landform.

  4. There is no difference between a caldera and a crater.
