Volcano Types:
Volcanoes can be classified into three main types based on their activity levels: active, dormant, and extinct.
Active Volcano:
An active volcano is one that has erupted recently or is currently experiencing volcanic activity. These volcanoes pose a potential threat as they can erupt at any time.
Dormant Volcano:
A dormant volcano is one that is currently inactive but has the potential to erupt in the future. These volcanoes are considered to be asleep rather than extinct.
Extinct Volcano:
An extinct volcano is one that is no longer active and is unlikely to erupt again. These volcanoes have not erupted in thousands of years and are considered to be "dead."
Explanation:
The correct statement is that "Volcanoes can be active, dormant, or extinct." This statement is accurate because it correctly describes the different types of volcanoes based on their activity levels. The crust of the Earth is not made up entirely of volcanoes, and the magnitude of a tsunami is measured using the Richter scale. The liquid that comes out of a volcano is called magma when it is underground and lava when it reaches the Earth's surface. Understanding the different types of volcanoes is essential for predicting and preparing for volcanic activity and its potential hazards.

The correct statement among the given options is:
Volcano can be active, dormant, or extinct.
Explanation:
- Crust of the earth is made up of volcano: This statement is incorrect. The crust of the earth is not made up of volcanoes. The crust is the outermost layer of the Earth, consisting of solid rocks.
- Magnitude of tsunami is measured in Richter scale: This statement is incorrect. The magnitude of an earthquake is measured using the Richter scale, not the magnitude of a tsunami. Tsunamis are measured using other scales, such as the moment magnitude scale or the tsunami intensity scale.
- Volcano can be active, dormant, or extinct: This statement is correct. Volcanoes can be classified into three categories based on their activity levels:
- Active volcanoes: These volcanoes are currently erupting or have erupted within the last few decades.
- Dormant volcanoes: These volcanoes are not currently erupting but have the potential to erupt again in the future.
- Extinct volcanoes: These volcanoes are considered to be unlikely to erupt again in the future.
- The liquid that comes out of a volcano is magma: This statement is incorrect. The liquid rock that is found beneath the Earth's surface is called magma. When magma erupts from a volcano, it is then referred to as lava.
In conclusion, option C is the correct statement.
