17 Questions
What are the three types of volcanoes based on shape?
Shield, Cinder Cone, Composite
How many categories do volcanic eruptions have based on their intensity and characteristics?
Five
What determines if a volcano is classified as active or inactive?
Its record of eruption
How do examples like Mount Saint Helens and Mount Fuji help in understanding volcanoes?
They help visualize and understand the characteristics of different volcano types
Why are volcanoes essential for sustaining life on Earth?
To provide essential elements for life to thrive
Why is understanding different types of volcanoes and volcanic eruptions important?
To study and predict volcanic activity for risk mitigation
What are the five types of volcanic eruptions based on their intensity and characteristics?
Phreatic, Phreatomagmatic, Strombolian, Vulcanian, Plinian
Which type of eruption is characterized by violent explosions from the release of steam and gases?
Phreatic
How are active volcanoes differentiated from inactive volcanoes?
Active volcanoes show no activity and have no record of eruption, while inactive ones have erupted before.
What is the primary role of oceans and landforms in shaping weather and climate?
Absorbing energy from the Sun and redistributing it
What causes winds to move around the Earth in specific directions?
Heating from the Sun and Earth's rotation
Why is understanding different types of volcanoes and volcanic eruptions important?
To mitigate risks associated with volcanic activity
How does the reflectivity of the Earth's surface impact climate?
Light surfaces reflect more sunlight, leading to temperature changes.
What role do greenhouse gases play in climate change?
Greenhouse gases slow down the loss of heat from Earth, contributing to climate change.
How do alterations in greenhouse gas levels affect long-term climate patterns?
They contribute to shifts in long-term climate patterns.
How can reducing greenhouse gas emissions help mitigate climate change?
It can help in mitigating climate change by reducing heat retention.
What effect does the burning of fossil fuels have on the greenhouse effect?
It intensifies the greenhouse effect by increasing carbon dioxide levels.
