VOLCANOES

Volcano:
An opening in the ground where molten rock and gas is erupted

• Volcano
• A vent where molten rock and gases arr erupted from the earth's interior

I focused on researching strategies and information on volcanoes, including cause, effect, mount st helens, and why volcanoes erupt violently

RESEARCH PROCESS

• Before starting researching i knew that natural disasters were catastrophic events that were caused by nature
• I knew that research meant using many different sources and taking notes
• Before starting this unit i expected to learn about how all disasters were caused

RESEARCH PROCESS CONTINUED

• I hoped to learn how pressure builds up in earth's mantle which leads to violent volcano eruptions

CAUSES OF VOLCANOES

• Magma formed by molten rock is forced to the surface by pressure
• Volcanic rock builds up around the opening and over time it becomes a mountain

EFFECTS OF VOLCANOES

• Volcanoes can destroy nearby civilizations
• Volcanoes can release harmful gases into the atmosphere and make the climate cooler
• Earthquakes and wildfires can be caused by volcanic eruptions

MAJOR OCCURENCE: mount st helens-1857

• from march on earthquakes a series of small earthquakes were recorded almost daily
• eruption occured on may 18, 1857
• 62 people were killed (mostly ones who got into restricted area)

MY RESEARCH QUESTION: why do volcanoes erupt violently?

• Pressure builds up under earth's crust
• heat melts rock and heats up gases
• magma and gases need to escape from earth's interior

research process: obstacles and breakthroughs while researching

• sometimes i struggled with finding the information i needed, but i worked through it
• i will use cornell notes and the outline to take notes in the future
• i will avoid using non-credible sources
• i will also avoid getting mad because i couldn't find what i needed

research process: stages of the research

• take notes on several different resources
• sort out the relevant and irrelevant information
• organize information by category/topic
• summarized information into powerpoint slides
• Cite sources
