Type of Volcanos
The type of volcano that is formed by pyroclastic fragments like ashes, and solid lava pieces.
what is a Cinder cone volcano
A fault in which the block above the fault has moved down relative to the block below
What is a normal fault
What are the main types of volcanoes
The main types of volcanoes are shield volcanoes, composite (stratovolcanoes), cinder cone volcanoes, and lava domes. Each has a different shape and eruption style.
What causes earthquakes
Earthquakes are caused by the sudden release of energy in the Earth's crust due to the movement of tectonic plates. This release of energy creates seismic waves that make the ground shake.
What is a tsunami
A tsunami is a series of large ocean waves usually caused by an underwater earthquake, volcanic eruption, or landslide that displaces a large amount of water.
A volcano built of of layers of lava and ash
What is a Stratovolcano
A fault in which one side of it "The Hanging wall" moves up and over the other side "The Foot Wall
What is a Reverse fault
What determines how explosive a volcanic eruption is
The silica content and gas content of the magma determine the explosiveness. High silica and gas levels make eruptions more explosive, while low silica magma leads to quieter lava flows.
What is the Richter scale
The Richter scale is a logarithmic scale used to measure the magnitude (energy released) of an earthquake. Each whole number increase represents a tenfold increase in amplitude and about 32 times more energy release.
How fast can a tsunami travel
Tsunamis can travel at speeds of up to 500 to 800 kilometers per hour (about 310 to 500 miles per hour) in deep ocean water.
A volcano that has gentle slopes that has a wide base and is lying flat on earth.
What is a Shield volcano
A fault in which walls of rock grind past each other in opposite directions.
What is a Strike-slip fault
What is a caldera
A caldera is a large, bowl-shaped depression that forms when a volcano collapses after a major eruption that empties the magma chamber.
What is the difference between the epicenter and the focus of an earthquake
The focus (or hypocenter) is the point inside the Earth where the earthquake starts, while the epicenter is the point directly above it on the Earth's surface.
What are the warning signs of a tsunami
Warning signs include a strong earthquake, a sudden rise or fall in coastal water levels, and a loud ocean roar. If the sea suddenly recedes, it may be a sign a tsunami is approaching.
A large depression when a volcano erupts then collapses.
What is a Caldera volcano
A fault in which the two blocks on either side of the fault move in two different directions at the same time.
What is a Oblique fault
How do shield volcanoes differ from composite volcanoes
Shield volcanoes have gentle slopes and produce fluid lava flows, while composite volcanoes are steeper and have alternating layers of lava and ash due to more explosive eruptions.
Can earthquakes be predicted
No, earthquakes cannot be predicted with precise accuracy. Scientists can estimate where they are likely to happen based on fault lines and past activity, but exact timing and magnitude cannot be predicted.
Why are tsunamis so dangerous
Tsunamis are dangerous because they bring powerful waves that can flood coastal areas, destroy buildings, sweep away people and vehicles, and cause massive loss of life and property.
Formed from the very slow extrusion of highly viscous silica lava
What is a lava dome
what is the most famous fault.
What is the San Andreas fault
What is volcanic ash and how does it affect the environment
Volcanic ash is made of tiny rock and glass particles ejected during eruptions. It can damage crops, contaminate water, disrupt air travel, and cause respiratory problems.
5. What should you do during an earthquake
During an earthquake, you should Drop, Cover, and Hold On. Get under sturdy furniture, protect your head and neck, and stay indoors away from windows and heavy objects that could fall.
What should you do if there is a tsunami warning
You should move to higher ground immediately, stay away from the coast, and listen to emergency alerts. Do not return to the shore until authorities say it is safe.
