Question | Answer |
What are the three types of boundaries? | The three types of boundaries are divergent, convergent, and transform. |
What are the three types of stress? | The three types of stress is shearing, tension, and compression. |
What are the three types of faults? | The three types of faults are strike-slip, normal, and reverse faults. |
What is the difference between tidal waves and tsunamis? | The difference between tidal wave and tsunamis is that tidal waves are caused by the Moon's gravitational pull. But tsunamis are caused by earthquakes. |
_____ is when the volcano appears to be sleeping. | Dormat |
True or False? A chain of volcanoes around the Pacific Plate is called the Circle of Fire. | False |
What is silica? | Silica is a combination of oxygen and silicon. |
What are the three types of volcanoes? | The three types of volcanoes are cinder cone, shield, and stratovolcano volcano. |
What are the three types of lava flows? Describe each types. | The three types of lava flows is pahoehoe aa, and pyroclastic. Pahoehoe is a fast moving hot lava. thick. Aa is a cooler and slower moving lava. Pyroclastic is magma that get clogged up in the pipe then it explodes. |
What is a vent? | This is were magma goes through to release lava. |
What is a crater? | A crater is the opening were the lava goes through to reach the surface. |
What is a pipe? | The pipe is were the stored magma goes through to reach the vent. |
What is a magma chamber? | The magma chambers is weer most of the magma is stored. |
What is a side vent? | The side vent is were small amounts of magma reach the surface through the side of the volcano. |
True or False? An extinct volcano is a volcano that is very unlikely to erupt. | True |
A ______ ____ is what forms when magma in a volcano's pipe cools off. | Volcano neck |
What is the Ring of Fire? Why are there so many volcanoes there? | The Ring of Fire is a major form of a volcanic belt. There are so many volcanoes there because it is on a plate tectonic, which is where most volcanoes are formed. |
Where do most volcanoes occur? | Most volcanoes occur on the divergent plate boundary that are in the ocean. |
Explain in detail how the Hawaiian islands were formed. | The Hawaiian island was formed when a volcano erupted. It covered the ocean that is surrounded with hot lava. Soon it cooled down, creating a hard shell over the sea. This is how the Hawaiian Island were formed. |
Compare and contrast pahoehoe and aa. | Pahoehoe and aa are both similar because they both come from volcanic activity. Pahoehoe and aa are different because pahoehoe is a fast moving hot lava, but aa is a cooler, slower lava. |
Why are pyroclastic flows so dangerous? | Pyroclastic flows are so dangerous because when a volcano’s magma becomes trapped in the pipe, it explodes when it erupts. This leads to heavy smog and thick and sticky lava. |
Explain the 3 stages of volcanoes. | The first stage of volcanoes is that it is active. This is when the volcano is erupting or shows signs of it. The next stage is dormant. This is when a volcano did not erupt for a long period of time, like sleeping, than erupts suddenly. |
Explain the 3 stages of volcanoes.
Continued | The last stage is extinct. This is the stage when the volcano is very unlikely to erupt. |
What are tectonic plates? | Tectonic plates are pieces of the Earth''s crust. Many natural disasters happen on the plate tectonics , such as volcanoes and earthquakes. |
What is a transform boundary? | The plates slide against each other in
opposite directions. Often in areas where there is a lot of earthquakes. |
What is a divergent boundary? | Where two plates move in opposite
directions.New crust is created and a ridge forms. |
What is a convergent boundary? | Where two plates come together or collide,
resulting in one plate diving under the
other. This results in a trench being made. |
What is stress? | Stress is a force on rock that changes
its shape or the amount of space that
it occupies. |
What is a fault? | A fault is a break in Earth’s crust where
slabs of rock slip past each other. |
True or false? Earthquakes are one of the most dangerous natural disasters. | True |
