hazardous earth

• The Earth's crust is made up of several tectonic plates that move over the mantle.
• Convergent boundary - Two plates colliding with each other
• Plate boundaries are areas where two or more plates meet, resulting in different types of plate movements such as divergent, convergent, and transform boundaries.
• Divergent boundary - Two plates moving away from each other
• Earthquakes are sudden movements or vibrations caused by the release of energy from within the Earth.
• Plate tectonics refers to the movement of these plates, which can cause earthquakes, volcanic eruptions, and other geological events.
• Divergent boundary - Plates moving away from each other, creating new material
• Transform boundary - Plate sliding past one another
• Plate movement can cause earthquakes when two plates rub against each other or if they suddenly stop moving.
• Divergent Boundary - Plates moving away from each other (constructive)
• Volcanoes are openings on the surface of the Earth through which molten rock (magma) and gases escape.
• Tsunamis are large waves generated by earthquakes underwater.
• Tsunamis are large waves generated by underwater earthquakes, landslides, or volcanic activity.
• Volcanoes are formed at subduction zones when magma rises through cracks in the overriding plate.
• The San Andreas Fault is an example of a transform fault where the Pacific plate slides over the North American plate.
• Seismographs measure ground shaking during earthquakes using seismometers that record acceleration, velocity, and displacement data.
• Shield Volcanoes - Low-lying with gentle slopes, formed by repeated lava flows over long periods of time
