|
Magma Formation: Heat from the Earth's mantle melts rock, forming magma beneath the crust.
|
Magma Rise: Because magma is less dense than surrounding rock, it rises through cracks and magma chambers toward the surface.
|
|
Pressure Build-up: Gases dissolved in the magma (like water vapor, CO₂) build up pressure inside the magma chamber.
|
Fracturing of Rock: Increased pressure causes cracks and fractures in the Earth’s crust, creating pathways for magma to move upward.
|
|
Eruption: Magma, along with gases and ash, is forcefully expelled through a volcanic vent, resulting in an eruption.

Physical ->Temperature, weather, freeze-thaw action
|
Chemical -> Acids, Acid Rain
|
|
Biological -> Buildings, deforestaion
|
|
|
Magma cools and solidifies → forms Igneous rock
|
Igneous rock breaks down into sediments through weathering and erosion → sediments get compacted
|
|
Sedimentary rock is subjected to heat and pressure deep underground
|
Metamorphic rock melts into magma
|
|
Magma is molten rock that is still beneath the Earth's surface.
|
Lava is molten rock that has reached the Earth's surface during a volcanic eruption.
|
|
Magma contains gases, crystals, and dissolved minerals.
|
Some gases escape when it becomes lava.
|
|
Igneous -> Formed from cooling and solidification of magma or lava. Ex: Basalt, Granite.
|
Sedimentary -> Formed from layers of sediments that are compacted and cemented over time. Ex: Limestone, Sandstone.
|
|
Metamorphic -> Formed when existing rocks are changed by heat and pressure. Ex: Marble, Gneiss.

|
Detects ground vibrations caused by earthquakes or other seismic activities.
|
Measures the strength (magnitude) of an earthquake.
|
|
Records the duration and timing of seismic waves.
|
Helps determine the earthquake’s epicenter (location on Earth's surface directly above the origin).
|
|
Assists in early warning systems to reduce damage and save lives.
