Magma is molten rock beneath the Earth's surface, while lava is molten rock that flows out of a volcano onto the Earth's surface. Essentially, magma becomes lava once it reaches the surface.

Magma
- Molten or semi-molten rock that exists beneath the Earth's surface. - Contains minerals, gases, and other materials. - High temperature (above 700°C or 1292°F). - Can form from the melting of rocks or the ascent of fluids. - Not directly observable or accessible.
Lava
- Magma that has erupted onto the Earth's surface. - Flows or erupts in various forms, such as fountains, flows, domes, or ash clouds. - Lower temperature than magma (around 600-1200°C or 1112-2192°F). - Composed of minerals, gases, and bubbles. - Can cause destruction and damage to infrastructure.
Key Differences:
- Location: Magma is underground, while lava is on the surface. - Temperature: Magma is hotter than lava. - Accessibility: Magma is not directly observable, while lava is. - Effects: Magma can cause volcanic activity, while lava flows can cause destruction.
