Definitions
- Referring to molten rock that has flowed out of a volcano and solidified on the surface. - Talking about the red-hot liquid that spews out of a volcano during an eruption. - Describing the hardened rock formed by the solidification of molten lava.
- Referring to molten rock beneath the Earth's surface. - Talking about the hot, semi-liquid material that can cause volcanic eruptions. - Describing the mixture of molten rock, crystals, and gases that can be found in the Earth's mantle.
List of Similarities
- 1Both are forms of molten rock.
- 2Both can be found in or near volcanoes.
- 3Both can cause volcanic eruptions.
- 4Both are composed of similar minerals and elements.
- 5Both can solidify and form rocks.
What is the difference?
- 1Location: Lava is molten rock that has flowed out of a volcano and solidified on the surface, while magma is molten rock beneath the Earth's surface.
- 2Temperature: Lava is hotter than magma due to the cooling that occurs when it reaches the surface.
- 3Pressure: Magma is under more pressure than lava because it is located deeper within the Earth's crust.
- 4Appearance: Lava is typically red or orange in color, while magma is usually black or dark brown.
- 5Movement: Lava flows on the surface, while magma moves slowly beneath the Earth's surface.
Remember this!
Lava and magma are both molten rock, but they differ in location, temperature, pressure, appearance, and movement. Lava is the term used for molten rock that has flowed out of a volcano and solidified on the surface, while magma refers to molten rock beneath the Earth's surface. Lava is hotter than magma due to the cooling that occurs when it reaches the surface, and magma is under more pressure than lava because it is located deeper within the Earth's crust.
