Scientists Say: Magma and lava

Magma (noun, “MAG-muh”), Lava (noun, “LAH-vuh”)

Each of those phrases describe molten rock. The distinction is the place that melted rock is positioned. Magma is molten rock deep underground. A lot of Earth’s mantle is product of magma. That magma can stand up by way of Earth’s crust and erupt out of volcanoes. Molten rock that has reached Earth’s floor is known as lava. Relying on its chemical composition, lava may be runny like syrup or so thick it barely flows in any respect. This molten materials remains to be known as lava as soon as it has cooled and hardened. The stable rock is named igneous rock. The formation of igneous rock is a part of Earth’s rock cycle. On this cycle, plate tectonics, weathering and different processes frequently rework Earth’s rocks from one kind to a different. The three varieties are igneous, sedimentary and metamorphic rock.

In a sentence
