WebMagma can be both sticky or less viscous. It depends on factors like temperature and amount of dissolved gas. The less viscous erupt and form porous rocks with fine grains while the more viscous ones form solid rocks with distorted grains. Melting The reverse of the previous process is melting. WebMagma is a hot liquid made of melted minerals. The minerals can form crystals when they cool. Igneous rock can form underground, where the magma cools slowly. Or, igneous …

WebThis magma then rises and can cause volcanic eruptions on the overriding plate. Earthquakes also occur along subduction boundaries, but they occur at different depths. The shallow earthquakes, which are usually less than 70 km deep, occur due to the movement of the overriding plate as it adjusts to the subducting plate. WebJun 30, 2024 · Magma is a type of lava that changes form through the rock cycle. Magma starts as gas, then it cools and crystallizes into igneous rocks like granite.
