What forms when magma cools? Magma Transformation: Magma is molten rock and can be found below the Earth's surface and above the Earth's surface. When above, it is called lava. Magma can cool when it's both inside the Earth and outside the Earth. ...
Although they differ in composition, both are types of igneous rock that forms when magma cools and solidifies. Granite forms when magma with a high silica content cools slowly deep beneath Earth's surface; basalt forms when magma with a low silica content cools quickly outside of or very ...

millions of years, the magma beneath the dome cools and hardens into a solid core. During the same period, erosion wears away the softer materials on top, leaving the rugged, harder material beneath exposed as an upwarped mountain. Spotlight on famous forms ...
Volcanic craters are formed as a result of volcanic eruptions. This is where hot magma flows and when it cools, it forms Ignatius rocks. Sometimes lakes are formed on the craters and are referred to as crater lakes, such as Blue Lake Crater in the United States....
When it reaches about 70 miles (112 kilometers) into the mantle, high temperature and pressure melt the rock at the edge of the plate, forming thick, flowing magma. Since it is less dense than the rock that typically surrounds it deep underground, magma tends to rise toward Earth's ...
feeds a hot spring passes through rocks underground, it may dissolve minerals from the rocks and bring them to the surface. If those rocks are volcanic, then the water carries silica to the surface. (Silica is the most abundant element found in magma.) At the surface, the water cools and...
