Select the correct answer from the list.(2 points)
As magma heats in the mantle, it becomes _____ (more porous, solid, less dense)and begins to_____ (rise, sink, break apart). This results in the magma traveling to the crust where it cools and becomes ______ (metamorphic, sedimentary, igneous) rock.
As magma heats in the mantle, it becomes less dense and begins to rise. This results in the magma traveling to the crust where it cools and becomes igneous rock.
To answer this question, we need to understand the process of magma formation and how it transforms into rock.
1. As magma heats in the mantle, it becomes ____ (more porous, solid, less dense):
Magma is a molten rock mixture consisting of various elements and minerals. As it heats up, it becomes less dense. So, the correct answer would be "less dense."
2. Magma then begins to _____ (rise, sink, break apart):
Due to its lower density, magma tends to rise. This is because it is lighter than the surrounding denser rocks in the mantle. Therefore, the correct answer would be "rise."
3. This results in the magma traveling to the crust where it cools and becomes ______ (metamorphic, sedimentary, igneous) rock:
When magma reaches the Earth's crust, it cools down and solidifies, forming rock. The type of rock formed depends on the cooling rate and the composition of the magma. In this case, since we are talking about the transformation of molten magma into solid rock, the correct answer would be "igneous."
So, to answer the question:
1. As magma heats in the mantle, it becomes less dense.
2. It then begins to rise.
3. This results in the magma traveling to the crust where it cools and becomes igneous rock.
