As magma heats in the middle, it becomes______ and begins to_____. this results in the magma traveling to the crust where it cools and becomes______ rock.
first blank: less dense, solid, more porous
second blank: sink, rise, break apart
third blank: sedimentary, igneous, metamorphic
As magma heats in the middle, it becomes more porous and begins to rise. This results in the magma traveling to the crust where it cools and becomes igneous rock.
As magma heats in the middle, 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 the question, we need to understand the process of how magma moves and cools.
First blank: As magma heats in the middle, it becomes less dense. Due to the increase in temperature, the magma's density decreases, causing it to become less dense compared to the surrounding material.
Second blank: As a result of becoming less dense, the magma begins to rise. This is because it experiences buoyancy, similar to how a less dense object floats in a denser medium. The hotter magma rises through the Earth's crust towards the surface.
Third blank: When the magma reaches the crust and cools, it solidifies and becomes igneous rock. Ignous rocks are formed from the solidification of molten material (such as magma) either above or below the Earth's surface. Therefore, the correct choice for the third blank is "igneous."
To summarize:
- First blank: less dense
- Second blank: rise
- Third blank: igneous rock
