Question

today, weathering and erosion are breaking these rocks down. in the future, the sediment from these rocks will form new rocks.
unalaska island, one of the aleutian islands
now, apply what you have learned about the rock cycle. complete the following statements.
many rocks in the aleutian islands are made from magma that cooled to become
rock over 50 million years ago.
in some instances, before the magma cooled and solidified through the process of
, it heated up water around it. this hot water then heated surrounding rock, causing some minerals to break down and form new minerals. this process formed
rock.
today, waves crash against the islands. these waves carry away sediment into the ocean in a process called
. over time, the sediment will settle to the seafloor and be buried,
, and cemented to form
rock.

Explanation:

To solve this, we use knowledge of the rock cycle:

First Blank:

Magma that cools (either intrusively or extrusively) forms igneous rock. So the first blank is "igneous".

Second Blank:

The process of magma cooling and solidifying is crystallization (or solidification, but crystallization is the key term for mineral formation from magma). So the second blank is "crystallization".

Third Blank:

When hot water (hydrothermal activity) alters surrounding rock, it forms metamorphic rock (metamorphism via contact metamorphism here). So the third blank is "metamorphic".

Fourth Blank:

Waves carrying sediment away is erosion (specifically, transportation via erosion). So the fourth blank is "erosion".

Fifth Blank:

After sediment settles, it is buried, then compacted (pressed together) before cementation. So the fifth blank is "compacted".

Sixth Blank:

Sediment that is compacted and cemented forms sedimentary rock. So the sixth blank is "sedimentary".

Answer:

s (filling each blank in order):

1. igneous
2. crystallization
3. metamorphic
4. erosion
5. compacted
6. sedimentary
