Question

fill in the blank:
directions: answer the following fill in the blanks. you can use the chart above and your notes to help.

1. metamorphic rocks are formed by applying

____________________ to any form of rock.

1. igneous rocks are formed by _________________ magma.
2. sedimentary rocks are formed by ____________________ individual

pieces of sediment.

1. magma is formed by ____________________ any type of rock
2. sediment is formed by ____________________ any type of rock

scenarios:
read the following scenarios. based on the description, decide if you have
discovered a metamorphic, igneous or sedimentary rock.
you discover a rock deep inside the earth. the rock has these beautiful
waves. in order to find this rock you needed to utilize special equipment to
withstand high temperatures and a high amount of pressure. which rock did
you discover?
blank
you discover a crystal rock next to a volcano. you know the volcano erupted
approximately 5 years ago. since the eruption, the volcano has been inactive
and the area has calmed down. what type of rock did you discover?
blank
you discover a rock. it is made out of many different types of rocks. it even
had a fossil inside of it. what type of rock did you discover?
blank

Explanation:

1. For fill-in-the-blanks: Based on rock formation processes:

• Metamorphic rocks form from heat and pressure on existing rocks.
• Igneous rocks form from cooling and solidifying magma.
• Sedimentary rocks form from compacting and cementing sediment pieces.
• Magma forms from melting existing rock.
• Sediment forms from weathering and eroding existing rock.

1. For scenarios:

• Deep Earth, high temp/pressure = metamorphic rock.
• Near recently erupted volcano = igneous rock (from cooled magma).
• Mixed rock pieces + fossil = sedimentary rock (sediment accumulates and preserves fossils).

Answer:

Fill in the Blank:

1. heat and pressure
2. cooling and solidifying

4. melting
5. weathering and eroding

Scenarios:

1. Metamorphic rock
2. Igneous rock
3. Sedimentary rock
