Rock Transformations

ANY rock can become a new sedimentary rock when ________.

• Sediment is melted and then cooled

• Sediment is compacted and cemented together

• Magma is melted and cooled

• Magma is compacted and compressed

ANY rock can become a new igneous rock when ___________.

• Sediment is melted and cooled

• Magma is melted and cooled

• Magma is compacted and cemented

• Sediments are compacted and compressed

ANY rock can become sediments through the process called ________ and that process happens because of ________.

• melting and cooling, energy from the sun

• melting and cooling, energy from the interior of the Earth

• weathering and erosion, energy from the sun

• weathering and erosion, energy from the interior of the Earth

ANY rock can become magma through the process called ________ and that process happens because of ________.

• melting, energy from the sun

• melting, energy from the interior of the Earth

• weathering, energy from the sun

• weathering, energy from the interior of the Earth

Two rocks formed at the same time. One was made from magma that cooled and the other was made from sediments that were compacted and cemented.

The rocks are _______.

• Different because they formed in different places.

• Different because they formed in different ways.

• The same because they formed at the same time.

• The same because they are both made of rock material.

You observe two rocks. Rock 1 is from Arizona and Rock 2 is from Kentucky.

Rock 1: Formed from liquid rock.

Rock 2: Formed from small pieces of rock

Rocks 1 and 2: Formed at about the same time.

The rocks are _____________.

• Different because they formed in different ways.

• The same because they formed at about the same time.

• Different because they were formed in different places.

• The same because they both formed from rock material.

Mr. Donnelly shows you a rock that Connor brought to class. It is from California and it formed from liquid rock. He also shows you a rock brought in by Angela. That rock has layers and formed from sediments. Both rocks are 1,500,000 years old.

The rocks are ______________.

• different types because they formed in different places.

• the same because they formed at the same time.

• different types because they were formed in different ways

• the same because they were both formed from rock material.

True or false:

Energy changes igneous rock into liquid rock and changes sedimentary rock into small pieces of rock.

• True

• False

True or False:

Energy from different sources leads to different types of rock.

• True

• False

How can energy play a role in forming different types of rock?

• Energy causes different types of rock to change in different ways. Energy changes igneous rock into liquid rock and changes sedimentary rock into small pieces of rock.

• Energy caused one rock type to form, but not the other. Rock that forms because of energy is a different type of rock than rock that forms without energy.

• Energy from different sources leads to different types of rock. Energy inside Earth melts rock into liquid rock, but energy from the sun causes rock to weather into small pieces of rock.

• Energy changes rock on different continents in different ways. Each continent on Earth has different rock that might form liquid rock or small rock pieces when exposed to energy.
