Luke has been studying how volcanic lava changes the landscape around a volcano. He has been learning about the rock cycle at school from his amazing teacher Mr. Galer and draws a model to describe how new rock might be formed.

His model is incorrect what corrections should be made?

• In Luke's model, underground melted rock should be labeled magma

• The sedimentary rock should be labeled magma

• The molten rock flowing down the mountain should be labeled lava

• The volcano should be labeled mountain.

What type of rock is formed when molten rock cools?

• Sedimentary rock

• Igneous rock

• Metamorphic rock

• Sandstone

The two main types of igneous rocks are extrusive and intrusive. ​ (a)   are formed on the surface of the Earth from lava, which is magma that has emerged from underground. ​ (b)   are formed from magma that cools and solidifies within the crust of the planet.

• Extrusive rocks
• Intrusive rocks
• Sedimentary rocks
• Metamorphic rocks

• igneous

• sedimentary

• metamorphic

• bioclastic

You are discussing the rock cycle with your friend Alyson. She claims that in the rock cycle, sedimentary rock does not always change to form metamorphic or igneous rock. Which explanation best describes whether you agree or disagree with Catalina?

• Catalina is correct because the sedimentary rock could melt and cool to reform a new sedimentary rock.

• Catalina is correct because the sedimentary rock can be weathered and eroded to form sediment which then reforms new sedimentary rock.

• Catalina is incorrect because the rock cycle follows a set path. Sedimentary rock always forms metamorphic rock.

• Catalina is incorrect because in the rock cycle, rocks always change and form a new type of rock, they cannot stay the same.
