Igneous Rock
Describe how igneous rocks are formed.
From lava and magma
heat and pressure underground
The grand canyon is made up of this type of rock.
What is sedimentary rocks.
Naturally occurring SOLID mixture that makes up earths crust.
rocks
This process makes metamorphic rocks
heat and pressure
Name 2 examples of igneous rock.
basalt and obsidian
Name 2 examples of metamorphic rock
marble and gneiss
compaction & cementation
Deposition & lithification
what can only be found in sedimentary rock
smaller rocks, pebble, fossils, sand
This process turns rocks in magma
melting
Describe the difference between magma and lava.
Magma is found inside the Earth, while lava is found at or near the Earth's surface. Both are liquid or molten rock.
Describe how a sedimentary rock can become a metamorphic rock
being pushed underground with heat and pressured applied
