Making Rocks
What are sedimentary rocks made of?
Sediment/Small pieces of rock.
What type of igneous rock forms inside the Earth's surface?
Intrusive
True or false: the rock cycle has to follow a specific order of events.
False
What are pieces of the crust and upper mantle that can move freely called?
Tectonic plates
What type of plate boundary occurs when plates move towards each other?
Convergent
What are igneous rocks made of?
Lava or magma
What type of igneous rock forms outside the Earth's surface?
Extrusive
What should go in the spot labeled A?
Sedimentary
True or False: the tectonic plates move about 2 inches per year.
False, 2 cm per year.
What type of plate boundary occurs when plates move away from each other?
Divergent
What happens to molten rock in order to form igneous rock?
Cools and solidifies
Clastic
What should go in the spot labeled D?
Magma/Lava
What is the process that likely moves tectonic plates by hot rock rising in the mantle due to heat from the core and then cooling as they reach the crust and sinking back down?
Convection
What type of plate boundary occurs when plates move parallel to each other?
Transform
What happens to small pieces of rock in order to form sedimentary rock?
Compacts and cements together.
What type of sedimentary rock can fossils be found in?
Organic
What should go in the spot labeled C?
Melting
What is the process that likely moves tectonic plates by forming new rock between divergent plate boundaries creating a downhill path for the plates to fall and pushing the old rock away from the boundary?
Ridge Push
What type of landforms are created by convergent plate boundaries?
Mountains
What happens to rock in order to become metamorphic rock?
It undergoes a great change due to heat and pressure.
What type of sedimentary rock forms when minerals dissolve and then recrystallize?
Chemical
What should go in the spot labeled E?
What is the process that likely moves tectonic plates by having the front edge of the plate begin to sink and then gravity pulls the rest of the plate down into the mantle as well?
Slab Pull
What type of landforms are created at divergent plate boundaries?
Trenches, mid-ocean ridges, and volcanoes
