OUTSIDE EARTH
DAILY DOUBLE! the term for molten rock beneath earth's surface
What is magma?
The layer that is a combination of continental and oceanic crust.
What is the lithosphere?
What are preserved remains or traces of ancient organisms called?
What are fossils?
naturally occurring inorganic solid with a definite crystalline structure and specific chemical composition
What is a mineral?
A plate boundary that forms mountains
What is convergent plate boundary?
the San Andreas fault is this type of boundary
What is transform boundary?
This is a constructive (makes crust) geologic activity commonly found along the ring of fire.
What is volcanic eruption?
The rock type where fossils are usually found.
What is sedimentary (rocks)?
DAILY DOUBLE!
The 3 main types of rocks
What are igneous, metamorphic and sedimentary?
igneous rock formed on the earth's crust
What is extrusive?
the theory explaining why a scientist might find the same fossil on opposite sides of the ocean
What is the theory of plate tectonics?
Two types of rocks formed inside the earth.
What are igneous and metamorphic?
the timeline that shows Earth's history
What is Geologic Time Scale?
this type of rock is formed during seafloor spreading
What are igneous rocks?
A destructive (destroys or deforms crust) geologic activity found around the ring of fire.
What are earthquakes?
The rock type that is made from exposure to heat and pressure
What is metamorphic?
this causes tectonic plates to converge or diverge
What is convection currents in the asthenosphere?
Scientists use these methods to determine the age of rock layers
What is relative dating and/or radioactive dating?
these processes happen to all types of rocks
What is weathering, erosion and deposition?
this is a constructive activity, it involves magma, and is always underwater (except Iceland)
What is seafloor spreading
The term used to describe the mantle.
What is plasticity?
This determines the crystal size in igneous rocks
What is cooling time?
What law states that younger rock layers are on top of older layers?
What is Law of Superposition?
the continuous process that shows how rocks are turned from one rock type to another
What is the rock cycle?
