The Rock Cycle
The process through which the 3 main rock types (igneous, sedimentary, metamorphic) transform from one type to another.
What is the rock cycle?
a scientific theory explaining that Earth's crust and upper mantle are broken into large, irregularly shaped plates that move and interact
What is plate tectonics?
The movement of thermal energy from one object to another of different temperature.
What is heat transfer?
The settling of eroded rock into a final location.
What is depostion?
What is a landform?
The breaking down of rock and moving of it to a new location.

What is weathering & erosion?
Who is Alfred Wegener?
The 2 forms of heat transfer that require direct contact.
Grinding away rock by friction or impact.
What is abrasion?
Large piles of sand deposited by wind.
What are dunes?
The type of weathering in which the rock material is changed into another substance.
The 3 types of boundaries formed by tectonic plates.
What are convergent boundaries, divergent boundaries, and transform boundaries?
The 3 forms of heat transfer.
a long zipperlike chain of underwater mountains formed by divergent boundaries.
What are mid-ocean ridges?
Provide 3 examples of a bowl shaped basin that is filled with ground water.
(100 points for each correct answer)
Lake superior, Huron, Michigan, Ontario, etc.
How are sedimentary, igneous, and metamorphic rocks formed?
Sedimentary rocks are formed by weathering erosion and deposition
Igneous rocks are formed by the melting and cooling of rock
Metamorphic rocks are formed by heat and pressure
the sideways and downward movement of the edge of a plate of the earth's crust into the mantle beneath another plate.
What is subduction?
What is formed by the rising and falling of a fluid as heat is transferred into it.
What is a convection current?
What is pangea?
The landform formed by the colliding of a convergent boundary. Name 3 exapmples.

What is a mountain?
Everest, Killimanjaro, The Rocky Mountains, The Andes, The Alps, etc.
provide 5 ways in which rocks can be weathered.
frost action, plant/root action, abrasion, burrowing animals, water, oxygen, CO2, acid rain
3 pieces of evidence that Pangea existed.
1. Mountain ranges in Africa and South America appearing the sane as if they were formed at the same time
2. Coal deposits formed by the remains of tropical plants found in places that cant support that life
3. Fossil records of the Mesosaurus in Africa and South America; the organism would not be able to swim across the atlantic ocean
Conduction - heat from the cup transferred to your hands
convection - the steam coming off the cup is an example of a heated fluid
Radiation: being able to feel the heat coming from the mug even before making contact
the sideways and downward movement of the edge of a plate of the earth's crust into the mantle beneath another plate.
what is subduction?
A landform that is formed by divergent boundaries that creates 2 high points of land split apart by a low sitting middle area.
Hint: Iceland
What is a rift valley?
