Rock Cycle
The process that turns sediment into sedimentary rock
What is compaction and cementation (pressure)
The outermost layer of the Earth
What is the crust
The process of breaking down rocks and Earth's materials
What is weathering
The theory that attempts to explain the movement of lithospheric plates
What are layers of rock called
The three main types of rocks
What are sedimentary, metamorphic, igneous
The layer of the Earth that is liquid
What is the outer core
The two types of weathering
What is chemical and mechanical
This type of boundary occurs when plates are moving apart
What is a divergent boundary
The law that states that younger rock sits on top of older rock
What is the law of superposition
This process describes the transformation of rock from one type to another
What is the rock cycle
The layer located between the crust and the outer core
What is the mantle (asthenosphere)
The process of moving weathered materials away
What is erosion
This is one effect of a convergent boundary
What is volcanoes, mountains, earthquakes, islands, OR deep ocean trenches
The process through which fossils can be used to determine the relative age of rock layers
What is events like ice ages, extinctions, formations of mountain chains, OR significant volcanic eruptions
This explains the contribution of melting to the rock cycle
What is igneous rock
The two elements that make up the core
What is iron and nickel
The three things that contribute to erosion
What is water, wind, and ice
This evidence supports the theory of plate tectonics
What is fossils, locations of volcanoes, land warping, ocean floor spreading OR continent shapes
These are used to define and identify geologic time periods
What is an index fossil
The importance of the rock cycle
What is recycling of Earth's materials
The movement within the mantle
What is convection currents
The process that deposits sediment in a new location
What is deposition
Convection currents in the mantle do this
What is cause plate movement
What is identifying and dating rock strata
