Rock cycle
Includes sand, pebbles, bones, and shells
Sediment
A scientific explanation for an observation that can be tested by further investigation. An "If...Then" statement
hypothesis
Heat transfer through touch
process of wearing down rock by friction - usually due to water or wind
abrasion
small, solid pieces of material that come from weathered rocks or living things
Sediment
Formed from heat and pressure
Metamorphic Rock
steps followed to solve problems: collecting data, formulating & testing a hypothesis, & stating conclusions.
scientific method
How does Radiation move
Heat transfer through Electromagetinc waves
process in which layers of rock gradually break off as pressure is released from the rock
exfoliation
rain, sleet, or snow that contains a high concentration of acid
Acid Rain
Means "to change"
Metamorphic Rock
The variable that is being changed (manipulated) by the experimenter.
independent variable
Flow of energy from one thing to another.
Heat
the repeated freezing and thawing of water in rocks that causes the rock to split apart
ice wedging
A large sheet of moving ice that covers a large part of a continent and can smooth or flatten the landscape
Glacier
Formed from compaction and cementation of sediments
Sedimentary Rock
The variable that reacts (responds) to what you have changed (manipulated).
dependent variable
Energy that speeds up molecules?
Thermal Energy
the process by which rocks break down as a result of chemical reactions
Chemical Weathering
The movement of rock material from one place to another.
Erosion.
What can be found in sedimentary rocks that is not found in the other two types?
Organic Material
A variable that is not changed in an experiment
constant
Materials that transfer energy easily.
the process by which rocks break down as a result of chemical reactions
Chemical Weathering
A large mass of slow-moving ice
