Scientific Method
When the scientist change a variable in experiment based on that change he will measure the affect.
Independent variable
when others carry out someone else’s experiment and get the same results over and over again
Replication
he type of weathering in which rock is physically broken into smaller pieces
Physical Weathering
When you bake a cake it is
Chemical change
a landform made of sediment or Silt that is deposited where a river flows into an ocean or lake due to the slow down of the current.
a delta
A variable remain constant during an experiment
Controlled variable
a procedure carried out to carefully observe the natural world that may include making systematic observations, asking questions, gathering information, analyzing data, summarizing results, drawing conclusions, and communicating results; no hypothesis
investigation
the process by which water, ice, wind or gravity moves weathered particles of rock and soil
Erosion
Ice cream melting
Physical Change
a mound or ridge of sand or other loose sediment formed by wind, especially on the sea coast or in a desert
a dune
what is being measured; the factor that changes as a result of changes to the independent variable in an experiment
dependent variable
one person conducting the same, exact experiment over and over and over again
repetition
the process that breaks down rock through chemical changes
Chemical Weathering
Eating tacos
Chemical Change
a region in which a layer of limestone close to the surface creates deep valleys, caverns, and sinkholes
a karst
a procedure carried out to carefully observe the natural world that may include making systematic observations, asking questions, gathering information, analyzing data, summarizing results, drawing conclusions, and communicating results; no hypothesis
investigation
data and observations that are collected through scientific processes and that explain a particular observation
Empirical evidence
process in which sediment is laid down in new locations
Deposition
Oxidation of a bike makes it rusty
Chemical change
a cavity in the ground, especially in limestone bedrock, caused by water erosion and providing a route for surface water to disappear underground and collapse suddenly
Sinkhole
an educated guess; a possible explanation for a set of observations or an answer to a scientific question; must be testable
hypothesis
a representation of a complex object or process, used to help people understand a concept that they cannot observe directly
the principle that the total amount of matter is neither created or destroyed during any chemical or physical change
Law of conservation of Mass
breaking a glass in to pieces.
Physical change
the difference in elevation between the highest and lowest parts of an area
a relief
