Why should an experiment be repeated at least 25 times?
Repeating ensures the results are consistent and reliable.
Repeating allows the scientists to get better at doing it.
Repeating allows scientists to throw out trials not matching.
Repeating shows if the experiment is good or not.
How is repetition different from replication?
Repeat: one chart; Replicate: several charts
Repeat: use a calculator; Replicate: use a computer
Repeat: same scientist; Replicate: other scientist
Repeat: based on observations; Replicate: based on evidence
What should happen to newly discovered information?
Should be thrown out if it doesn't fit
Scientists must be wrong, so repeat experiment.
Scientists should make info. agree with current theory.
Theory changed to consider new information.
How can a scientists best add to evidence already gathered about a topic?
Research on the internet
Debate research with other scientists
Write an opinion column about the research
Make and record new observations

Intrusions
What does the Principle of Superposition decree?
Youngest layers of rock contain fossils.
Oldest layers of rocks are on the bottom.
Oldest layers of rock will be primarily igneous rock.

What is the grinding of rock by friction or impact called?
Abrasion
Erosion
Oxidation
Decomposition
Which area experiences the most wind erosion?
Grasslands
Deserts
Temperate forests

Differentiate mechanical weathering and chemical weathering.
Chem: shorter time frame; mechanical: longer time frame
Chem: in tropics; Mechanical: in temperate climates
Chem: in the mountains; Mechanical: on flat surfaces
Chem: changes rocks' materials; Mechanical: changes shape
What does "rivers erode rocks" mean?

Rivers wear away rocks.
Rivers cover up rocks as they grow deeper.
Rivers gradually sharpen rocks.
Which is NOT found in Florida?

What happens when a river enters a large body of water?
Water slows and deposits large amounts of sediment.
Water increases speed and carries sand to middle of ocean.
Water flows over the delta, causing rippling.
Water erodes the shoreline and deposits barrier islands.
