SCIENTIFIC METHOD
Which tool is used in order to find the MASS of an object?
Is eye color an inherit trait or an acquired trait?
Inherit
Which layer of Earth has the LEAST density?
Which term refers to the distance from any point on a wave to an identical point on the next wave?
a) wavelength
A fossils or rock's age compared to something else is known as
Relative Age
Which term BEST describes the factor in an experiment that the scientist changes or manipulates?
a) independent variable
A plant evolves new methods to attract animals. At the same time, the animal evolve in new parts to help the plant pollinate. This is an example of
Coevolution
Which type of rock forms from magma erupting from a volcano?
c) igneous
Which term refers to the maximum distance that the particles in a wave move from their rest position?
List two major causes of mass extinction
climate change, volcanic eruptions, asteroid impact
These are the steps of the Scientific Method
Ask a question, State a Hypothesis, Plan the Experiment (variables), gather data, analyze data and draw conclusion.
An organism that gets energy by eating other organisms.
Consumer
In which layer of Earth are temperature and pressure the highest?
a) inner core
A lizard sunbathing on a rock. Convection or radiation?
Radiation
Why is it difficult for scientists to reconstruct the history of life during Precambrian time?
Life was simple and it did not fossilized well or if it did, it did not last. Time and the rock cycle has destroyed them.
How many independent variables should there be when testing a hypothesis?
a) one
A palm tree is an example of this type of organisms (hint: it makes its own food)
Producer
Which is the BEST description of where earthquakes are likely to occur?
c) along transform plate boundaries
In which type of wave do particles move back and forth in the same direction that the wave travels?
b) longitudinal wave
What is an unconformity and what causes it?
A gap in the record (or layers of rocks). Caused by erosion, folds, faults or earthquakes.
You want to know how different types of sugars affect the color of the cake (darker or lighter). What is the dependent variable and the independent variable.
Independent = types of sugar
Dependent = color of the cake
An organism that breaks down dead material and returns the substances to the environment.
Decomposer
Which of these BEST describes the composition of Earth's inner core?
Mention the 3 ways in which heat transfers.
Conduction (contact), convection (in fluids) and radiation (through space)
Explain the law of superposition.
In undisturbed rock layers, the oldest ones are at the bottom and the younger ones at the top.
