Which tool is used in order to find the MASS of an object?

What is a triple beam balance

100

Is eye color an inherited trait or an acquired trait?

What is an inherited trait

100

Which layer of Earth has the LEAST density?

What is the crust

100

Which term refers to the distance from any point on a wave to an identical point on the next wave?

wavelength

100

A fossils or rock's age compared to something else is known as 

Relative Age

200

Which term BEST describes the factor in an experiment that the scientist changes or manipulates?

What is an independent variable

200

the process of water moving through plants and evaporating from the leaves and stems into the atmosphere

Transpiration

200

Which type of rock forms from magma erupting from a volcano?

igneous

200

Which term refers to the maximum distance that the particles in a wave move from their rest position?

amplitude

200

List two major causes of mass extinction

climate change, volcanic eruptions, asteroid impact

300

Ask a question, State a Hypothesis, Plan the Experiment (variables), gather data, analyze data and draw a conclusion.

What are the steps of the Scientific Method

300

An organism that gets energy by eating other organisms.

Consumer

300

In which layer of Earth are temperature and pressure the highest?

inner core

300

A lizard sunbathing on a rock. Convection or radiation?

Radiation

300

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. 

400

How many independent variables should there be when testing a hypothesis?

one

400

A palm tree is an example of this type of organisms (hint: it makes its own food)

Producer

400

Which is the BEST description of where earthquakes are likely to occur?

along transform plate boundaries

400

In which type of wave do particles move back and forth in the same direction that the wave travels?

longitudinal wave

400

What is an unconformity and what causes it?

A gap in the record (or layers of rocks). Caused by erosion, folds, faults or earthquakes.

500

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

500

An organism that breaks down dead material and returns the substances to the environment. 

Decomposer

500

Which of these BEST describes the composition of Earth's inner core?

solid iron and nickel

500

Mention the 3 ways in which heat transfers. 

Conduction (contact), convection (in fluids) and radiation (through space)

500

Explain the law of superposition.

In undisturbed rock layers, the oldest ones are at the bottom and the younger ones at the top.
