Earth Science Final Exam Review #1

Front

What is an independent variable in an experiment?

Back

The independent variable is the variable that is changed or controlled in a scientific experiment to test its effects on the dependent variable.

Front

What is a divergent boundary?

Back

A divergent boundary is a tectonic plate boundary where two plates move away from each other, often resulting in the formation of new crust.

Front

What are the layers of the Earth in order from the outside to the inside?

Back

The correct order of the Earth's layers from the outside going in is: crust, mantle, outer core, inner core.

Front

What are the steps of the Scientific Method?

Back

The steps of the Scientific Method are: Make an observation, Ask a Question, Do Background research, Make a Hypothesis, Conduct an Experiment, Analyze your data, Report your results.

Front

What is a transform boundary?

Back

A transform boundary is a tectonic plate boundary where two plates slide past each other in opposite directions.

Front

Define dependent variable.

Back

The dependent variable is the variable that is measured and affected in an experiment, responding to changes in the independent variable.

Front

What is a convergent boundary?

Back

A convergent boundary is a tectonic plate boundary where two plates move towards each other, often resulting in one plate being forced below another.

Front

What is the purpose of a control group in an experiment?

Back

The control group is used as a standard for comparison in an experiment, helping to isolate the effects of the independent variable.

Front

What is the mantle?

Back

The mantle is the thick layer of the Earth located between the crust and the outer core, composed of semi-solid rock that flows slowly.

Front

What is the outer core?

Back

The outer core is the liquid layer of the Earth's core, located beneath the mantle and above the inner core, composed mainly of iron and nickel.
