Quarter2 Review for Comp2

Front

What is the process that leads to the formation of mountains when two continental plates collide?

Back

The process is called orogeny, which occurs at a convergent boundary.

Front

What is an independent variable in an experiment?

Back

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

Front

What is an Astronomical Unit (AU)?

Back

An Astronomical Unit (AU) is the average distance from the Earth to the Sun, approximately 93 million miles or 150 million kilometers.

Front

Which electromagnetic wave has the highest energy and shortest wavelength?

Back

Gamma rays have the highest energy and shortest wavelength of all electromagnetic waves.

Front

What is compaction in geology?

Back

Compaction is the process that occurs when sediments are deeply buried and placed under pressure due to the weight of overlying layers.

Front

What is a convergent boundary?

Back

A convergent boundary is a tectonic plate boundary where two plates collide, often forming mountains or causing earthquakes.

Front

What is the difference between independent and dependent variables?

Back

The independent variable is manipulated in an experiment, while the dependent variable is measured to see how it responds to changes in the independent variable.

Front

What are the three main types of rocks?

Back

The three main types of rocks are igneous, sedimentary, and metamorphic.

Front

What is the significance of the distance from the sun to the earth?

Back

This distance, known as an Astronomical Unit (AU), is used as a standard measurement in astronomy.

Front

What is lithification?

Back

Lithification is the process through which sediments compact under pressure, expel fluids, and gradually become solid rock.
