What is a blue shift?

Back

A blue shift occurs when an object moves towards an observer, causing the wavelengths of light to decrease, making the light appear bluer.

Front

What does the Law of Superposition state?

Back

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

Front

What is the Ring of Fire?

Back

The Ring of Fire is a major area in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur.

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 sea-floor spreading.

Front

What is a seismograph?

Back

A seismograph is an instrument that measures and records the details of earthquakes, such as force and duration.

Front

What is the relationship between plate boundaries and volcanoes?

Back

Most volcanic zones on Earth are located near tectonic plate boundaries.

Front

What is a fossil?

Back

A fossil is the preserved remains or traces of a once-living organism, often found in sedimentary rock.

Front

What is the significance of the Atlantic Ocean's sea-floor spreading?

Back

Sea-floor spreading causes continents to move apart, contributing to the theory of plate tectonics.

Front

What is a convergent boundary?

Back

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

Front

What is a transform boundary?

Back

A transform boundary is a tectonic plate boundary where two plates slide past each other horizontally.
