Cat 3 (HR/Componts/Plate Boundaries)

Front

What is the HR Diagram?

Back

The Hertzsprung-Russell Diagram (HR Diagram) is a scatter plot of stars showing the relationship between the stars' absolute magnitudes or luminosities versus their stellar classifications or effective temperatures.

Front

What type of star is the Sun classified as?

Back

The Sun is classified as a Main Sequence star.

Front

What is a galaxy?

Back

A galaxy is a massive system that consists of stars, stellar remnants, interstellar gas, dust, and dark matter, bound together by gravity.

Front

What force holds a galaxy in place?

Back

Gravity holds a galaxy in place and gives it its shape.

Front

What is a plate boundary?

Back

A plate boundary is the region where two tectonic plates meet.

Front

What are the three main types of plate boundaries?

Back

The three main types of plate boundaries are convergent, divergent, and transform boundaries.

Front

What happens at a convergent plate boundary?

Back

At a convergent plate boundary, two tectonic plates move toward each other, which can cause one plate to be forced beneath the other, leading to subduction.

Front

What is a divergent plate boundary?

Back

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

Front

What is a transform plate boundary?

Back

A transform plate boundary is where two tectonic plates slide past one another horizontally.

Front

What is a white dwarf?

Back

A white dwarf is a small, dense star that is the remnant of a low or medium mass star after it has exhausted its nuclear fuel.
