Which of the following describes part of the evolution of an elliptical galaxy?
A)It will turn into an irregular galaxy when it has used up all of its gas and dust.
B)It may result from the collision and merger of spiral galaxies.
C)It evolves from a single spiral galaxy when the spiral has used up all of its gas and dust.
D)It would become a starburst galaxy if it were to move through the hot intergalactic medium of a cluster.

Question

Quizplus · Accepted Answer

Elliptical galaxies can be formed through the collision and merger of spiral galaxies. This process disrupts the spiral structure and results in a more spheroidal shape characteristic of elliptical galaxies. Option A is incorrect as elliptical galaxies do not turn into irregular galaxies when they run out of gas and dust, instead they become what is known as a "red and dead" galaxy. Option C is incorrect as elliptical galaxies do not evolve from a single spiral galaxy, as they have different structures and formation mechanisms. Option D is incorrect as starburst galaxies are characterized by intense star formation, and elliptical galaxies are typically devoid of significant amounts of gas and dust and therefore cannot experience such a burst of star formation.
