this model shows a galaxy group called the local group and the galaxies it contains. each glowing dot represents a galaxy. the model shows the relative sizes of, locations of, and distances between galaxies in the local group. the milky way galaxy and its largest neighbor, andromeda, are labeled and their diameters are shown. determine whether each statement is true or false. andromeda is the nearest galaxy to the milky way. the milky way is the largest galaxy in the local group. it would take light 10 years to travel across the local group. most galaxies in the local group are smaller than the milky way.

Answer

Answer:

  1. True
  2. False
  3. False
  4. True

Explanation:

Step1: Check Andromeda - nearest galaxy

Andromeda is the nearest large - scale galaxy to the Milky Way.

Step2: Check Milky Way - largest in Local Group

Andromeda has a diameter of 250,000 light - years and Milky Way 100,000 light - years, so Milky Way is not the largest.

Step3: Check light travel time across Local Group

The Local Group is 10 million light - years across, so it takes light 10 million years to cross, not 10 years.

Step4: Check size comparison of galaxies in Local Group

Most galaxies in the Local Group are smaller dwarf galaxies compared to the relatively large Milky Way.
