  • 2. are rare in central regions of galaxy clusters    ---   spiral galaxies.
  • 3. contain many bright, hot stars    ---  Spiral galaxies.
  • 4. are more reddish in color   ---     Elliptical galaxies.
  • 5. contain primarily old, low-mass stars    ---  Elliptical galaxies.
  • 6. contain abundant clouds of cool gas and dust    ---  Spiral galaxies.
  • 7. have significant, ongoing star formation    ---   Spiral galaxies

Explanation:

  • Most galaxies that contain a central bulge that is surrounded by a rotating disk of arms that circles the galaxies are said to be a spiral galaxy.
  • About 60% of the galaxies are made up of spiral shapes and they are mostly found n low-density regions and are in the central of the galaxy clusters. Spiral galaxies often have beautifully shaped made form hot and young stars.

Explain all the types of erosion caused by water
noname [10]

Answer:

There are three types of soil erosion caused by water. They are: Sheet, Rill and Gully.

Sheet Erosion

This type of erosion takes away the top soil over a wide area thereby making it look as though it took a sheet of the top soil. As a result, this is not easy to notice at first glance because the soil from the whole area is gone so there is nothing to compare it to.

Rill Erosion

When water goes in channels and makes lines in the soil a by carrying off the soil that was previously on those lines, that is rill erosion. These channels must be shallow to be considered Rill erosion however because if they are too big, it would become gully erosion.

Gully Erosion

Gully erosion is much like Rill erosion but on a much larger scale. With gully erosion, the channels are much bigger and allow for more soil to be taken. Gully erosion can remove a lot of soil from an area. The Grand Canyon for instance was formed by Gully erosion.

What causes the change of seasons
Klio2033 [76]
The four seasons happen because of the tilt of the earth axis. During different times of the year, the rays of the sun hit different parts of the earth more directly. The angle of the earth's tilts the northern hemisphere towards the sun during summer season while the southern hemisphere is tilted away causing winter. Without the tilt of earth, there would be no seasons. Regions along the equator would be always be warm and sunny while those in the southern and northern hemisphere would be stuck in a gradual gradient of cold and hot.
