A depression in the ground due to a cave collapse or acidic water dissolution of limestone is called a B)sinkhole. The collapse has usually happened on the surface layer of the ground. There are many notable examples of sinkholes which can be found around the world, which have become touristic sites. Sinkholes can be caused because of both natural and artificial processes.
Answer:
1. disk
2.halo
3. globular cluster
4.spiral arm
5. spiral galaxy
6. bulge
Explanation:
1. In Spiral or Lenticular galaxies, the galactic disk is the flat portion that consists of 2 components; the stellar component and the gaseous component. The stellar component consists of the galaxy stars while the gaseous component consists of cool gas and dust.
2. The galactic halo is the first portion of the galaxy to be formed. Formation of halos is caused by increased gravitational effects and the presence of primordial black holes. When baryonic and dark matter merges, halos are formed.
3. A globular cluster is a large compact spherical star cluster, typically of old stars in the outer regions of a galaxy.
4. Spiral arms are region of a large concentration of stars in a spiral galaxy. This large concentration of stars are usually very bright and easily noticeable.
5. The Milky Way galaxy consists of flat, rotating disk containing stars, gas and dust, and a central concentration of stars known as the bulge. The spiral arm that I explained above extends from the center of spiral galaxies. This extension makes it resemble a spiral and thus give spiral galaxies their name.
6. The bulge is a large concentration of stars.
Answer:
∎ Like stars, planets are made of gas and dust. ∎ They both have very hot cores. ∎ You can see both planets and stars in the night sky.
Explanation:
It would have been much easier for brainly users to give you the right answer which will coicide with the options that were given with the task if you had attachd some options to choose the correct one. Anyway, I have one statement that will definitely help you with this task : <span>The military leadership felt the country was stable enough, so they permitted democratic elections to take place. </span>
Answer: converge boundary means tectonic plates collide, and one plate slides under the other, causing subduction. divergent boundary means tectonic plates are moving away from each other.
