Answer:
1) The Big Crunch. 2) The Big RIP.
Explanation:
For The Big Crunch is that's where gravity takes. For The Big RIP is where the expansion of the universe just gets faster until galaxies, planets, stars, atoms and space gets ripped apart.
In a time before railroads and highways, the Great Lakes and St. Lawrence River served as the primary transportation system. Many of North America's largest cities were established along the waterway as commerce flourished between their ports. Today, Great Lakes-Seaway shipping is equally important.
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:
The Cenozoic division of the geologic time scale is an era of the phanerozoic eon.
Explanation:
The Phanerozoic Aeon is the eon we live in and was started 542 million years ago. The word Phanerozoic derives from the Greek and means apparent life (zoico) (faneros).
The Phanerozoic Aeon is divided into three ages:
- Cenozoic Era
- Mesozoic Era
- Paleozoic Era
The ages are divided into periods. The Cenozoic Era is divided into the periods:
