Answer:

  • d. Proto-star at the end of the Hayashi track.
  • c. On the main sequence.
  • a. Red against just before the helium flash
  • b. Horizontal branch
  • e. White dwarf

Explanation:

  • The protostar is a new star that is formed at the end of the Hayashi track and is luminosity temperature relationship of infant stars that are less than M 3. The protostar ends its period and becomes a Tauri star that is extremely luminous.  
  • After which the main sequence of the stars are formed is the next stage in stellar evolution and is dependent on its mass like the sun after this period the star turn red as it has a hydrogen-rich core and it starts to branch out displaying extreme density.
  • The last stage is the white dwarf star as the star has degenerate and left is the exhaust core which is very dense.

satela [25.4K]

Answer:

There are mainly 4 types of volcanoes.

Explanation:

1. Cinder cones: They are a bowl-shaped crater,  build from particle or blobs of congealed lava that is ejected from a single gas vent, as the air is broken into small fragments that are solidified and falls as cinders.

2. Composite volcanoes: stratovolcano or composite cone are those that form a steep-sided, symmetrical cone of large dimensions built around by lavas. Some examples are Mount Shasta in California, Mount Hood in Oregon.

3. Lava domes: There internal structure is defined by bulbous masses of lava, that are too vicious.

4. Shield volcanoes: These are built entirely by fluid lava, and flow p[ours in all directions.

A volcano can change its surrounding weather patterns but not the climate of a place as a climatic zone is composed of stable and static atmosphere like that of poles, tropics, and temperate lands, etc.  

Not all volcanic eruptions can be predicted successfully as they are also triggered by an earthquake and the active or dominant type of volcano can be identified based on its previous eruption patterns.
