After it experiences a "helium flash" a star like the Sun will have a brief period of stability, fusing helium into carbon (and
sometimes oxygen). During this brief stable stage, the star:_________a. Increases tremendously in luminosity.b. Gets to be even larger in diameter than it was as a red giant.c. Returns to the position on the H-R diagram that the star had in its main-sequence stage.d. Is able to fuse many of the heaviest elements (such as iron and gold) in its superhot core.e. None of the answers provided is the correct answer
The helium flash is a thermal nuclear fusion with large quantities of helium gas into carbon. During the red giant phase, the sun is predicted to have a flash 1.2 billion after it leaves the main sequence and this helium fusion cannot be produced by the low mass stars.
The sun in this stage will burn out or run out of its fuel and eventually will lead to gravitational collapse. The star being to shrink in size and core starts to collapse.
1. It can be triggered by tectonic plate movement. - <u>both</u>
2. The name means "harbor wave." - <u>tsunamis</u>
3. It’s movement of land triggered by gravity. - <u> mass wasting</u>
4. Creep and topple are names for two types of this hazard. - <u>mass wasting</u>
5. Scientists use deep ocean assessment and reporting (DART) to warn of this hazard. - <u>tsunamis</u>
6. One example is mud flowing down a hill and onto a highway.
<u>mass wasting</u>
Explanation:
The characteristics of the tsunamis are related to those associated with the shaking of the ground that is produced by the movement of the tectonic plates from below as in the event of the earthquakes and thus the sudden release of the violent energy create huge killer waves and they can also lead to the mass wasting phenomenon.
<u>Hence the process of mass wasting occurs due to the movement of the layers of them is under the flow of the gravity and is a hazard that is associated with the earthquakes.</u>
The major difference between Earth and the other planets in our solar system is that Earth has an atmosphere. The atmosphere is the reason why Earth is livable place.
The presence of mustones by curiosity rover indicates chances of ancient life.
Explanation:
The Yellowknife bay is a geologic formation of the Gale crater on the planet Mars and NASA named the rover as a curiosity. Its primary goal was to assess the potential habitability and whether the mars are capable to support life.
The presence of the mudstones in the geologic depression area on mars leads to its name as Yellowknife i.e the capital of the northwest territory of Canada.
The findings of the mudstone from the stepped bedded stata indicate the clay minerals that show the presence of water and claims that an ancient creator was found on in this region and these indicators of a potential mafic source of origin of deposition.
