Answer:
d) Chemical composition of its outer regions
Explanation:
Spectroscopy is the study of spectral lines, it's an important part of studying the chemistry that goes on in stars and interstellar clouds, spectral lines can give relevant information because every atom or molecule gives off light at a specific frequency, thus, astronomers can look for gas containing a particular atom or molecule by tuning the telescope to one of the gas's characteristic frequencies. Therefore, we can know the chemical composition or a star's outer regions analyzing the spectral lines.
Even though the spectral shape of a blackbody continuum depends on the temperature of the object an there's a relationship between an object’s temperature and the peak of its spectrum, we don't consider this answer as correct because we are not measuring spectral lines but the continuum.
I hope you find this information useful and interesting! Good luck!
Answer:
Felsic magma
Explanation:
Felsic magmas are higher in silica. The higher the amount of silica in the magma, the more viscous it is. Viscosity determines what the magma will do. Most felsic magma will stay deeper in the crust and will cool to form rocks such as granite. If felsic magma rises into a magma chamber, it may be too viscous to move and so it gets stuck. Dissolved gases become trapped by thick magma and the magma chamber begins to build pressure and felsic magmas will erupt explosively.
C is what I believe the correct answer is!(:
The hurricanes have very negative effect in the Central Americana and Caribbean regions.
Explanation:
The hurricanes are some of the most dangerous natural hazards in the world. They form usually in the warm waters between South America and North America, or rather in the Caribbean region. The strong winds and enormous amounts of rainfall have varying effects, depending on the place, and depending on the type of the place that has been hit by them.
The Caribbean and Central American regions are mostly consisted of poor, developing countries. The infrastructure is of bad quality, the organization levels are low, and the warning systems for dangers are often not functional or notify the people too late. This all results in tragedies when stronger hurricanes hit these regions, with the people having no time to escape because they have been notified too late, or not notified at all. The majority of the houses and other infrastructure gets totally destroyed, and the bad organization often lives the people on their own.
The results of this unfortunately are thousands of dead, badly injured, homeless, lack of food, lack of freshwater, and enormous material damage. This can easily be seen in the likes of:
- Dominican Republic
- Haiti
- Belize
- Guatemala
