Modern depositional rates of carbonate sediment in the Caribbean Sea are 1.55cm/1,000yrs. Given this rate, how long would it tak
11Alexandr11 [23.1K]

Answer:

In order to deposit 100 meters of limestone layer, it will take 6,451,600 years

Explanation:

Given that,

The rate of deposition carbonate sediments is 1.55 cm in 1,000 years

⇒ 1.55 cm = 1,000 years

⇒ 1 cm = \frac{1000}{1.55}

⇒ 1 cm = 645.16 years

∵ 1 m = 100 cm

∴ 100 m = 100 × 100 cm

⇒ 100 m = 10,000 cm

So, the time it will take for carbonate to deposit 100 m thick layer of limestone will be-

⇒ 10,000 cm (100 meter) =  645.16 × 10,000 years

⇒ 100 meters = 6,451,600 years

Question 18 (1 point)
Setler [38]

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!

What economic ties did Haiti have to the United States at the time?
VashaNatasha [74]

Over the past two hundred years, the United States has played a important role in the economic and political activity of Haiti, its close neighbor to the south. The United States’ refusal to recognize Haiti as a country for sixty years, trade policies, military occupations, and role in Jean-Bertrand Aristide’s removal from Haiti are little known by Americans, but significant for the development, or rather, lack of development in Haiti. https://library.brown.edu/create/modernlatinamerica/chapters/chapter-14-the-united-states-and-latin-america/moments-in-u-s-latin-american-relations/a-history-of-united-states-policy-towards-haiti/

How are the five major climate regions related to the three zones of latitude.
g100num [7]
<span> The three zones of latitude :
i) Tropics till 23º.45 (between ± 23º.45)
ii) Temperate zone between 23º.45 to 66º.55. in both Hemispheres
iii) Polar Caps between 66º.55 to 90º, in both Hemispheres.
There are six major climate regions :
1. Tropical rain forests
2. Tropical grasslands (Savannah)
3. Deserts - China climate (from West to East)
4. Mediterranean climate - Temperate grasslands (Steppes, Prairie, Pampa, Veld, Downs)
5. Temperate rain forests - Taiga (from West to East)
6. Polar Ice caps
The matching is ---
1,2 : i)
3,4,5 : ii)
6 : iii) </span>
