B.
Explanation:
Child labor is important to Brazil's economy and to individual families.
BraziL's GDP per capita is estimated to be around $23,000.
The global carbon dioxide levels increase the temperature when higher, and lower the temperature when lower.
Explanation:
The carbon dioxide is the most abundant and most important greenhouse gas. This gas has the property to trap and keep heat, thus instead of the heat going back into space, it is retained in the atmosphere. To put is simple, the more abundant the carbon dioxide is in the atmosphere, the higher the temperatures are, the lower the levels of the carbon dioxide, the lower the temperatures.
In recent times, the global carbon dioxide levels are experiencing an increase. While this is mostly due to the natural processes, the humans have been having bigger and bigger influence because of their activities. With the constant rise of carbon dioxide levels in the atmosphere, the temperatures have been gradually rising, and if the current trends continue it is expected that the global temperatures may rise by several C degrees.
The countries that contribute the most to the carbon dioxide emissions are:

<u>Answer:</u>
All of the above mentioned options can be used by scientists to date the sediment layer they are found in.
<u>Explanation:</u>
- Rock fossils, animal fossils, etc.found in the sediment layer can be used to determine the age of the sediment based on the period of the existence of that animal or the period of formation of the rock.
- Tree rings clearly exhibit the age of the tree. Hence, a sediment layer with the evidence of tree rings can tell the age of the sediment layer.
- An amalgamation of the data obtained from the animal growth rings and the period of existence of that specific animal species can be used to calculate the age of the sediment.
- The intensity of radioactivity left in the isotopes clarifies how old the isotope is.
- The age of mineral elements can be determined exactly with the help of processes like Potassium-Argon dating, Uranium-Lead dating, etc.
- Thus it would be easy to determine the age of the sediment layer containing mineral elements.
