Answer:
The formation of natural diamonds requires very high temperatures and pressures. These conditions occur in limited zones of Earth's mantle about 90 miles (150 kilometers) or more below the surface, where temperatures are at least 2000 degrees Fahrenheit (1050 degrees Celsius) [1].

Answer:
Mass of carbon dioxide = 7.48 g
Explanation:
Given data:
Mass of lithium carbonate = 12.5 g
Mass of carbon dioxide produced = ?
Solution:
Chemical equation:
Li₂CO₃ → Li₂O + CO₂
Number of moles of Li₂CO₃:
Number of moles = mass/ molar mass
Number of moles = 12.5 g /73.89 g/mol
Number of moles = 0.17 mol
Now we will compare the moles of Li₂CO₃ with CO₂.
Li₂CO₃ : CO₂
1 : 1
0.17 : 0.17
Mass of carbon dioxide:
Mass of carbon dioxide = number of moles × molar mass
Mass of carbon dioxide = 0.17 mol × 44 g/mol
Mass of carbon dioxide = 7.48 g
Explanation:
The idea behind using fossils to correlate two land masses was first put into limelight by a British geologist, Williams Smith.
According to the principle of fossil and fauna succession "fossils and fauna succeed one another in a define order".
This implies organisms evolve in predictable manner.
Since we know that certain types of organisms live within a period in time on the earth surface, we expect that such organisms would be fossilized in the geologic record and preserved.
- Identify the fossil record in one part of the land mass. Log the rock types with the corresponding fossils in them.
- On the other side, repeat the same process.
- Look for unconformity surfaces where some part of the stratigraphic records might have been lost.
- If the fossil records on one side corresponds with that on the other other side, it suggests that the land masses must have once been joined together.
- The logic is that when the organism were on the same land mass, they thrived and lived together.
- They became fossilized together till the lands separated.
