Answer:
Forms of carbon differ in the oceans.
Explanation:
Two different primary types of carbon exist in the oceans.
- Carbonates - organisms in the ocean absorb carbon dioxide and produce carbonates CO₃²⁻. Calcium and magnesium ions combine with carbonates to form <u>calcium carbonate</u> that make up the bulk of corals and seashells plus <u>magnesium carbonate</u>.
When atmospheric CO₂ dissolves directly into the seawater, carbonic acid is produced, that reduces the pH of seawater.
One of the earth's precious diverse ecosystems comprises of coral reefs. Coral reefs' body is made up of calcium carbonate. However, calcium carbonate acts as a buffer. That's why, as pH decreases, the dissolution of calcium carbonate (corals structure and seashells) increases. It results in a massive extinction of coral ecosystem.
Hence, we should not disturb the balance of nature.
C. 6.81x10^-4
It is negative 4 because the 6 is 4 digits away from the first 0.
Scientific notation has one number and then the decimal place so it can not be A or E.
Answer: It's called the station model because it shows the weather measured at a particular weather station, or an area where the weather is measured. It lets meteorologists see a lot of information in a very small space. The symbols and numbers found there are the same across the world and have hardly changed in 75 years.
Explanation: trust me bro.
You need to be direct about what u talking about
I think it is the C one because it depends on the type of construction in the area
