D.Georgia to Alabama
Explanation:
There are records of manatee sighting during the summer months in areas such as Alabama, Georgia and South Carolina. They migrate north in the summer months.
The manatees do not withstand temperatures below 21 degrees Celsius.
Most manatees migrate seasonally over long distances between a northern warm season range.
In winter the manatees are concentrated in Florida.
Answer:
C. Cutting down forests.
Explanation:
Carbon dioxide is an inorganic gaseous molecule with the chemical formula, CO2. It is naturally released into the atmosphere via a lot of processes. However, CO2 is the most important greenhouse gas as it contributes the most to the global warming effect of the Earth.
The effects of an increase in CO2 concentration in the atmosphere is as follows:
- increase in water contamination and floods
- ocean acidification
- reduction of cold-related deaths
However, the cutting down of forests is not an effect of an increase in CO2 concentration but rather a cause.
The cycle of heating, rising, cooling and sinking is called a convection current. These currents are caused by the very hot material at the deepest part of the mantle rising, then cooling, sinking again and then heating, rising and repeating the cycle over and over.
That's because glaciers have rocks embedded in them, which cause these striations.
