Answer: Carbon
Explanation:Carbon is the element released by volcanic outgassing,animal respiration and flatulence,burning of fossil fuels and the metamorphism of limestone.
Volcanic outgassing is the release of carbon into the atmosphere mainly in the form of carbon monoxide.
Animal respiration and flatulence are process taking place in animals which leads to the release of carbon dioxide.
Burning of fossil fuels is the use of heat to breakdown fossil fuels such as petroleum leading to the release of Carbon.
Limestone metamorphism is the breakdown of limestone which leads to the release of Carbon to the atmosphere.

Answer:
(4, 3)
Explanation:
<u>Short answer</u>: when the coordinates are on horizontal and vertical lines, as these are, each coordinate value is used twice. Already, x=0 is used twice, as is y=0, so the missing coordinate is x=4, y=3.
The fourth vertex is (4, 3).
_____
<u>Longer answer</u>: The midpoints of the diagonals are the same point, so for rectangle ABCD, we have ...
(A+C)/2 = (B+D)/2
Solving for D, we find ...
D = A +C -B
In clockwise order, the points given are ...
A = (4, 0), B = (0, 0), C = (0, 3)
so we have ...
D = (4, 0) +(0, 3) -(0, 0) = (4+0-0, 0+3-0)
D = (4, 3) . . . . the coordinates of the fourth vertex.
