The global average atmospheric carbon dioxide in 2019 was 409.8 parts per million (ppm for short), with a range of uncertainty of plus or minus 0.1 ppm. Carbon dioxide levels today are higher than at any point in at least the past 800,000 years.The carbon cycle describes the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. Since our planet and its atmosphere form a closed environment, the amount of carbon in this system does not change.

Explanation:
Each liquid falls somewhere along a scale with acid at one end and alkaline at the other. Normally, ocean water is less acidic than fresh water. Unfortunately, as the ocean absorbs more and more carbon dioxide from the atmosphere, it becomes more acidic. Lemon juice is an example of an acidic liquid.
Explanation:
The law of superposition of strata is one of the principles used in assigning rock strata according to their relative ages.
The law states that "in an undisturbed sequence of rock strata, the oldest rock layer is at the bottom and the youngest on top".
- In a sequence of sedimentary rocks that has not been disturbed, the oldest rock layer is at the bottom.
- This is the layer that was first deposited in the basin.
- Subsequent layers were deposited in the basin.
- These layers are younger than the one at the base that was first deposited.
- First deposited, at the bottom is the oldest layer.

Answer:
150mm is 1.50 decimeter
Explanation: There are 10 decimeters in each meter and 1000mm in each meter.
1000/10=100mm in each decimeter
150mm is 150/100=1.50 decimeter
