Answer:
mature
Explanation:
The mature stage of a stream is the second stage of its development. At this stage, the stream had already managed to create its own valley, which is flat and the stream is flooding it occasionally. The surrounding area around the valley though still tends to be higher, and the valley is not very wide, thus having the U-shape. Another characteristic of a mature stream is that it has started to meander. The meandering is at the beginning phase, so it has slight curves which are not moving away a lot sideways.
B. False. It was the French soil.
Answer:
Automobiles release hydrocarbons that react to form pollutants in dry air.
Explanation:
- As carbon from the gasoline mixes with the air it reacts and starts to burn and this burning of hydrocarbon in the air produces heat, smoke, and gases, as well as chemical byproduct like water and carbon particulate matter.
- 22.38% of CO2 is produced by burning one gallon of petroleum. So, for the hydrocarbon to get successfully converted into carbon dioxide and produce carbon monoxide in the air it needs to react and burn, and CO is the result of not a sufficient amount of O2 in the air.
- Various automobiles release the nitrogen sulfur into the air and soil and give sooty dust and particle sizes that can change the composition of the further atmospheric cycle.
- As earth air is composed of <u>78% nitrogen, 21% oxygen, 0.9% argon, and 0.03% carbon dioxide</u>. The more gases that are released more spread the pollutant content of the air.
