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.
Answer:
The Sahel has a tropical semi-arid climate (Köppen climate classification BSh). The climate is typically hot, sunny, dry and somewhat windy all year long. The Sahel's climate is similar to, but less extreme than, the climate of the Sahara desert located just to the north.
Explanation:
Answer:
B. Geocentric solar system
Explanation:
The scientific community is the one that accepts or dismisses theories. Some theories are accepted, and that is because there are enough evidence that support them, while some theories are dismissed as they have been proven over time that they are not correct.
One of the theories that is outdated and has been dismissed by the scientific community is the theory of the geocentric solar system. This theory has been in place and widely accepted for a very long time, pretty much two millenniums.
This theory was basically suggesting that the Earth is the center of the solar system. The Sun, Moon, all the other planets that were known, as well as the stars, were all orbiting around the Earth. This has been proven as wrong (except that the Moon is orbiting around Earth), and that the theory is far away from the truth, so naturally once there were enough evidence it was dismissed.
Answer:
law of original horizontality
Explanation:
This law of original horizontality posits that all layers of rock must be kept horizontally because they would deform.
Based on the given image, the rocks are already tilted which suggests that nature (or any other source) has started to deform them.
