It is called the compound microscope.
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:
A. On moving water
Explanation:
The canoeing is a sport that is practiced both on moving and calmer waters. The canoeing on the fast waters though seems to be preferred as it is more attractive and more extreme. Unfortunately, those type of waters are very unsafe, as they are quick, there a lot of turns, they are a bigger angle, and there's lot of rocks usually. All of these things are responsible for lot of accidents, and there are lot of people that end up injured or even end up dead.
The Sun is lowest in the sky with less radiation in the Northern Hemisphere during the winter solstice.
Explanation:
The Earth is not static, but instead it is involved in several different motions. One of those motions is the Earth's tilt. Basically, the Earth is tilted with one of its hemispheres (northern or southern) toward the Sun in half of the year, and then in the other half of the year it is tilted with the other hemisphere toward the Sun.
When one of the hemispheres, lets say the Northern Hemisphere, is tilted away from the sky, and that reaches the maximum, it receives the least solar radiation, and the Sun is the lowest on the sky. That occurs on 21 or 22 December, and it is known as the winter solstice. This date represents the start of the winter for the Northern Hemisphere, thus its coldest period of the year.
The four stages on Earth caused by the tilting are:
- spring equinox
- summer solstice
- autumn equinox
- winter solstice
