Answer:
A jet stream is a type of air current that forms high in the atmosphere. On average, jet streams move at about 110 miles per hour. But dramatic temperature differences between the warm and cool air masses can cause jet streams to move at much higher speeds — 250 miles per hour or faster.
Explanation:
Jets streams play a key role in determining the weather because they usually separate colder air and warmer air. Jet streams generally push air masses around, moving weather systems to new areas and even causing them to stall if they have moved too far away.

Imagine you are a city planner. You have the option of providing electricity to your city either through natural gas or through nuclear power. Natural gas is slightly cheaper, but new carbon taxes are about to be implemented in your state. Which do you decide to use? Why?
Answer:
Nuclear power
Explanation:
Even though it may cost a little more, it probably has the less effect on the environment. In times like these with climate change and the earth dying, it is important to do the best we can to reduce it. It has cons tho, nuclear power can be extremely dangerous if it goes wrong... Despite its safety measures, it's still pretty dangerous. Hope it helps!
The natural gas is slightly cheaper but as per taxes in the state, but for city planning more effcient way is to use nuclear power. Thus city panning can be done.
What is nuclear power?Nuclear power is a clean and efficient way of making use of energy resources that can be sued for boiling water that runs the turbines that generate electricity.
The nuclear power is power that is obtained from the fission and the nuclear decay. Even though nuclear power costs bit more but its less effect on the environment.

Where do you think chemical weathering of limestone would be faster- in a hot desert or in a rainy northern valley? Please explain and quick!
Answer:
rainy northern valley
Explanation:
in a desert it wont rain much as it is closer to the equator so less chance but the valley is north so higher chance of rainfall in the first place and the things in a rainy northern valley are more susceptible to chemical weathering due to the rocks.
Rock Layer E is 250,000 years old. Rock Layer C is 200,000 years old. Rock layer C has not undergone radioactive decay and has 18 radioactive isotopes. The half-life is 50,000 years. Rock Layer E has undergone radioactive decay ONCE, how many daughter and parent isotopes are present in layer E?
Answer:
Explanation:
By definition, after a radio active decay, a parent isotope will create a daughter isotope.
Layer C is exactly one half-life from Layer E at 50000 years. So half of the original parent isotopes from Layer E would have decayed to form daughter isotopes. As C has 18 radioactive isotopes together, E should have 6 daughter and 6 parent isotopes.
Answer:
Explanation:
Rock Layer E is 250,000 years old. Rock Layer C is 200,000 years old. So the two layers are off by 50,000 years; equal to one half-life.
As Rock Layer E has undergone radioactive decay ONCE, each parent isotope forms one daughter isotope after the decay.
Rock layer C has not undergone radioactive decay and has 18 radioactive isotopes. So that represents an equal number of parent and daughter isotopes, i.e. 9 parent and 9 daughter isotopes.
So there are 9 parent and 0 daughter isotopes in layer E.

Describe two effective means of preventing the spread of malaria.
Answer:
There are two central blocking systems: Protective bed nets treated with long-lasting instinct poison prevent bites from malaria-infected mosquitoes and kill them. Nets should be available for free or at low prices because of high subsidies. There should be one net per two people who are at risk of being infected.
Explanation:
Presently, Mosquito control and mosquito-bite prevention are the two key approaches used to prevent malaria.
How can you prevent the spread of malaria?Personal protection measures against mosquito bites- Malaria is primarily transmitted at night since the majority of Anopheles mosquitoes bite at night. Wearing clothing that covers the majority of the body, using insect repellent on exposed skin, and using mosquito bed nets are all ways to prevent mosquito bites. Age and status affect the kind and strength of repellents.Mosquito prevention- The effectiveness of vector control strategies is dependent on the vector species, the biology of the mosquito, the epidemiological situation, the cost, and the acceptability to the people. The primary current approaches concentrate on reducing human-mosquito interaction and eliminating larvae through environmental management.To learn more about malaria

When a plane lands at the local airport, it touches ground and creates an angle between the ground and the belly of the plane. What is a good estimate of the angle measurement?
Answer:
Approximately 3 degrees
Explanation:
As well as taking off, the landing of the plane must be monitored very well, allowing the entire trip to be made safely and efficiently. At landing, it is important for the pilot to estimate which is the best descent profile and what is the best angle to be established between the ground and the belly of the plane. It is preferable that this angle is approximately 3 degrees, which promotes a safe landing, but this value can have small variations.

Answer:
Mountain ranges, earthquake and formation of new lakes occurs.
Explanation:
When two places comes together forming mountain ranges in that area. When two plates move away from one another, earthquakes occurs and magma rises to the surface.
