Answer:
Parallax would be most effective in measuring distances to stars which are close to the Earth.
Explanation:
In the experiment,
- The parallax shift would decrease as the pencil would move further away from the scientist's eye, so option 1 would be invalid.
- the size of the pencil remains constant, so option 2 would be invalid.
- the parallax shift can be observed when the pencil has objects in the background to provide relation, that is to say, the shift of the pencil when seen relative to background objects; therefore, if we assume that the pencil is a star nearby to the Earth, and the background objects are stars that are further away, then the shift of, and thus, distance to the nearby star can be easily observed.
Answer:
The best answer to the question: The greenhouse effect is driven by the fact that greenhouse gases are:___, would be: Good absorbers of radiation at all wavelengths.
Explanation:
Under normal circumstances, the Earth receives energy from the sun and also produces a bit of its own energy. The energy that arrives from the sun is usually known as shortwave radiation, while the energy that is both absorbed by the Earth´s atmosphere, and the energy produced by Earth itself, becomes part of what is known as the longwave radiation. Greenhouse gases, like water vapor, carbon dioxide and methane trap both longwave and shortwave radiation, which should usually be expelled to a certain extent towards space, and maintain them trapped inside the atmosphere. This bouncing effect between the shield created by the gases and the lower atmosphere, should normally be controlled by the amount of atoms of gases in the higher atmosphere. However, in the greenhouse effect, what is happening is that the amount of gases is too high, and therefore they are trapping most of the radiation, both longwave and shortwave, and keeping it in, allowing the climate to warm up.
Oligarchy: A group of a few people rule a country.
Monarchy: A king or queen rules a country.
Constitutional Monarchy: A king or queen rules the country but has limited powers from a constitution.
Dictatorship: One person is in absolute complete power.
These forms of government are all similar in one way, there is one or a group of people with most of the power. This is unlike other governments which have different bodies of powers that keep each other in checks and balances.
If you are to choose Dictatorship and Oligarchy. Above are two differences.
Similarities are complete control.
Answer:
Stability
Explanation:
Stability (or atmospheric conditions) describes the tendency of the air either with rise and generate storms (destabilization) or resist vertical motion (stability).
As is valid of a balloon, the best way to explain how equilibrium functions is to consider a parcel of air getting a thin , lightweight cover that helps it to stretch but prohibits the air within from interacting with the surrounding atmosphere.
Frankfurt is the capital of Kentucky.
