Do carbon dioxide and methane affect energy ENTERING or EXITING the earth's system?
PLEASE HELP

Answers

Answer:

I believe the answer would be it affects energy exiting the Earth's system.

Explanation:

Carbon dioxide and methane affect energy exiting the earth's system.

What impact does methane have on Earth's atmosphere?

Over the first 20 years after it enters the atmosphere, methane has a warming effect that is more than 80 times greater than that of carbon dioxide. Methane sets the pace for warming in the short term, despite the longer-lasting impact of CO2. Methane produced by human activity is at least 25% of the cause of current global warming.

By absorbing the thermal infrared energy (heat) emitted by the surface, carbon dioxide throws the Earth's energy budget out of balance. Other gases, including water vapor, do not absorb thermal infrared light with wavelengths in that region of the energy spectrum.

Therefore, it can be concluded that Methane and carbon dioxide have an impact on the energy leaving the earth's system.

Can local election results predict national election results

Answers

Answer:No

Explanation: Many States tend to lean twoards a certain party due to factors of location, economy, and religion. For instance, less populated states tend to be more Republican due to little diversity, farming, and Christian values. There are also swing states that change from year to year, so it could be blue one year, and red the next. Taking results from one state is not an accurate prediction, because one state does not reflect the results of all other states.

_____9. Underground water-bearing layers of porous rock, sand or gravel
_____10. To remove the salt from ocean water or groundwater

Answers

Answer:

Explanation:

5. The earth’s surface from the edge of the continent to the deep of the ocean

Continental shelf

The continental shelf is a part of the seafloor. This is closest portion of the seafloor to the land.

6. The rock portion of the earth’s surface

lithosphere

The lithosphere is made up of the crust and upper part of the mantle. Most of the rocks on earth are found in the lithosphere. Below the lithosphere is the asthenosphere

7. The part of the earth where plants and animals live

biosphere

The region of earth where all life forms can be found is the biosphere.

8. A fracture in the earth’s crust

Faults

A fault is a fracture within the earth's crust. It is formed as a result of brittle deformation of the earth.

9. Underground water-bearing layers of porous rock, sand or gravel

Aquifer

An aquifer is a porous and permeable formation within the earth that bears ground water.

10. To remove the salt from ocean water or groundwater

Desalination

In areas where the only source of water is ocean water, desalination is important because the saltiness of the water can be removed by this process.


In picture B, new rocks were introduced. What law is best explained
in this kind of rock stratum?

Answers

Answer:

Principle of cross-cutting relationships

Explanation:

The principle introduced in this rock stratum is the principle of cross-cutting relationships.

This principle states that "in a sequence of rock strata, the feature that cuts another is younger than the rocks they permeate through".

In this we see a sequence of rock strata that has been cross-cut by a fault. The fault is a reverse fault. From the principle of cross cutting relationship, the fault is younger than all of the strata in this sequence.

Since new rocks were introduced in picture B, the law which best explain this kind of rock stratum is: Steno's law of superposition.

Nicolas Steno was a 17th-century Dan-ish geologist who developed the four (4) laws of stratigraphy.

Basically, these laws governing stratigraphy revealed a lot of information to humans about the formation of a rock and its layers. Also, the laws of stratigraphy describes how endogenic and exogenic geological processes give rise to alteration in rocks, thereby, leading to the formation and deformation of rock layers.

The four (4) laws of stratigraphy include the following:

Law of original horizontality.Law of cross-cutting relationships.Law of lateral continuity.Law of superposition.

Steno's law of superposition states that within a sequence of rock layers (rock strata) in sedimentary rocks, the oldest (first) strata lies at the base (bottom) of the sequence while younger (newer) strata sit atop the older strata.

Hence, the sequence of rock layers (rock strata) in sedimentary rocks typically marks the time of deposition of each of the rock layers according to Steno's law of superposition.

In conclusion, the introduction of new rocks in picture B best explains Steno's law of superposition.

A dairy decides to cut back on the production of chocolate-flavored milk and to increase its production of strawberry-flavored milk. How does this decision affect the supply curve for strawberry-flavored milk?

Answers

Answer:

The supply curve for strawberry-flavored milk will go up.

Explanation:

When the company has decided to cut down on the production of chocolate-flavored milk and increase the production of strawberry-flavored milk it certainly had its own reasons. The primary reason for such a move was most probably changes in demand, with the demand for chocolate-flavored milk going down, while the demand for strawberry-flavored milk going up.

With the increased production of strawberry-flavored milk, the supply curve for it will experience changes, manifested through rising, or rather the curve will move up. There can be several reasons as to why the demand for this type of milk has increased, but the two most probable ones are different preferences in taste among newer and emerging clientele, and maybe an emerging trend in the society.

Answer:

The supply curve for strawberry-flavored milk will go up.
