state Horton's law on drainage basin and evaluate it's application on cartography and map analysis
There are four laws given by Robert. E. Horton : They are, the law of stream numbers, the law of stream lengths, the limits of infiltration capacity, and the runoff-detention-storage relation.
Law of stream numbers:
the number of streams in a given drainage basin which are in different orders tends to be closely equal to inverse geometric series, in which the ratio and the first term are bifurcation ratio and unity respectively.
Law of stream lengths:
The average of the lengths of streams of all the different orders in a drainage basin tends to be approximate to a direct geometric series in which the first term can be written as the average length of streams of the first order.
Limits of infiltration capacity:
It is the upper limit of infiltration rate which includes infiltration and percolation and is written in-depth per time. No surface runoff would occur if the perception rate is less than or equal to the infiltration capacity.
Runoff-detention-storage relation:
In many cases delay of runoff along the storage has merits and the retention and detention facility can determine a large role in stormwater.
Applications:
Horton's law can be useful for cartography or to draw maps and analyze them by calculating the stream orders. As stated it can exhibit geometric relationships. By getting to know the enter and exit of the lengths of the stream.

because of the cool air and the position of the andes mountains located to the east what can you tell me about the strip of land between the coast and the mountains
The cool air and the position of the Andes Mountains located to the East, show that the strip of land between the coast and the Mountains, receives little rainfall because it is on the leeward side of the Andes Mountains.
What is the leeward side of a mountain?The leeward side of a mountain refers to the area that does not receive much rainfall because of the fact that it is in the rain shadow of the mountain. Think of it this way, winds that are warmer and full of moisture, come up the windward side of the mountains and as they ascend, they become colder and eventually fall as rain. When they reach the other side of the mountain (leeward) side, they have very little moisture left and are colder.
This is the case with the strip of land between the Andes Mountains and the coast in South America. As it is in the leeward side, it receives cold air and little rainfall which is why most of this strip of land is a desert that receives less than 0.6 inches of rain per year.

Answer:
To control Earth’s mounting climate emissions, we really have our work cut out for us.
First, greenhouse gas emissions must be reduced to nearly zero by 2050 to prevent massive sea level rise, drought and heat waves. But that isn’t enough, since already-emitted carbon dioxide lingers in the atmosphere for millennia. To meet climate goals, this harmful gas must be removed from the air in a process called “negative emissions,” according to scientists at the virtual Comer Climate Conference this fall.
“There’s no scenario that keeps us under even 2 degrees [Celsius of warming] without negative emissions,” said physicist Raymond Pierrehumbert of the University of Oxford.
That is, no realistic scenario, he added.
“If you wave a magic wand” to erase CO2 emissions, that would prevent catastrophic warming, Pierrehumbert said in an email.
Though there’s no magic wand, the Earth does have a few defenses against changing climates. Some natural chemical reactions take carbon dioxide from the atmosphere and store it away. On their own, these methods take many thousands of years, but they would remove CO2 much more quickly if humans could accelerate them.
To succeed, though, the world must dramatically reduce emissions with green energy alternatives such as solar and wind. That way, the negative emissions techniques remove CO2 that’s already accumulated in the atmosphere.
Chemical reactions with rocks
If it weren’t for silicate weathering, Earth would be a hot, almost Venus-like hellscape. Carbon dioxide mixes with rain and causes the weathering, or breakdown, of rocks. This sets in motion chemical reactions that remove CO2 from the atmosphere and store it as minerals hidden away on the ocean floor.
This process has helped control Earth’s temperature throughout history.
“If it gets hotter, the silicate weathering goes faster, and it pulls CO2 out of the atmosphere. And if it cools down, silicate weathering slows down, so CO2 builds up,” said R.J. Graham, a doctoral student at the University of Oxford. “So it sort of acts as a thermostat for Earth’s climate.”
But now, human-forced climate change is warming Earth too quickly for it to be controlled by natural silicate weathering, which can take hundreds of thousands of years to work. To have a larger impact, Graham said we’d have to use enhanced weathering to speed up the process.
Some pieces of green olivine
A silicate rock called olivine is particularly good for removing CO2 through weathering. If people mined olivine, broke it into tiny pieces to increase its surface area and distributed it on land or in the oceans, it would get weathered at high rates and remove lots of CO2.
“[This idea] hasn’t really had as much attention paid to it as I think it deserves,” Graham said.
Enhanced weathering has the potential to lower atmospheric CO2 concentrations — which currently sit at the unsafe level of over 410 ppm — by 30 to 300 ppm by 2100, according to a report in Nature Climate Change.
A nonprofit called Project Vesta, unaffiliated with the Comer conference, hopes to create beaches with the ‘sand’ made of crushed olivine. Ocean waves will weather the rock quickly, and at scale, this could remove a lot of carbon dioxide from the air.
But it’ll take a lot of rock — to neutralize one year of carbon emissions, it takes a cube of olivine 6.34 miles on each side. Though it’s not as much as the coal mined each year, that cube would be taller than Mt. Everest, which is just under 5.5 miles high. And that’s not the only challenge.
“It’s an interesting concept, but it also might be dangerous, because you’re dumping a lot of rocks into the ocean that’ll have a lot of other trace metals and things that might screw with the biology in the oceans,” Graham said. “It’s something that needs to have a lot more research done.”
Silicate weathering does affect the oceans — it ultimately makes them more basic, or alkaline. Making the oceans more alkaline helps take CO2 out of the atmosphere, and other scientists are studying how to make that happen.
The big, blue carbon sink
Earth’s oceans help to slow climate change by absorbing carbon dioxide, but as they do, the water becomes more acidic. If compounds were added to the oceans to make them less acidic and more alkaline, the oceans would pull even more CO2 out of the air.
Some scientists explore ways this process called ocean alkalinity enhancement could remove CO2 from the atmosphere. Sophie Gill, a final-year Ph.D. student at the University of Oxford, wants to know what effect this has on marine life.

Describe how you would use a tool to see the spectrum of a firefly's light. Explain what the spectrum
tells you about the light the firefly gives off. Include : comparison of the wavelengths of the light.
The method that fireflies produce light is comparable to how glowsticks do. We refer to this characteristic as bioluminescence when it takes place within a living thing.
What is the spectrum involved in Fireflies?By providing oxygen to the other chemicals required to make light, a firefly can control the start and stop of the chemical process, and consequently, the start and stop of its light emission. The cause is chemiluminescence, a chemical reaction that results in light.
This occurs in the insect's light organ. When there is oxygen present, the light organ is activated; when there isn't, it is inactive. Since insects lack lungs, they use a complicated network of progressively smaller tubes called tracheoles to carry oxygen from the environment to their internal cells. Given the comparatively slow pace of the muscles that control oxygen transport, it has long been unclear how some firefly species accomplish such a high flash rate.

2. Pretend that the temperature today is 5° C (9° F) higher than yesterday. Now consider an increase of 5° C (9° F) in average global temperature. How are these two scenarios different?
The difference between a daily temperature rise and an average is that averaging means much larger increases over a larger number of days.
How is the daily temperature rise calculated?To calculate the daily temperature increase, the temperature of the previous day must be taken into account. For example, the day before there was a temperature of 10°C, so an increase of 5°C would be when the next day the temperature is 15°C.
How is the average temperature rise calculated?To calculate the average temperature increase, the temperature of several days in a row must be taken into account.

O a. increase; decrease
O b. decrease; increase
Oc. no change; no change
d. decrease; no change
Sinuosity decreases as a meander cutoff forms along a meandering stream. Hence, the correct response to this question will be option (d).
Give a brief account on meander cutoff .A meander cutoff in a river is breached by a flow that joins the two nearest parts of the hook to form a new channel, a full loop, and this is known as a meander cutoff. The river flow progressively abandons the meander due to the greater gradient decrease, which causes the meander to get soiled with deposited sediment. A meandering river's natural progression includes cutoffs.
Due to producing a vortex like in a stirred coffee cup, meandering rivers flow higher and as a result, with more overall flow, pressure, and erosion on the outside of their bends. As a result, the river erodes the outer bank more. A river's inside bend has a lower water level, secondary flow churns sand and gravel across the riverbed to form shallows and point bars, and air friction and bed disturbances work against a greater percentage of the water column since the column is shorter, slowing the water to variable degrees.
