Answer:
Iron oxides appeared after the emergence of cyanobacteria.
Explanation:
The composition of Earth's atmosphere in the first couple of billions of years of its existence was nothing like the atmosphere of today. This had a big influence on the processes that were taking place, or rather what processes and to what extent could have happened in those conditions. One big difference between the atmosphere then and after is the levels of oxygen.
Until the appearance of cyanobacteria, the oxygen levels in Earth's atmosphere were very low, and the same goes for the oceans. With a lack of oxygen, the process of oxidation was absent as well. The cyanobacteria though managed to produce oxygen, and this was on such a high scale that they changed the composition of Earth's atmosphere and the oceans. Not just that this enabled complex lifeforms to develop, but it also enabled the process of oxidation. Iron oxides for example occurred only after cyanobacteria appeared, and this can easily be seen when dating the oldest iron oxides and compare that age with the appearance of cyanobacteria.

WILL AWARD BRAINLIEST PLEASE HELP IMPORTANT HELP IS NEEDED PLEASE PLEASE QUICK!!! Describe how a government might manipulate a map to tell a particular story.
Answer:
A goverment that is authoritarian in some way might change a map to the side of themselves. For example, Kashmir and Jaipur are being fought over by India, Pakistan, and China without actually fighting. In thier own countries, the goverment will change the maps to show that they have conquered these areas to show the public. Or when China manipulates its maps from time to time to show only in its population how some famous mountains are controlled by China or how before conquering Tibet, China already showed its maps to be controlling Tibet at the begining of its communist rule to gain the support of the people.

The ratio of a to b is 3 to 4, and the ratio of c to b is 1 to 2. What is the ratio of a to c?
Answer:
3:2
Explanation:
From the given problem;
a : b = 3 : 4
c : b = 1 : 2
So what is the ratio of a:c
a : b : c = ?
Since
a : b b : c
3 : 4 2 : 1
If we multiply b : c by 2 ;
b : c = 4 : 2
So;
a : b b : c
3 : 4 4 : 2
So;
a : b : c
3 : 4 : 2
So;
a : c = 3:2

Explain brahmaputra river system
Answer: The Brahmaputra river flows in China, Bangladesh, and in India.

When the Himalayan snow melts it causes extensive flooding. Upper course of river is known as Tsangpo. In Arunachal Pradesh this river is called Dihang or Sihang river. The river is used for inland navigation instead for irrigation for agricultural purposes.

Urban Sprawl increases carbon dioxide emissions by
1 - expanding the use of public transportation
2 - increasing the need to drive
3 - generating more factories
Urban Sprawl increases carbon dioxide emissions primarily through increasing the need to drive. Therefore, option (2) is correct.
Urban sprawl occurs when cities expand into suburban or rural areas, resulting in low-density development, longer commutes, and more car use. Vehicle use raises [tex]CO_{2}[/tex] emissions.
As cities expand, distances between homes, businesses, and other destinations grow, making public transit less efficient. This increases private vehicle use for commuting and transportation. Private automobiles emit carbon dioxide by using fossil fuels like petrol.

Define the term remote sensing, and explain whether GPS and GIS are considered examples of remote sensing, and why. (Think about ways in which satellite imagery can be used to track changes on Earth's surface.)
Explanation:
Remote sensing is the process of gathering information about the earth without actually coming into contact with the features on ground. Remotely sensed data are obtained by means of orbiting satellites that are moving round the earth.
Geographic information systems is a broad category that describes the process of gathering, storing, analyzing and presenting geographical data. A remote sensing unit and GPS device are components of the GIS framework. Also, there is a software where the data gathered by a GPS and remote sensing units are interpreted for use. So, GPS and remote sensing are subunits of GIS.Dividing a number by 2 always results in a smaller number.

Which of the following best represents a convergent boundary where an oceanic plate and a continental plate meet?
A The San Andreas Fault.
B. The "Ring of Fire" around the Pacific Ocean.
C. The Himalaya Mountains between India and China.
D. The mid oceanic ridge in the middle of the Atlantic Ocean.
Answer:
B. The "Ring of Fire" around the Pacific Ocean.
Explanation:
The "Ring of Fire" around the Pacific Ocean is the best example of a convergent boundary where an oceanic plate and continental plate meets.
At such margins, subduction is the order of the day. Due to the differences in the density of the plates involved, the oceanic plates goes beneath the continental plate. The pacific sea floor is ocean crust and it is denser. As it slides beneath the continental crust, subduction zones are created. This circular geometry of the subduction zone is known as the pacific ring of fire.The stem growing upright is an example of:
A) Positive Photosynthesis
B) Negative Photosynthesis
C) Positive Geotropism
D) Negative Geotropism
Answer:
D) Negative Geotropism
Explanation:
The stem growing upright is a typical example of negative geotropism.
Geotropism is the growth of a part of plant towards the pull of gravity.
Gravity always pulls down on every object. When a body grows downward, then it is responding to a positive geotropism.When a body begins to grow upward, again gravity, then it is negative geotropism.In this case, the negative geotropism is exhibited by some plant roots.
Also, some tree branches can also grow downward and this shows positive geotropism
The way plant grows is due to some factors that influence its growth. The stem growing upright is an example of negative geotropism
Geotropism is known to be when a plant show forth directional growth due to its response to gravity.The shoot tip often shows negative geotropism when it grows against the force of gravity.
The negative geotropism is simply known also as the ability of plant stems and other parts to grow upwards.
Conclusively, it is regarded as negative geotropism only due to the fact that the plant is growing away from the force of gravity.
