Answer:

Nitrogen

Explanation:

I don't know how to explain this

The fraction of oxygen in Earth's atmosphere today is approximately 21%, while it was less than 0.1% around 3 billion years ago.

The fraction of oxygen in Earth's atmosphere today is significantly higher compared to what it was 3 billion years ago. Oxygen levels on Earth have undergone significant changes over geological time due to biological and geological processes.

Around 3 billion years ago, Earth's atmosphere was primarily composed of nitrogen, carbon dioxide, water vapor, and trace amounts of other gases. Oxygen was present in only trace amounts, estimated to be less than 0.1% of the atmosphere.

The increase in oxygen levels occurred as a result of the photosynthetic activity of early cyanobacteria, which released oxygen as a byproduct during photosynthesis. Over millions of years, oxygen levels gradually increased due to the proliferation of these oxygen-producing organisms.

Today, oxygen makes up approximately 21% of Earth's atmosphere. This increase in oxygen has had profound effects on the evolution of life on Earth, allowing for the development of more complex organisms that rely on oxygen for respiration.

In summary, the fraction of oxygen in Earth's atmosphere has significantly increased from less than 0.1% around 3 billion years ago to approximately 21% in the present day, primarily due to the activities of oxygen-producing organisms.

Paleontology.

Explanation:

Paleontology comes under the rubric of the study of Earth sciences. Paleontology is that subspeciality that studies the ancient environments of Earth. Paleontologists studies the history of earth by studying the fossils, that is the remains of plants, animals, bacteria, etc.

These fossils are usually buried under rocks. This science of study lies somewhere between geology and  biology. It studies how humans evlved as species.

An example of paleontology study is the study of Neanderthals, an extinct species of early humans.

Pesticides have permitted agricultural production to expand without an increase in farmland. However, the leaching of pesticides from fields into local water tables, lakes, and streams might have harmful environmental and health implications.

To minimize leaching, environmental protection laws demand that pesticides have a half-life of less than 250 days.A half-life refers to the time it takes for a compound to decompose into half its original quantity. If it takes more than 250 days, the chemical will linger in the environment for an extended period of time. In this scenario, if you have a pesticide sample with a concentration of 0.2M/L from a local farmer and you measure the concentration to be 0.19M/L 25 days later, it is essential to know if the pesticide is in compliance with the regulation.

To check if the pesticide is in compliance with the regulation, calculate the half-life of the pesticide. Then use the half-life to determine if the pesticide is in compliance with the 250-day requirement.Let’s calculate the half-life of the pesticide: t½ = (25 days)/[ln(0.2 M/L)/ln(0.19 M/L)]t½ ≈ 130.9 daysSince the half-life of the pesticide is less than 250 days, the pesticide is in compliance with the regulation. Thus, the pesticide can be used.

Given that the regulatory requirement is 250 days, the half-life of the pesticide is less than 250 days, hence, the pesticide is in compliance with the regulation.

To determine if the pesticide is in compliance with the regulation, calculate the pesticide half-life.

The half-life of a pesticide is the amount of time it takes for half of the initial concentration to degrade.

Mathematically,

\(t1/2 = (ln 2) / k\)

where k is the rate constant for degradation.

Assuming first-order kinetics for pesticide degradation, the concentration of the pesticide at any time (t) can be described by the following equation

C = Co * e^(-kt)

where

Co is the initial concentration and

C is the concentration

t is time

k = (ln Co - ln C) / t

Substitute the given values

k = (ln 0.2 - ln 0.19) / 25 days

k = 0.0122 days^-1

Now we can calculate the half-life:

t1/2 = (ln 2) / k

t1/2 = (ln 2) / 0.0122 days^-1

t1/2 = 56.8 days

Since the half-life of the pesticide is less than the regulatory requirement of 250 days, the pesticide is in compliance with the regulation.

Option A, According to the Mount Pinatubo particulate model, the fine debris and sulfur dioxide that was first released into the atmosphere moved from East to West.

One of the biggest volcanic explosions of the 20th century was the Mount Pinatubo outburst in 1991. The explosion significantly altered the climate of the entire planet by releasing millions of tons of ash and sulfur dioxide into the sky.

According to the eruption's particle model, the easterly trade winds were what caused the erupted material's original atmospheric movement, which was from east to west. The material was ultimately spread to higher altitudes by the dominant westerlies, which led to a drop in world temps and a rise in atmospheric aerosols. One of the most important events in history was the explosion of Mount Pinatubo.

Generally speaking, maritime locations have mild summers and mild winters when compared to continental locations at the same latitude.

Maritime climates are influenced by the ocean, resulting in milder weather conditions. Continental climates, on the other hand, are influenced by land, which leads to more extreme weather conditions. The degree of contrast is determined by the location's proximity to water bodies and the ocean's effects. Maritime locations have moderate temperatures throughout the year, whereas continental locations have more significant fluctuations in temperature and humidity throughout the year.

Maritime locations have mild summers and mild winters when compared to continental locations at the same latitude. This is due to the ocean's regulating influence on the climate. In the summer, the ocean absorbs heat from the sun, preventing the air from becoming too hot. In the winter, the ocean releases heat, which keeps the air from becoming too cold. This is known as maritime moderation.

The city of Donetsk is currently an epicenter of fighting in eastern Ukraine.

The city is situated in the combat zone that has existed in eastern Ukraine since 2014. The Ukrainian Revolution of 2014 and the Russian Federation's subsequent annexation of Crimea set off the conflict, also known as the War in Donbass. Pro-Russian rebels have been battling the Ukrainian government for control of the Donetsk and Luhansk areas of eastern Ukraine. The conflict has gone on for a long time despite multiple cease-fires and peace accords.

When pro-Russian rebels launched an armed uprising against the Ukrainian government in April 2014, warfare in eastern Ukraine broke out. Over 13,000 people have died in the violence, more than 1.5 million people have been displaced, and the area is on the verge of a humanitarian catastrophe. The cities of Donetsk and Luhansk, both of which are found in eastern Ukraine's Donetsk Oblast, have seen a concentration of conflict in particular. Both parties of the ongoing fighting accuse one another of breaking the ceasefire agreement.

The warmest global temperatures since the last ice age occurred in the Holocene Maximum. Thus, option D is correct.

An ice age is a protracted period of cooling of the Earth's surface and atmosphere that results in the presence or extension of continental and polar ice sheets and alpine glaciers. The climate of the Earth varies between ice ages and greenhouse times, when there are no glaciers on the globe.

The most recent ice age peaked around 20,000 years ago, when global temperatures were likely around 10 degrees Fahrenheit (5 degrees Celsius) lower than they are now.

One of the hottest periods occurred between 600 and 800 million years ago, during the Holocene geologic epoch. Temperatures were also regularly high between 500 million and 250 million years ago.

The Holocene Maximum saw the highest global temperatures since the previous ice age. As a result, option D is correct.
