Answer:
4. Ultraviolet radiation breaks apart molecules made up of paired oxygen atoms. Individual oxygen atoms bond with paired oxygen molecules to form ozone
Explanation:
Ozone formation in the stratosphere -
The ozone is the stratosphere layer is former naturally by the chemical reaction , with the help of the ultraviolet radiation of the sun and the oxygen molecules .
In the very first step , The UV radiation breaks the oxygen molecule to give two very reactive oxygen atoms .
In the second step , the atoms of oxygen reacts with the oxygen molecules to produce the ozone molecule (O₃) .
And Ozone gas is produced .
Answer:
What does this population pyramid indicate about Denmark's recent population growth?
A. It is relatively stable.
Answer:
Usually famine causes angst between the weakened civilation so the owners of said territories usually hunt for more fertile land so they can sustain their growing population without having being thrown out of power and slain, its often better to satisfy the people who you govern rather than to exterminate to govern the population steadily.
and to own more land is more money and more power for such rulers, if they own more land they can tax more people, and if they own fertile land they can grow crops to sustain themselves, and the people they govern, satisfying the ruler AND the people.
This is true. The best can be seen on examples such as the great depression which led to numerous other issues, while the roaring twenties when everything was calm and sound were also very politically stable for the lives of Americans.
The grassy plains made up the majority of the fertile crescent. Although this region was suitable for farming, it lacked materials like stone, wood, and metal. Knives, spears, weapons, constructing buildings or shelters, and creating fires were only a few of the challenges these shortages brought on for the locals.
Plant and animal cultivation is known as agriculture or farming. Farming of domesticated species produced food surpluses that allowed people to dwell in cities, and this was the crucial innovation in the birth of sedentary human civilization.
Farming has a long history dating back a very long time. Around 11,500 years ago, early farmers started to sow the wild grains they had been harvesting for at least 105,000 years. Domestication of pigs, sheep, and cattle dates back more than 10,000 years. Despite the fact that 2 billion people still relied on subsistence agriculture in the 20th century, industrial agriculture based on massive monocultures began to dominate agricultural production.
