which best describes how the atmosphere's co2 content was regulated before the industrial revolution?

Answers

Answer 1

Before the industrial revolution, the atmosphere's CO₂ content was regulated mainly by plants. This is because plants, together with some organisms, absorb carbon dioxide.

Carbon dioxide, with the chemical formula CO₂, is a chemical compound that is made up of molecules that each have one carbon atom that is covalently double bonded to two oxygen atoms. At room temperature, carbon dioxide is found in the gas state.

Carbon dioxide in the air is transparent to visible light, but it absorbs infrared radiation so it acts as a greenhouse gas. Carbon dioxide is soluble in water, and it is found in groundwater, ice caps, lakes and seawater.

Plants, cyanobacteria and algae use energy from sunlight to synthesize carbohydrates from CO₂ and water in a process called photosynthesis.

He sent reports to superiors about camp conditions that was an argument for the prosecution at Henry Wirz’s trial.

The Union was able to hold its own against the Confederate army in the Eastern theater thanks to Antietam, the bloodiest single-day combat in American military history. Additionally, it provided Abraham Lincoln the self-assurance to make the basic Emancipation Proclamation in a strong rather than desperate situation.

The Battle of Fort Sumter began on April 12, 1861, when Confederate General P.G.T. Beauregard bombarded Fort Sumter after President Abraham Lincoln revealed preparations to resupply the fort. The fort was abandoned by Anderson and 86 soldiers on April 13 following a 34-hour exchange of artillery fire. The first battle of Bull Run was important because it demonstrated that the war was ongoing and that the outcome would not be determined by a single engagement.

which 19 th century phrase best describe the overall efforts of the united states to expand westward to the pacific ocean

Answers

Manifest Destiny is a 19th-century expression that best describes the United States' general intentions to expand westward to the Pacific Ocean.

What is manifest destiny?

It became a cultural belief in nineteenth-century America that American settlers were destined to spread across North America.Historians have stressed that the "appear future" was continually challenged; many supported the idea, but the vast majority of Whigs and other eminent Americans opposed it."American imperialism did no longer constitute an American consensus; it created bitter debate in the countrywide politics at the same time as the Whigs recognized America's ethical mission as one in all democratic instance as opposed to conquering," argues historian Daniel Walker Howe.The phrase was used by then-Democrats to explain the Mexican-American War in the 1840s, and it became heavily used to settle the Oregon boundary dispute. According to historian Frederick Merk, appear future has always dragged ahead because to internal impediments and the problem of slavery, and has never established a national precedent of the United States.

Answers

Answer: The government took a number of steps to ensure that Americans supported the war effort. Congress passed several laws, including the Trading with the Enemy Act, the Espionage Act, the Sedition Act, and the Alien Act, all intended to criminalize dissent against the war. The government also encouraged private citizens to identify and report potential disloyalty among their neighbors, teachers, and others, including those who spoke out against the war and the draft for religious reasons. Wilson believed these steps were necessary to prevent divided loyalties, given the many recent immigrants living in the United States who maintained ties to European nations on both sides of the conflict.
