There are 7 continents on Earth. Continents are large landmasses that are separated by water bodies. The 7 continents are Africa, Antarctica, Asia, Europe, North America, Australia, and South America. Each continent has its own unique geography, climate, and diverse ecosystems.

Benjamin Harrison was the 23rd president of the United States. He served from 1889 to 1893. Harrison was a Republican and his presidency was marked by economic prosperity and the passage of several important laws, including the Sherman Antitrust Act. He also oversaw the expansion of the Navy and signed legislation that admitted six western states into the Union. Despite these accomplishments, Harrison's presidency was overshadowed by the economic downturn of the Panic of 1893, which led to his defeat in the 1892 election.

NASA was founded in 1958. This can be verified by historical records and official documents. The year 1958 is significant because it marks the establishment of the National Aeronautics and Space Administration (NASA) as a response to the Soviet Union's successful launch of the satellite Sputnik. NASA was created with the goal of leading the United States' civilian space exploration and research efforts, and it has since become a prominent organization in the field of space exploration and technology development.

Neil Armstrong became the first person to walk on the Moon on July 20, 1969, during NASA's Apollo 11 mission. As commander of the mission, Armstrong piloted the Lunar Module "Eagle" to a successful landing. His iconic statement, "That's one small step for man, one giant leap for mankind," captured the significance of this achievement in human history. Armstrong's historic step marked a pivotal moment in space exploration, symbolizing scientific progress and global unity during the Cold War. Along with fellow astronaut Buzz Aldrin, Armstrong spent over two hours exploring the lunar surface, conducting experiments, and collecting samples.

George Washington was unanimously elected as the first President of the United States in 1789. Known as the "Father of His Country," Washington's leadership during the Revolutionary War and Constitutional Convention solidified his reputation as a unifying figure. His presidency established many precedents, including the two-term tradition and the creation of a Cabinet. Washington's commitment to neutrality in foreign affairs and his Farewell Address are considered foundational for American governance. He declined a third term, emphasizing the importance of democratic transitions. Washington's integrity, vision, and dedication to the nation's founding principles remain iconic in U.S. history.

Spinach is a rich source of iron, a vital mineral crucial for producing hemoglobin in red blood cells. Hemoglobin enables oxygen transportation throughout the body, supporting energy production and cellular function. Iron also plays a role in maintaining a robust immune system and brain development. Spinach contains non-heme iron, which is better absorbed when consumed with Vitamin C-rich foods like oranges or tomatoes. This leafy green is especially beneficial for individuals prone to anemia or iron deficiency. Its high nutrient density, including other vitamins and antioxidants, makes spinach a superfood for overall health and well-being.

The platypus, a monotreme, is one of the only mammals that lay eggs. Found in Australia, this unique creature defies traditional mammalian traits. After laying eggs, the female incubates them by curling around her clutch. Once hatched, the young are fed milk secreted through the mother's skin, as the platypus lacks nipples. Its other distinctive features include a duck-like bill, webbed feet, and a beaver-like tail. The platypus also has electroreceptors in its bill to detect prey in murky waters. This fascinating combination of traits makes the platypus a biological marvel in the animal kingdom.

The Titanic, deemed "unsinkable," tragically sank on April 15, 1912, after colliding with an iceberg during its maiden voyage from Southampton to New York City. The ship's design included watertight compartments, but the iceberg caused extensive damage, leading to flooding. With over 2,200 passengers and crew onboard, insufficient lifeboats contributed to a devastating loss of life, with more than 1,500 fatalities. The disaster prompted major changes in maritime safety regulations, including lifeboat requirements and international ice patrols. The Titanic remains a powerful symbol of human ambition, hubris, and the need for preparedness.

Multiplying any number by zero always yields zero. This principle is fundamental in arithmetic and mathematics. Zero signifies the absence of quantity, and multiplying by zero eliminates all value, regardless of the number. This concept aligns with the distributive property of multiplication, where the sum of zero across multiple terms results in zero. For example, 5 × 0 = 0 because adding zero five times still equals zero. This property is crucial in algebra and calculus, underpinning more complex equations and calculations. Its simplicity and consistency make it a cornerstone of mathematical logic.

. Understanding this helps in distinguishing numerical values, such as thousands (three zeroes), millions (six zeroes), and billions (nine zeroes). This concept is vital for financial calculations, population statistics, and scientific notation, where large numbers are commonly used. Recognizing the number of zeroes in a million aids in comprehending orders of magnitude and the scaling of figures in both academic and practical contexts.
