The Atlantic Charter, agreed upon by President Franklin D. Roosevelt and Prime Minister Winston Churchill in 1941, outlined their vision for the post-World War II world. Its main message emphasized the principles of self-determination for nations, economic cooperation, and the importance of collective security to prevent future conflicts. It also called for the promotion of free trade and disarmament. Ultimately, the Charter laid the groundwork for the establishment of the United Nations and the post-war international order.

I would choose to be a small fish in an ocean. While being a big fish in a lake may offer immediate recognition and power, the vastness of the ocean provides greater opportunities for growth, learning, and exploration. Being in a diverse environment allows for interactions with a wide range of ideas and experiences, which can lead to personal and professional development. Ultimately, the ocean represents potential and the chance to thrive in a larger context.

Long chains of mountains that rise up from the ocean are known as oceanic ridges. These underwater mountain ranges are formed by tectonic plate movements and volcanic activity, often marking the boundaries between tectonic plates. The Mid-Atlantic Ridge is one of the most well-known examples, where the Eurasian and North American plates are moving apart. These ridges can significantly influence ocean currents and marine ecosystems.

The sea that separates the two largest islands, Greenland and New Guinea, is the Arctic Ocean, which lies to the north of Greenland, and the Coral Sea, which is located to the northeast of New Guinea. However, if considering the largest islands in terms of land area, then the sea separating Greenland from the next largest island, New Guinea, would primarily involve the Pacific Ocean and the surrounding seas.

The phrase "we shall fight on the seas and on the oceans and in the air, and we shall never surrender" was said by Sir Winston Churchill. He delivered this statement during a speech to the House of Commons on June 4, 1940, as part of his efforts to rally British support during World War II. This speech emphasized resilience and determination in the face of adversity.

Saint-Domingue, a French colony in the Caribbean, became the independent nation of Haiti following a successful slave rebellion that began in 1791. This revolution led to the establishment of Haiti as the first black-led republic and the first independent nation in Latin America and the Caribbean in 1804. The struggle for freedom was marked by significant challenges and was a pivotal moment in the history of slavery and colonialism.

Córdoba, located in southern Spain, is approximately 140 kilometers (about 87 miles) from the Mediterranean Sea. The nearest coastal city is Málaga, which is a popular destination along the Mediterranean coast. The journey from Córdoba to the coast typically takes around 1.5 to 2 hours by car.

If you travel past the neritic zone, you reach the oceanic zone, which encompasses deeper ocean waters beyond the continental shelf. This zone is characterized by greater depths, reduced light penetration, and a diverse range of marine life adapted to the open ocean environment. It includes various sub-zones, such as the epipelagic (sunlit), mesopelagic (twilight), and bathypelagic (dark) zones. The oceanic zone plays a crucial role in global climate regulation and marine biodiversity.

At a depth of 40 meters, ocean temperatures can vary significantly depending on the location and time of year. Generally, in temperate regions, the temperature can range from about 5°C to 15°C (41°F to 59°F). In tropical regions, it might be warmer, typically around 20°C to 25°C (68°F to 77°F). However, in polar areas, it can be near freezing.

Animals in the deep ocean have evolved specialized adaptations to withstand high pressure. Many possess flexible bodies made of soft tissues that can compress without damage, while others have unique biochemical adaptations, such as special proteins and enzymes that function optimally under extreme conditions. Additionally, deep-sea creatures often lack air-filled cavities, reducing the risk of collapse under pressure. These adaptations allow them to thrive in one of the most challenging environments on Earth.
