Let's examine each statement one by one:
The hydrological cycle has no beginning or end. (✓) This statement is correct. The hydrological cycle, also known as the water cycle, is continuous and has no specific starting or stopping point. It involves the movement of water in various forms (liquid, vapor, and ice) through the Earth's atmosphere, surface, and underground. This movement includes processes like evaporation, condensation, precipitation, and infiltration.
The water cycle is absolutely a natural phenomenon. (✓) This statement is correct. The water cycle is a natural and essential process that occurs without human intervention. It involves natural forces such as sunlight, gravity, and temperature differences driving the movement of water on Earth.
The Pacific Ocean is bounded on the east by the Americas. (✓) This statement is correct. The Pacific Ocean, the largest and deepest ocean on Earth, is bounded on the east by the continents of North and South America.
On December 26, 2004, an earthquake generated a Tsunami in the Indian Ocean. (✓) This statement is correct. On December 26, 2004, a massive undersea earthquake off the west coast of northern Sumatra triggered a series of devastating tsunamis in the Indian Ocean, affecting multiple countries and causing significant loss of life and property.
Oceans also help in regulating extreme temperatures. (✓) This statement is correct. Oceans play a critical role in regulating the Earth's climate by absorbing, storing, and redistributing heat. They moderate temperatures, helping to prevent extreme variations, and influence weather patterns and climate conditions globally.
All statements provided in the question are correct regarding the hydrological cycle, the water cycle, the Pacific Ocean, the 2004 tsunami, and the temperature regulation by oceans. Each statement reflects foundational knowledge about geography and environmental science. Understanding these concepts is important for studying Earth's systems.
