Have you ever seen water (21) __________ down a drain? A whirlpool is a much larger and more powerful version of this. These fascinating natural events occur in oceans and rivers, where powerful bodies of water are in motion. They are essentially rotating masses of water, formed by the meeting of hydrological forces beneath the surface.

A whirlpool is most commonly created by the interaction of opposing currents. When one current flows in a certain direction and meets another flowing in the opposite way, (22) __________ energy of this collision needs to go somewhere. As a result, the water begins to rotate. This process is similar to how a storm is formed in the atmosphere, but it happens underwater.

This initial rotation creates a vortex, which is a spiraling movement of water around a central point. The water starts (23) __________ faster and faster, pulling everything on the surface towards its center. The depth and power of the vortex depend on the strength of the original currents. Some whirlpools are small and temporary, while others can be incredibly large and persistent.

The force of a large whirlpool is immense. It creates a strong suction effect that pulls down anything floating nearby, from small debris to large boats. If a small boat were to get too close, (24) __________ almost impossible to escape the pull. This is why sailors have always been cautious in areas known for strong currents.

In conclusion, a whirlpool is a force to be reckoned with. It is a powerful demonstration of nature's forces at work. A famous oceanographer once reported that ancient sailors had warned other mariners for centuries about the dangers lurking in certain waters. These natural wonders are beautiful to observe from a distance but must be respected for their potential danger.

Every click, every comment, and every photo you share online leaves a mark, creating what’s known as your digital footprint. This isn't just a temporary trail; it's a permanent record, an ever-growing collection of data about you. From your social media posts to the websites you visit, everything contributes to this digital identity. It's a concept that might seem abstract, but its implications are very real, especially as you navigate the journey from your school years into higher education and professional life. Understanding this footprint is crucial, because the internet, truly, never forgets. [I]

This digital footprint can be more extensive and enduring than many realize. That funny meme you shared, the strong opinion you voiced in a comment section, or even a casual photo from a party – these all become part of your public record. In today's interconnected world, universities and future employers are increasingly looking beyond traditional resumes. They often delve into candidates' online profiles, seeking insights into their character, judgment, and professionalism. [II]

This trend is particularly evident and growing in Vietnam. Leading tech companies, such as FPT and Viettel, are increasingly incorporating social media profile checks into their hiring processes. They aren’t just looking for technical skills; they are assessing a candidate's overall online presence to understand their communication style, values, and how they represent themselves in a public forum. Knowing that prominent local companies are already doing this highlights the immediate relevance of managing your digital identity for your career prospects right here in Vietnam. [III]

For a 14 or 15-year-old, this understanding is incredibly important. The things you post on platforms like Facebook, TikTok, or Instagram today could potentially be seen by the admissions officer at the university you apply to in just a few years, or by the hiring manager for your first serious job. Posts with inappropriate language, controversial opinions, or images depicting risky behavior, even from years ago, can raise red flags. It’s about recognizing that your online persona is an extension of your real-world reputation, and it can significantly influence how others perceive you. [IV]

Therefore, actively managing your digital footprint is not just a good idea; it’s a vital life skill for future success. This means thinking critically before you post, utilizing privacy settings effectively, and regularly reviewing your online content. Cultivating a positive and thoughtful online presence now will serve as an asset, demonstrating maturity and responsibility to future academic institutions and employers. Your online actions today are an investment in your future, shaping the opportunities that will be available to you tomorrow.
