The Earth’s water is constantly (35) __________ through a process known as the water cycle. This fundamental system, which has no real beginning or end, describes how water travels on, above, and below the planet's surface. It is the engine for our planet's weather and a vital system for sustaining all life, powered almost entirely by the sun's energy.

We can think of the cycle starting with (36) __________. This occurs when the sun heats water in oceans, lakes, and rivers. The liquid water transforms into a gas called water vapor and rises into (37) __________ atmosphere. Plants also release water vapor into the air through a process called transpiration.

As the water vapor ascends higher, the air temperature drops, causing it to cool. This cooling process makes the vapor change back into tiny liquid water droplets, a stage known as condensation. The water vapor (38) __________ the visible clouds we see in the sky. Ancient observers noted that clouds (39) __________ significantly heavier just before a storm.

When these droplets combine and become too heavy to stay suspended in the air, they fall back to Earth as precipitation. (40) __________, we experience rain, snow, or hail. This water is then collected in rivers, lakes, and oceans. The collection of water on the planet's surface (41) __________ in providing drinking water and supporting ecosystems.

From these collection points, the cycle begins again with evaporation. The continuous journey of water is essential for regulating global temperatures and distributing water resources across the globe. If this critical cycle were to stop, life as we know it (42) __________ on Earth.

In today's hyper-connected world, making friends online is as common as meeting them in the classroom. Whether through multiplayer games, fan forums, or social media apps like Discord and Instagram, teenagers are forming connections with peers from across the country and around the globe. These relationships can be exciting and rewarding, built on shared hobbies and interests. However, the screen that connects us can also hide the truth, making it crucial to understand the difference between a fun online acquaintance and a genuine, trustworthy friend.

The appeal of online friendships is understandable. For some, it feels easier to talk about personal feelings or niche interests without the social pressures of face-to-face interaction. But this anonymity is a double-edged sword. When you can't see someone's body language or meet their real-world friends, you can never be 100% sure of who they are. Their profile picture could be fake, and their life story could be a complete fabrication. It is this uncertainty that makes people vulnerable to deception.

Recognizing warning signs, or 'red flags,' is a critical skill for online safety. A common tactic used by dishonest individuals is to consistently make excuses to avoid a video call or refuse to share recent, candid photos. Their stories might seem inconsistent, or overly dramatic and perfect. A significant red flag is when a new online 'friend' quickly professes intense feelings of friendship or romance. Most importantly, if they start asking for personal favors that involve money, gift cards, or sensitive information like your phone number or passwords, it is a serious cause for alarm. Authorities in major cities, for instance, frequently issue warnings about such scams.

These situations are not just random acts; they are often calculated schemes. Scammers invest time, sometimes weeks or months, to build a foundation of trust. They listen to your problems, offer support, and create an emotional connection. Once this trust is established, they begin to manipulate your feelings of kindness, loyalty, or even loneliness to achieve their goal, which is usually financial. They prey on the human desire for connection, turning a person's goodwill into a tool for their own benefit.

Protecting yourself does not mean you have to abandon the internet. It simply means being smart and cautious. Firstly, never share private information, such as your full name, home address, or the name of your school. Secondly, remain skeptical of any sob stories that end with a request for money. Thirdly, trust your intuition. If a conversation or a person makes you feel uncomfortable, it is okay to end the interaction and block them. Finally, and most importantly, if you are ever unsure or worried about an online relationship, talk to a trusted adult, like a parent or a teacher. The digital world offers amazing opportunities for friendship, but real-world wisdom is your best defense.
