Have you ever wondered why ocean tides (29) __________ and fall every day? This amazing natural phenomenon is mainly caused by the gravitational pull of the Moon. As the Earth rotates, the Moon's gravity pulls on the water, creating 'bulges' on the side of the Earth closest to it and on the opposite side. The Sun also has a gravitational effect on our oceans, but it's much weaker because it's so far away.

When the Sun, Moon, and Earth align, their gravitational forces combine to create very high and very low tides. (30) __________, when the Moon and Sun are at right angles to each other relative to the Earth, their forces partially (31) __________ each other out, leading to weaker tides called 'neap tides'. This gravitational dance happens without fail. In fact, if the Moon disappeared, our planet's tides (32) __________ be much smaller and less regular. (33) __________ coastal ecosystem depends on this predictable cycle. Life in tidal pools, for instance, is specially adapted to the changing water levels (34) __________ these areas.

In an age where everyone carries a powerful camera in their pocket, the line between amateur and professional photography has become blurry. The rise of 'mobile photography' as a serious art form, combined with the 'sống ảo' culture popular among Vietnamese youth, means our phone cameras are used more than ever. But can these pocket-sized devices truly compete with the quality of a dedicated professional camera, like a DSLR?

Smartphones offer incredible convenience. They are lightweight and portable, allowing you to capture spontaneous moments anywhere, anytime. The software inside modern phones is also a major advantage. It uses artificial intelligence to automatically adjust settings for the best possible shot, and popular editing apps allow for quick enhancements. This makes it easy for anyone to produce a visually appealing image with minimal effort.

However, professional cameras still hold a significant edge in certain areas. They have much larger sensors, which capture more light and detail, resulting in higher-quality images, especially in low-light conditions. The ability to use different lenses gives photographers immense creative flexibility, from wide landscape shots to detailed portraits. Furthermore, professional cameras offer complete manual control over settings like aperture and shutter speed, which is essential for creative experts.

Ultimately, the quality of a photograph depends more on the photographer than the camera. A person who understands composition, lighting, and storytelling can create a masterpiece with a smartphone. In contrast, even the most expensive professional cameras can produce boring photos if they are in the hands of someone without artistic vision. The best camera is the one you have with you, but the most important tool is your own creativity.
