            <h1>Tidal Animation: Earth 🌍 and Moon 🌕</h1>

            <canvas id="tide-animation" width="800" height="400"></canvas>

            <p>

                In this animation, the Earth 🌍 and Moon 🌕 are shown with their relative sizes and distances (not to scale). The Moon's gravitational pull causes the water on Earth's surface to bulge, creating tides on the side facing the Moon and the opposite side. This effect is demonstrated by the blue semi-transparent layer around the Earth.

            </p>

            <p>

                The tides are created due to the gravitational interaction between the Earth and Moon. The Moon's gravity pulls on the Earth, causing the water on the Earth's surface to bulge towards the Moon. This bulge is the high tide. On the opposite side of the Earth, another high tide occurs due to the Earth being pulled towards the Moon, while the water on the far side remains behind.

            </p>

            <p>

                The Earth spins on its axis, making it appear as if the tide is moving around the Earth. In reality, it is the Earth's rotation that causes the tides to change throughout the day.

            </p>

            <p>

                This animation is intended as an educational tool for advanced high school students. It helps to visualize and understand the concept of tides and the gravitational interaction between the Earth and Moon.
