The Moon and Earth exert a gravitational pull on each other. On Earth, the Moon’s gravitational pull causes the oceans to bulge out on both the side closest to the Moon and the side farthest from the Moon. These bulges create high tides. The low points are where low tides occur. When the sun, moon and Earth are all lined up, the sun’s tidal force works with the moon’s tidal force. The combined pull can cause the highest and lowest tides, called spring tides. Spring tides happen whenever there is a new moon or a full moon and have nothing to do with the season of spring. (The term comes from the German word springen, which means “to jump.”) People can be very active in the low-tide zone. Simple nets can catch fish here, and fishers can collect animals like crabs, mussels, and clams. “The tide is out, our table is set,” is a traditional saying among the Tlingit nation ( tribe), who live along the Pacific Northwest coast in Alaska and Canada.

Twice each month, the moon lines up with the Earth and sun. These are called the new moon and the full moon. When the moon is between the Earth and the sun, it is in the sun’s shadow and appears dark. This is the new moon. When the Earth is between the sun and moon, the moon reflects sunlight. This is the full moon.

The moon’s tidal force has a much greater effect on the surface of the ocean, of course. Water is liquid and can respond to gravity more dramatically.

Perhaps most importantly, engineers can analyze changing tides to better plan for future sea level rise. One recent study looked at the low-lying Pearl River Delta in southern China, which is home to more than 60 million people. Michela De Dominicis, an oceanographer at the National Oceanography Centre in Liverpool, UK, and her colleagues calculated how much tidal ranges would shift for a variety of future scenarios of sea level rise.

If sea level were to rise between 0.5 and 2.1 meters (1.6 and 6.9 feet) in the delta, then cities in its upstream reaches would see tidal increases between 0.1 and 0.5 meters (0.3 and 1.6 feet), the scientists reported in February in Geophysical Research Letters. Add those numbers together and it looks as if water levels could go up between 0.6 and 2.6 meters (2 and 8.5 feet).

If sea level were to rise between 0.5m and 2.1m (1.6-6.9ft) in the delta, then cities in its upstream reaches would see tidal increases between 0.1m and 0.5m (0.3ft and 1.6ft), the scientists found. Add those numbers together and it looks as if water levels could go up between 0.6m and 2.6m (2-8.5ft). The moon’s ability to raise tides on the Earth is an example of a tidal force. The moon exerts a tidal force on the whole planet. This has little effect on Earth’s land surfaces, because they are less flexible. Land surfaces do move, however, up to 55 centimeters (22 inches) a day. These movements are called terrestrial tides. Terrestrial tides can change an object’s precise location. Terrestrial tides are important for radio astronomy and calculating coordinates on a global positioning system (GPS). Volcanologists study terrestrial tides because this movement in the Earth’s crust can sometimes trigger a volcanic eruption. Separated into two parts, the exploration of losing oneself and then the rediscovery in the aftermath of an abusive and toxic relationship. When there is a low tide, the Moon faces the Earth at a right angle to the Sun so the gravitational force of the Moon and Sun work against each other. These tides are referred to as neap tides; a low tide or one that is lower than average. A neap tide happens between two spring tides and occurs twice a month when the first and last quarter Moon appears. Spring tides

Toward the beginning there’s this beautiful passage that so perfectly captures what it’s like to have anxiety. (That’s the bit I saw on tiktok) Heavily recommended just to read for that part. Another tidal energy generator uses a type of dam called a barrage (2). A barrage is a low dam where water can spill over the top or through turbines in the dam. Barrages can be constructed across tidal rivers and estuaries. Turbines inside the barrage can harness the power of tides the same way a dam can harness the power of a river. Barrages are more complex designs than single turbines. As we’ve just seen, the Earth's two tidal bulges are aligned with the positions of the moon and the sun. Over time, the positions of these celestial bodies change relative to the Earth’s equator. The changes in their relative positions have a direct effect on daily tidal heights and tidal current intensity.In the open ocean, the tidal force of the moon will appear as bulges of water facing the moon whereas around land mass the water can spread out onto land creating tides. Types of tides TikTok poet Shelby Leigh presents a moving and inspirational collection of poetry about growing up and embracing all the beauty life has to offer. The perfect gift for fans of Rupi Kaur, Connor Franta, and Cleo Wade. changing with the tides is a powerful collection of poetry that uses the expression of realization as its main theme. the book is unique in its structure with its alteration of letters and poems. there is also a progression of discouragement to empowerment within the voicing. i found many of Shelby's words to be very relatable and they pulled on my heart strings. there are many styles of poetry and prose used throughout. a very lovely collection. i honestly can easily picture many of the poems being used as wall art, phone wallpaper, quotes, and tattoos. they are just that stunning. <3
