Tides

Help your child understand what causes ocean tides! This worksheet explains high, low, spring, and neap tides with diagrams.

Tide: the periodic rise and fall of the water level in bodies of water like the ocean. Below is an example of high and low tide. Using the above definition and diagram, match the correct definitions of high and low tide. High Tide the state of the tide when at its highest level during a period of rise and fall Low Tide the state of the tide when at its lowest level during a period of rise and fall A tidal bulgeis a place where the ocean level stretches and gets higher as a result. In diagrams, it is often represented as a blue circle around the Earth. Label "High Tide" and "Low Tide" on the Tidal Bulge diagram below. Write "High Tide" and "Low Tide" exactly how it's written within the quotations. Without the quotations. High Tide High Tide Low Tide Low Tide Fill in the blanks to complete the paragraph below. Use the word bank, and type the word exactly as they appear in the word bank.gravitational pull, opposite, 2.2 times, Spring Tide, Neap Tide, moon, sun, high tide, rotates, low tides, once, twice, enhance, greatest high tides, lower than normal high tides Tides are mostly the effect of the gravitational pull between the sun, Earth, and moon. The moon has a pull on the Earth's oceans that is 2.2 times more powerful than the sun. This pull creates a tidal bulge on whatever side of the Earth it is on causing high tide. It also creates a twin bulge on the opposite side of the Earth because the Earth itself is being pulled towards the sun and leaves behind the water (inertia). This creates a high tide there as well. The sun can enhance or diminish the effects of the moon's gravitational pull. When all three are in a straight line, we experience the greatest high tides. We call this Spring Tide. When all three are at a ninety-degree angle (L shaped), we usually experience lower than normal high tides and greater than normal low tides. We call this Neap Tide. Since the Earth rotates, most places experience high tide and low tide twice a day instead of once. Label the diagram correctly. On each moon position in the diagram, there are two labels. The top label is the phase and the bottom label is the tide. Use the word bank below and type each term EXACTLY as it appears below. If terms appear twice in the word bank, it is because they appear twice on the diagram.
