Tides & Seasons

Master tides & seasons! Understand gravity's pull, moon phases, and Earth's tilt. Perfect for 8th-grade science.

Vocabulary Matching Match the term with the best possible definition. High Tide When tides are at their highest elevation Low Tide When tides are at their lowest elevation Spring Tide When tides experience the greatest range between high and low due to the alignment of the Earth, Moon, and Sun Neap Tide When tides experience the least range between high and low due to the Moon and Sun being at right angles relative to the Earth Gravitational Pull The invisible force that exists between all objects that have mass. The greater the mass, the greater the effect of this force Tide The daily change in ocean levels due to the gravitational force of the moon and sun exerted on Earth Explain what kind of tides the Earth would be experiencing. Spring Tide because the Sun, Moon, and Earth are aligned. Neap Tide because the Sun, Moon, and Earth are aligned. Spring Tide because the Moon is perpendicular to the Sun relative to the Earth. Neap Tide because the Moon is perpendicular to the Sun relative to the Earth. Explain what kind of tides the Earth would be experiencing. Spring Tide because the Sun, Moon, and Earth are aligned. Neap Tide because the Sun, Moon, and Earth are aligned. Spring Tide because the Moon is perpendicular to the Sun relative to the Earth. Neap Tide because the Moon is perpendicular to the Sun relative to the Earth. Explain what kind of tides the Earth would be experiencing. Spring Tide because the Sun, Moon, and Earth are aligned. Neap Tide because the Sun, Moon, and Earth are aligned. Spring Tide because the Moon is perpendicular to the Sun relative to the Earth. Neap Tide because the Moon is at 90 degree angle to the Sun Explain what kind of tides the Earth would be experiencing. Spring Tide because the Sun, Moon, and Earth are aligned. Neap Tide because the Sun, Moon, and Earth are aligned. Spring Tide because the Moon is perpendicular to the Sun relative to the Earth. Neap Tide because the Moon is at a 90 degree angle to the Sun. Juan lives near the Pacific Ocean and likes to observe the tides. Juan notices that about twice a month the range between the high and low tide is greater than normal. What is the most likely reason for Juan's observation? The Moon must be closer to the Earth causing a larger change in tides The Sun and Moon are aligned, causing a spring tide The Moon is perpendicular to the Sun relative to earth, causing a neap tide Jupiter is closer in its orbit to Earth In the diagram below, which location(s) would be experiencing high tide? Location A and B Location A only Location B and D Location A and C What tidal conditions would you expect when the Earth, Sun, and Moon are configured according to the diagram below? Tides with a greater range between high and low tides Tides with a smaller range between high and low tides Only high tides Only low tides Which phases of the moon are involved with neap tides?

First Third New Full Waning Crescent Waning Gibbous Waxing Gibbous Waxing Crescent Fill in the seasons for the Northern Hemisphere on the picture below. Word Bank: Spring, Fall, Winter, Summer Summer Fall Winter Spring We have seasons because... The earth is tilted on its axis and it rotates. The earth is tilted on its axis and it revolves around the Sun. The earth revolves around the sun. The moon is tilted on the its axis and rotates. In the picture above, which season is taking place in the northern hemisphere? Fall Winter Summer Spring Which diagram best represents the tilt of Earth's axis that causes the Northern Hemisphere seasons shown? (Diagrams are not drawn to scale.) In the picture above, what season is taking place at letter B in the southern hemisphere? Summer Winter Fall Spring North South East West What degree is the earth's axis tilted? 32.5 53.2 23.5 35.2 Label: Revolutionand Rotationon the correct image below.
