How do the Sun Moon and Earth interact

How do the Sun, Moon, and Earth interact to create different observable features from the Earth? 1

Seasons

Seasons Look at this diagram. Notice how the Earth is always tilted in the same direction. As the Earth , the part of revolves Earth tilted toward the sun changes.

During what seasons is the North Pole tilted towards the sun? Why? summer

During what seasons it the North Pole pointing away from the sun? Explain. winter

How do tides change from high tide to low tide? • Two big bulges of water form on the Earth: – one directly under the moon – another on the exact opposite side As the Earth spins, the bulges follow the moon.

Gravitational Effect of the Sun • Neap Tides – Earth, Moon, and Sun form right angles – High Tides are lower and Low Tides are higher than normal • Spring Tides – Earth, Moon, and Sun are lined up – High Tides are higher and Low Tides are lower than normal

Solar Eclipses How do Eclipses differ from Phases of the moon? • When the Moon’s shadow covers part of the Earth • Only happens at New Moon

Here is an animation showing a total solar eclipse

This is an animation showing a total lunar eclipse from start to finish.

Using a diagram of the Earth, Moon, and Sun, how can you determine the phase of the moon? The moon looks different throughout the month. Sketch a diagram of the Earth, Moon, and Sun that demonstrates how these phases occur. Next, we will test these diagrams.

Phases - Causes When the sunlight reflects off the Moon’s far side, we call it a New Moon When the sunlight reflects off on the Moon’s near side, we call it a Full Moon Between New and Full, we see parts of the daytime side of the Moon.
