Sometimes the Earth, sun, and moon line up so that one object is blocking or shadowing another

Why do you think we have tides?
Why does the Earth have Why does the Earth have tides?tides?
The sun and moon pull on the Earth’s water causing the tides to rise
Phases of the MoonPhases of the Moon
TidesTidesPeriodic rise and fall of large bodies of water caused by the gravitational attraction of the moon to the Earth.
High TideHigh Tide
Outward bulge of water. Occurs twice per day
Low TideLow TideTrough left by the movement of water to the
two bulges. Occurs twice per day
Spring TideSpring TideFull or new
moon causes the gravity of sun and moon to combine causing extreme high and low tides
Neap tideNeap tide Moon is in Quarter
phase causing the gravity of the sun and moon to cancel each other. (Sun and moon pull at a right angle)
Smaller difference between high and low tides

The Moon’s Tilted OrbitThe Moon’s Tilted Orbit
The moon’s orbit is tilted by 5 degrees, so it is infrequent for the sun, moon, and earth to all line up. When these objects do align, eclipses occur.
EclipseEclipseWhen the moon’s shadow hits Earth or Earth’s shadow hits the moon, an eclipse occurs
Types of EclipsesTypes of EclipsesSolar eclipse – solar
is Latin for sun Occurs when the moon
passes directly between Earth and the sun, blocking sunlight from Earth
Lunar eclipse- lunar is Latin for moon
Occurs when Earth blocks sunlight from reaching the moon
Solar EclipseSolar Eclipse
umbra
penumbra
Total Solar Eclipse– Light from the sun is
completely blocked by the moon; within the umbra
– Umbra- the very darkest part of the moon’s shadow on Earth
Partial Solar Eclipse– Part of the sun is
visible from Earth within the penumbra
– Penumbra- larger part of the moon’s shadow on Earth
Total Lunar Eclipse
When the moon is in Earth’s umbra, a total lunar eclipse occurs.
•Can be seen anywhere on Earth that the moon is visible
Partial Lunar Eclipse
Occurs when the moon passes partly into the umbra of Earth’s shadow; can appear orange
•The edge of the umbra appears blurry, and you can watch it pass across the moon for two or three hours.
