tides

QuestionAnswer
Why do we see a full moon when the moon is in that position? The side of the moon that is illuminated by the sun is also the side of the moon that people on Earth are looking at.
What causes spring tides and neap tides? ST: the sun and moon's gravl pulls are working together to make the tidal bulge more dramatic. NT the gravl pull of the sun works against the gravl pull of the sun, so the TB is closer to the circle snd the HT and LT are closer to the same.
Explain what causes high and low tides. HT and LT are caused by the moon's gravitational pulls on the oceans, creating a tidal bulge. The bulge is deeper on the side of the earth close to the moon and on the side of the earth opposite the moon.
Why do solar eclipses occur? When the moon orbits the earth and winds up exactly between the sun and the earth.
Why do lunar eclipses occur? Earth lines up perfectly between the moon and sun. The earth blocks the sun's light from reaching the moon.
Why don't eclipses occur every month? Moon orbits at a slight angle, 5.14 degrees. Therefore, most months the moon is above or below the earth as it orbits, so an eclipse is avoided.
Spring tide When the moon, sun, and earth are in line; happens twice a month; the largest difference between high and low tide.
Neap tide The smallest difference between high and low tide; happens twice a month; when the moon, sun, and earth are at a 90 degree angle.
High tide Time when water level is the highest; happens twice a day.
Low tide Time when water level is the lowest; happens twice a day.
Solar eclipse When the moon casts a shadow on earth's surface; when the moon is perfectly aligned between the sun and earth; only occurs during a new moon
Lunar eclipse When the earth casts a shadow on the moon's surface; when the earth is perfectly aligned between the sun and moon; only occurs during a full moon.
Corona The outer atmosphere of the sun; the only part of the sun visible during the total solar eclipse
Umbra the darker, central part of a shadow created by a moon or planet
Penumbra The lighter outer shadow created by a moon or planet
