        Moon Phases & Tides
         

  Waxing: The moon at any time after new moon and before full moon, so called because its illuminated area is increasing. Cf. Waning Moon.

  Waning: Same as the waxing moon. The moon any time after new moon and before full moon.

  Gibbous: When a moon is more than a half full, But not fully illuminated.

  Crescent: Is a moon that is between a half and new moon, or between New moo and half moon.

  The pattern for a waxing/waning moon is exactly every 29.5 days. A waning crescent, last quarter, first quarter, waxing crescent, and waxing gibbous.

  The lunar phase or phase of the moon is the shape of the illuminated(sunlit) portion of the moon as seen by an observer on Earth. This cycle last up to 27.5 days, for a full cycle.

Earths Seasons/Eclipses

Copernicus was a Renaissance and astronomer.

We have seasons because the earth is tilted (wonky) as it makes its yearly journey around the sun. The earths axis is tilted at an angle of 23.5 degrees. This means that the earth is always "pointing" to one side as it goes around the sun.

The reason why its not warmer in the winter is because its not based on the heat from the sun its based on the atmospheres temperature.

There arent always a lunar eclipse every month because its not based on the cycle by the month but by how long the cycle takes by the days.

We have days and nights because the Earth rotates. It spins on its axis, which is an imaginary line passing through the north and the south poles.

Equinox and Solstice: The days are longer around the summer solstice and shorter around the winter solstice. When the Sun's path crosses the equator, the length of the nights at latitudes +L and -L are of equal legth. it is known as a Equinox.

Plate Tectonics #platetectonics

Alfred Wegener was a German Polar researcher, geophysicist and meteorologist. He also theorized continental drift and plate tectonics.

In theory of the plate tectonics the Earths crust is broken into plates that move around relative to each other. As a result of this movement, three types of plate boundaries are formed: convergent divergent and transform boundaries.

The tectonic plate that's off the coast of Washington is called Juan de Fuca Plate.

The ridges of the Juan de Fuca plates spread apart which help creates and causes the Cascade Mountains to form.

Convection Currents are a fluid that results from convection.
