Lunar Cycle

Waning Moon- When the moon moves from a Full Moon to a New Moon, decreasing in visibility with respect to an Earth-bound observer.'

Waxing Moon- When the moon moves from a New Moon to a Full Moon, increasing in visibility with respect to an Earth-bound observer.

Gibbous Moon- The growing moon between the First Quarter and the Full Moon and shrinking when it's going from a Full Moon to the Last Quarter.

Crescent Moon- This phase of the moon occurs just after the New Moon phase, which is also known as Dark of the Moon. It also occurs right before the New Moon.  

The pattern of the Waxing and Waning Moon are similar in many ways due to the positions, they're just different due to the time of the cycle. The Waxing Moon increases it's visibility while the Waning Moon decreases.

Lunar Cycle- 29.53059 days (The moon's full cycle.)

Solar Eclipse

Nicolai Copernicus (1473-1543) created the theory that the Sun was the center of our solar system.

We have seasons because of the way we rotate around the sun. The Northern Hemisphere will be summer, while the Southern Hemishpere will be winter. We are also at an angle.

In the winter for the Northern Hemishpere it's cold, while in the Southern Hemisphere it's warm because of the angle and positon the Earth is from the Sun.

An eclipse doesn't happen every month because it depend on the location of the moon and sun, and their is many types of eclipses that can happen.   

We have day and night because the Earth rotates every 24 hours or day. When you face away from the sun, then it is nighttime. If you face the sun it is daytime. That's why the world has different time zones based on where their facing.

Equinox- the time when the sun crosses the plane of the earth's equator, making night and day of approximately equal length all over the earth and occurring about March 21 (vernal equinox or spring equinox) and September 22 (autumnal equinox).

Solstice- either of the two times a year when the sun is at its greatest distance from the celestial equator: about June 21, when the sun reaches its northernmost point on the celestial sphere, or about December 22, when it reaches its southernmost point.Compare summer solstice, winter solstice.


Alfred Wegener was the scientist who proposed the Continental Drift Theory in the early twentieth century. His hypothesis proposed that the continents had once been joined, and over time had drifted apart.

Convergent- characterized by convergence; tending to cometogether; merging.

Divergent- diverging; differing; deviating.

Transform Boundaries-Places where plates slide past each other.

The plate right of of Washington State's coast is called the Juan de Fuca Plate. It affects the Cascade Mountains by develpoing volcanoes such as Mt. St. Helens and Mt. Rainier, and cause them to erupt. It also develops the mountains.

Convection Current-the transfer of heat by the mass movement of heatedparticles into an area of cooler fluid. Convection currents in the magma drive plate tectonics.

Rift Zone- a feature of some volcanoes, especially shield volcanoes, in which a linear series of fissures in the volcanic edifice allows lava to be erupted from the volcano's flank instead of from its summit.

Subduction Zone- The biggest smash-up on Earth, marking the collision between two of the planet's tectonic plates, the pieces of crust that slowly move across the surface over millions of years. When two tectonic plates meet, one may slide underneath the other, curving down into the mantle.

The scabland was created where the Ice Age floods accelerated across the surface of the Palouse slope, causing massive erosion. Much of the eroded sediment was carried all the way to the Pacific Ocean. Amazing, right?
