Waxing: The term used to desceibe the period of the Moon as it moves from a Full Moon to a New Moon, decreasing invisibility with respect to a Earth-bound observer.

Waning: The term used to describe the period of the Moon as it moves from a New Moon to a Full Moon, increasing invisibility with respect to an Earth-bound observer.

Gibbous: There are two Gibbous phases of the Moon, the first is representing the growing Moon between the First Quarter and the Full Moon, the second is representing the Moon growing smaller as it shriks down from the Full Moon to tbe Last Quarter. These phases are reffered tooas the Waning and Waxing Gibbous respectively.

Cresent: The famous image of the Moon frequently used in the media, consists of only a thin cresent slice of the Moon being visible from Earth. This phase of the Moon occurs just after the New Moon phase, which is also know as Dark of the Moon. There is also a Cresent Moon phase there is also a Cresent Moon phase just prior to thenexf New Moon as well.


Copernicus was a Renaissance mathematician and astronomer who formulated a model of the universe that placed the Sun rather than the Earth at its center.

We have seasons because the earth rotates on an axis that's tilted in its orbit. That 23.5 degree tilt causes the different hemispheres to be at different angles to the sun at different times of the year.

We have day and night because when the earth rotates on the axis it is moving away from the sun so you do not get any sun at certain points and that is night time

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.


2. Alfred Lothar Wegener was a German polar researcher, geophysicist and meteorologist. During his lifetime he was primarily known for his achievements in meteorology. meteorology is the interdisciplinary scientific study of the atmosphere.
3.convergent is coming closer together, especially in characteristics or ideas.
divergent is tending to be different or develop in different directions.
transform boundaries is a transform fault or transform boundary, also known as conservative plate.
7.rift zone is is 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.
8. subduction zone are sites of convective downwelling of Earth's lithosphere.

You need to complete the tackk about Eclipses. See mine. Also, make your hashtag plural so I can find it again.
