Waning Moon — The term used to describe the period of the Moon as it moves from a Full Moon to a New Moon, decreasing in visibility with respect to an Earth-bound observer.
Gibbous Moon — There are two Gibbous phases of the Moon, with the first representing the growing moon between the First Quarter and the Full Moon and the second when it describes the Moon growing smaller as it shrinks down from the Full Moon to the Last Quarter.
Crescent Moon — The famous image of the Moon frequently used in the media, consisting of only a thin crescent slice of the Moon being visible from Earth. This phase of the moon occurs just after the New Moon phase, which is also known as Dark of the Moon.
Waxing Moon — The term used to describe the period of the Moon as it moves from a New Moon to a Full Moon, increasing in visibility with respect to an Earth-bound observer.
The pattern you see when you have a waxing moon is only 1/4 or a crescent of the moon . When you have a waning moon you see the whole moon other then that "waxing" or 1/4 or crescent part of the moon.
Lunar cycles are a period of 19 years (235 lunar months), after which the new and full moons return to the same days of the year.
Nicolaus Copernicus was a astronomer who formulated a model of the universe that placed the Sun rather than the Earth at its center.
We have season because the earth makes its yearly journey around the sun. The Earth's 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, causing the tempature to chang the causing the weather, plants, extra to chang to causing seasons.
In winter, the sun is closer to Earth, why isn't it warmer? During the winter, the sun's rays hit the Earth at a shallow angle. These rays are more spread out, which minimizes the amount of energy that hits any given spot. Also, the long nights and short days prevent the Earth from warming up. There for making winter not worm.
An eclipse of the Moon is different from Moon’s phases, because the moon is at different places in the sky and its also at different times.
Day/Night is caused my the Earths rotation and when the Earth faces the sun its day and when its faced away from the sun its night on that side of the Earth
Equinox is when the time or date at which the sun crosses the celestial equator.
Solstice is when the sun reaches its highest or lowest point in the sky at noon, marked by the longest and shortest days.
Alfred Lothar Wegener was a German polar researcher, geophysicist and meteorologist. During his lifetime he was primarily known for his achievements in meteorology.
]Convergent: coming closer together, especially in characteristics or ideas.
Divergent: A tectonic boundary where two plates are moving away from each other and new crust is forming from magma that rises to the Earth's surface between the two plates.
Transform boundaries: A boundary since these faults neither create nor destroy lithosphere.
The cascad plate and the Juan de Fuca Plate is just of the coast of Washington.
The Cascades volcanoes define the Pacific Northwest section of the ‘Ring of Fire', a fiery array of volcanoes that rim the Pacific Ocean.the run from washington all the way down to the even of Califorinia.
Convection currents in the magma drive plate tectonics. The tectonics move the plates.
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: sites of high rates of volcanism, earthquakes, and mountain building.
"Channeled Scablands" were formed from the Ice Age floods accelerated across the tilted surface of the Palouse slope, causing massive erosion. Much of the eroded sediment was carried all the way to the Pacific Ocean.
Rocks and Roles
Sedimentary: a rock that has formed from sediment deposited by water or air.Coal
Metamorphic: rock that has undergone transformation by heat, pressure, or other natural agencies.Amphibolite
Igneous: a rock having solidified from lava or magma. Pegmatite
Stratification: the layering that occurs in most sedimentary rocks and in those igneousrocks formed at the Earth's surface.
The age of landforms can be estimated by studying the number and thickness of rock layers, as well as fossils found within rock layers. this is because as the years go buy the rocks create a new layer. they make layers by the dirt , sand, and rocks pialing up and makeing new layers. some times there may be old rocks, plants, and dead animals stuck in thoughs layers, there for causing fossils.
Older rock layers some times get on top of younger rock layers when there are earth quaks, rock slids, or when the earths plates move.
Coral reefs are not only spectacular marine environments, but they are one of the oldest ecosystems (community of plants and animals interacting with their environment) on Earth. They are created by colonies of organisms called coral polyps (pronounced PAH-lips).

cell: smallest structural and functional unit of an organism, typically microscopic and consisting of cytoplasm and a nucleus enclosed in a membrane.
other than size, the main structural differences between plant and animal cells lie in a few additional structures found in plant cells.
the Vacuole, nucleus, cytoplasm, lysosome, cell membrane, mitochondrion, endoplasmic reticulum, and golgi apparatuse are different sizes, and different shapes. that animal cell is more round than a plant cell and a plant cell has a smaller nucleus then the animal cell dose.
muscle: a band or bundle of fibrous tissue in a human or animal body that has the ability to contract, producing movement in or maintaining the position of parts of the body.
nerve:a whitish fiber or bundle of fibers that transmits impulses of sensation to the brain or spinal cord.
bone: any of the pieces of hard, whitish tissue making up the skeleton in humans and other vertebrates.
In unicellular organisms, the single cell performs all life functions. It functions independently. However, multicellular organisms have various levels of organization within them. Individual cells may perform specific functions and also work together for the good of the entire organism. The cells become dependent on one another.
Your lungs are part of a group of organs and tissues that all work together to help you breathe. This system is called the respiratory system. The main job of the respiratory system is to move fresh air into and get waste gases out of the body.
All tese parts interact by using cell.
