This picture explains moon phases.

Waxing; the moon anytime after new moon and before full moon.                                    Waning; the moon anytime after a 1/2 moon and before a full moon.                               Gibbous; more that half full.         

I realize a pattern when we have a waxing moon. I see that it starts lightly lighted up and progressively gets more light, compared to a waning moon which does the same thing but stops half way.


lunar cycle; the cycle of the appearance of phases of the earths moon. (lasts about 30 days.)

This Picture is showing the causes of eclipses.

Who was Copernicus? Nicolai Copernicus was born in1473 and died in1543 radically changed our understanding of astronomy when he proposed that the sun, not Earth, was the center of the solar system. This led to our modern understanding of the relationship between the sun and Earth. He also helped explain time in a theoretical way.

Why do we have seasons? We have seasons because the way the sun alines with the earth while the earth is rotating on an axel and revolve around the sun showing different amounts  of light and changing seasons.

The reason why we don't have lunar eclipses every month is because of the gravitational interaction with the Sun, the line of nodes of the Moon's orbit moves over time, taking 18.6 years to make a complete cycle.

We have day and night because the Earth rotates. It spins on its axis, which is an imaginary line passing through the North and South Poles. The Earth spins slowly all the time, but we don't feel any movement because it turns smoothly and at the same speed.

This shows why we have day and night

equinox: the time or date (twice each year) at which the sun crosses the celestial equator, when day and night are of equal length (about September 22 and March 20).

Solstice: either of the two times in the year, the summer solstice and the winter solstice, when the sun reaches its highest or lowest point in the sky at noon, marked by the longest and shortest days.

Tectonic Plates

This shows the tectonic plate boundaries

Alfred Wegener was primarily known for his achievements in meteorology and as a pioneer of polar research, but today he is most remembered for advancing the theory of continental drift in 1912.

convergent; characterized by convergence                                                                         divergent; to diverge                                                                                                             transform boundaries; the shifting of boundaries                                                               rift zone; a system of related, narrow depressions between parallelfaults.          subduction zone; the act of subducting.

The Pacific plate is off the coast of Washington.

The Cascade Mountains fall along the two tectonic plates. These tectonic plates provide the large roles of creating the terrain that falls along. The plates are the reason why we have the cascade mountains.

Rockin' and Rollin'

rock cycle

There are 3 types of rocks, sedimentary, metamorphic, igneous. Some types of sedimentary rocks are limestone and sandstone. Some types of metamorphic rocks are Gneiss and Granite. Some types of igneous rocks are Obsidian and Basalt.


Sedimentary rocks; formed from particles of sand, shells, pebbles, and other fragments of material.

Metamorphic rocks; a result of a transformation of a pre-existing rock. Reformed by heat.

Igneous rock; formed through the cooling and solidification of magma or lava.

Stratification; The process by which materials form or are deposited in layers, as in sedimentary rocks and some igneous rocks.

This is showing stratification

Geologists generally know the age of a rock by determining the age of the group of rocks, or formation, that it is found in. The age of formations is marked on a geologic calendar known as the geologic time scale. Development of the geologic time scale and dating of formations and rocks relies upon two fundamentally different ways of telling time: relative and absolute. Relative dating places events or rocks in their chronological sequence or order of occurrence. Absolute dating places events or rocks at a specific time. If a geologist claims to be younger than his or her co-worker, that is a relative age. If a geologist claims to be 45 years old, that is an absolute age.

There are many different ways living organisms have shape like

*From gravity

*From Lava cool in places and building up

*from tectonic plates


Dem Brain Cells Doe

Brain cell

Cell; the smallest structural and functional unit of an organism, typically microscopic and consisting of cytoplasm and a nucleus enclosed in a membrane.

What are the diffences between animal and plant cells.

              Although, the overall function of the cell is the same, there are some important differences between animal and plant cells. The first difference is that plant cells have an organelle called chloroplast. Chloroplasts contain a pigment called chlorophyll (which gives the plant tits green color).

The difference between Animal and Plant cells.

Cell Functions

   Muscle; contain protein filaments of actin and myosin that slide past one another, producing a contraction that changes both the length and the shape of the cell.                    

Nerve; Neurons are highly specialised to transmit messages from one part of your body to another. All neurons have a cell body and

bone; One function of the osteocyte might be the remodeling of the bonethrough growths of new arms on the cell.       

Cartilage; Light micrograph of hyaline cartilage showing chondrocytes and organelles, lacunae ... The division of cells within cartilage occurs very slowly, and thus growth in.
