Waxing: The word crescent refers to the phases where the moon is less than half illuminated. Waxing essentially means "growing" or expanding in illumination.
Waning: The word crescent refers to the phases where the moon is less than half illuminated. waning means "shrinking" or decreasing in illumination.
Gibbous: The word gibbousrefers to phases where the moon is more than half illuminated.
Crescent: The word crescent refers to the phases where themoon is less than half illuminated.
As the moon is waxing, it gets fuller-more illuminate-from the right to the left. Also as it is waxing it is starting smaller and working its way up to a Full Moon-moon that is fully lit, as big as it gets. As the moon is waning, it shrinks-losing its illumination-going from left to right. When the moon is waning it is slowly losing its light from a full moon down to a New Moon-moon does not have any light, looking like there is no moon.
Lunar cycle: A lunar phase of the moon is the portion of the moon illuminated. The lunar cycle is the waxing and waning of the moon in a cycle, as the moon changes it position to the sun, as us, Earth.
Earths Seasons & #Eclipses
Copernicus: Copernicus was the man who first proposed that the sun was the middle of our solar system. This lead to our modern understanding between the earth and the sun.
Why do we have seasons? The Earth orbits the sun, and, at the same time, spins on an axis. This means that since the Earth is spinning on an axis, different hemispheres are exposed to different amounts of sunlight thoughout the year. The sun is our source of light, energy and heat, changing intensity and concentration of its rays give rise to the seasons of winter, spring, summer and fall.
In the winter, even though the sun is closer to Earth, it isn't warmer because our hemisphere is not facing the sun. Therefore, the hemisphere facing the sun is warmer.
Their isn't lunar #eclipses each month because the Sun isn't exactly in line with the Earth and the moon. So, we would not have a lunar/solar eclipses each month, but maybe a couple times per year.
We have day and night because the Earth spins. 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.
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) another term for equinoctial point.
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.
Who was Alfred Wegener? Alfred Lothar Wegener was a German polar researcher, geophysicist and meteorologist. During his lifetime he was primarily known for his achievements in meteorology and as a pioneer of polar research.
Convergent boundary: is an actively deforming region where two (or more) tectonic plates or fragments of the lithosphere move toward one another and collide. Also know as a destructive plate boundary.
Divergent boundary: is a linear feature that exists between two tectonic plates that are moving away from each other.
Transform boundary: is where two tectonic plates side alongside each other.
The plate tectonic on the coast of Washington and Oregon is call the Juan De Fuca.
The Juan De Fuca has an effect on the cascades because of the way the plate tectonics move, either moving at each other, convergent, moving away from each other, divergent, or moving with each other, transform. The different way the plates move can make different physical features on land, such as volcanos, steeper mountains, valleys, ridges, earthquakes.
Convection currens effect plate tectontics because they are mechanisms that
Sedimentary: a rock that has formed from sediment deposited by water or air.
ex. breccia, conglomerate, sandstone and shale
Igneous: a rock having solidified from lava or magma.
ex. diorite, gabbro, granite and pegmatite
Metamorphic: a rock denoting rock that has undergone transformation by heat, pressure, or other natural agencies.
ex. gneiss, phyllite, schist and slate
Stratification: is a system or formation of layers, classes, or categories.
Studying the amount of layers in rocks can determine the age because, the deeper down the layers are, the longer they have been there. The colser the layers are to the suface show that they have not been there as long as rocks that have layers deeper into the surface. Though you cannot determine the exact age of the rock layers, there can be close estimations.
Geological events causing huge blocks of sedimentary layers to be tippped, or having older layers if sedimentary on the top and younger on the botttom because of the heat or magma from under the Earths crust causing more layers to be made on the bottom of the sedimentary layers, making it older layers on the top and newer layers on the bottom. Also sedimentary blocks can be tipped by Earthquakes and hard wind storms.
Living organisms form landforms because when they die, there skeleton builds up and Creates another layer on the Earth. Also, they build dams and that creates lakes. They dig holes in the ground making a place for water to run into. They eat vegetation causing erosion.
Cell: the smallest structural and functional unit of an organism, typically microscopic and consisting of cytoplasm and a nucleus enclosed in a membrane. Microscopic organisms typically consist of a single cell, which is either eukaryotic or prokaryotic.
One difference between plant and animal cells is that plant cells contain
chloroplast, which contains a pigment called chlorophyll (that gives the plant the green coloring.) Another difference is that animal cells are smaller than plant cells and have a membrane around them that is flexible and allows molecules, gases and nutrients to pass into the cell. Plant cells are larger and in addition to a membrane they have a rigid cell wall.
Nerve cells: Nerve cells are highly specialised to transmit messages from one part of your body to another. All neurons have a cell body and one or more fibers.
Epithelial cells: Functions of epithelial cells include secretion, selective absorption, protection, transcellular transport and detection of sensation.
Adipose cells: Its main role is to store energy in the form of fat, although it also cushions and insulates the body.
Tissues work together to perform specific activies needed for the organism to survive such as, the heart, brain, skin, etc. Then, groups of two or more tissues that work together to perform a specific function for the organism, like the nervous system, circulatory system, etc. Therefore allowing living things to carry out living life processes.
Your digestive system is uniquely constructed to perform its specialized function of turning food into the energy you need to survive and packaging the residue for waste disposal.
The Circulatory System is responsible for transporting materials throughout the entire body. It transports nutrients, water, and oxygen to your billions of body cells and carries away wastes such as carbon dioxide that body cells produce.
The respiratory system is made up of several organs that work in tandem to help you breathe. Each part of your body works together seamlessly to create the breathing that you need to survive.
The digestive system breaks down the food we eat into smaller nutrients which are moved throughout our bodies by the circulatory system. The respiratory system captures oxygen from the air and releases toxic carbon dioxide to the air; these chemicals are also moved through the body via the circulatory system.
